    I have a 2002 Ford f 150 and my radiator is loosing all fluid by the head gasket. Im not too mechanically inclined but I do know a little bit. I don’t have a direct cap to my radiator, everything goes thru the reservoir. How do I apply your product to fix my truck. I have heard many great things about it and want to try and save my baby!

    • BlueDevil Pro on May 20, 2013 at 2:36 pm

      If your vehicle has a reservoir rather than a radiator cap, instead of pouring it through the reservoir, with the car off and engine cold, you may add the product through the top radiator hose. Once it has been added reconnect the hose and start the idle from that point.

      • Joshua R on July 6, 2015 at 9:15 pm

        I have failed to keep the idle going so did not have enough time. I also have a F150 with no radiator cap and did the slow pour into the reservoir which is pressurized 16 lbs. – but only after the cap is back on the reservoir I presume.
        If I try again by pouring it into the disconnected top hose, do I still pour it slowly or just add it all and reconnect?
        Thanks. Still hopeful.

          Joshua-

          If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there. Once it has been added reconnect the hose and start the idle from that point.

            Will this product work on a 2006 Ford F250 super duty 6.0 Diesel V8 turbo?? I know it would take 32oz of this product if it will work.



          • BlueDevil Pro on December 13, 2018 at 9:07 am

            Richard-

            Thank you for asking about your Ford F-250. It appears the cooling system capacity in your vehicle is 27.5 quarts, approximately, 7 gallons. For a system of that size, you would want to use about 64 oz. of the product, or 4 of the 16 oz. BlueDevil Pour-N-Go Head Gasket Sealers.

            Thank you!

            Will blue devil continue to work after it seals a gasket to protect it from another leak?



          • BlueDevil Pro on January 8, 2021 at 3:03 pm

            Jerry-

            The product only reacts to heat once (one heat cycle), so it will not continue to react or continue to seal after the initial procedure is completed. Feel free to contact our technical support line at 888-863-0426 with any other questions.

            After removing the top radiator hose, do you pour directly into the hose towards the engine or towards the radiator?



          • BlueDevil Pro on February 8, 2021 at 9:39 am

            MTT-

            You would want to pour the product directly into the radiator. You can pour it in through the hose itself, or disconnect the hose from where it clamps to the radiator and pour it in through there. Pour speed would not matter with the vehicle off, engine cold.

            Hello. I have a 2010 Toyota tundra sr5 with a v8 5.7 liter engine. I tried adding one 16 Oz bottle of your blue devil pour and go to my radiator today. I drained the coolant from the radiator and added it to the radiator. I let it run the required 50 minute time. It began to overheat almost half way through that time but didn’t totally go to the H. Do I need to add more of your product to my radiator? I did not remove the thermostat as it is brand new and was just replaced along with the water pump and serpentine belt.



          • BlueDevil Pro on December 11, 2023 at 8:53 am

            Melissa-

            Thank you for asking about your Toyota Tundra. Your vehicle would’ve required two 16 oz. bottles being added at one time, as it is a V-8. The product only goes through one heat cycle, so it is not the kind of additive where you can add half now and the other half later. Besides overheating, what are the symptoms the vehicle was having? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

            What happens if I put it in the reservoir instead?



          • BlueDevil Pro on February 12, 2024 at 9:19 am

            Shawn-

            It is very important that the product is added directly into the radiator when the engine is cold. If the product was added in through the reservoir/overflow tank, it would not pull into the system quick enough, and would start to react/harden before having a chance to look for the leak. Doing so would like cause an adverse reaction within the cooling system.

            Thank you!

          • Charlie Gunther on July 5, 2024 at 4:08 am

            I have a 2010 Toyota Prius. Should I use the pour and go or the yellow label? Should I take the thermostat out? I have no problem doing that if it increases the chances of a long term seal.



          • BlueDevil Pro on July 8, 2024 at 9:07 am

            Charlie-

            You may use either of the Head Gasket Sealers that we manufacture. The “Pour N Go” (16 oz./white label) is an easy to use, less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (32 oz./yellow label) requires both the removal of the thermostat and a flush before applying the product; the 32 ounce (yellow label) is the more concentrated formula.
            The product with the yellow label will give you best overall results as long as you are willing to remove the thermostat and flush the system prior to use. You would be using about 12 oz. of the product either way.

            Thank you!

          How long does blue devil react.if i put it in the system for 50mins and leave it in system.when i crank my car the next day does it react again.plus does blue devil pour and go seal cylinsr heads or block also

          • BlueDevil Pro on August 3, 2020 at 8:40 am

            Trenton-

            The BlueDevil Head Gasket Sealer only reacts to heat one time (one heat cycle). After the 50 minute idle and the vehicle cools, the product will not continue to react or continue to seal. Yes, the Pour-N-Go Head Gasket Sealer would be able to treat warped/cracked heads and a leaking block as well.

          If you are using BlueDevil Pour N Go Head Gasket Sealer (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) you will not need to flush the system or remove the thermostat prior to use. This is a less concentrated formula that is made to be “easy-to-use”. The larger 32 ounce BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/) is the product with the additional directions of removing thermostat and flushing the cooling system.

          • Jess Sal on September 4, 2017 at 10:39 pm

            My vehicle needs the coolant refilled once a week (about 1/3 of a container of coolant). I let my reservoir go super low so that i could pour 32 oz (two of the 16 oz). I let my vehicle cool and removed the radiator cap. I turned the vehicle on and put my heater on full blast. I then tried to pour the blue devil pour n go (16 oz) into the radiator and it just settled/pooled and did not accept more than 1-2 oz. Any idea why that would happen??



          • BlueDevil Pro on September 5, 2017 at 10:28 am

            Jess-

            Were you getting combustion/exhaust gases blowing into the cooling system and creating pressure? Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

            Unfortunately, we do not manufacture a product intended to stop oil from mixing in with the coolant. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. A hard part repair may be your best option.

            Steven-

            If your vehicle only has a reservoir/expansion tank rather than a radiator cap, instead of pouring BlueDevil through the reservoir/tank, with the car off and engine cold you should disconnect the top radiator hose and add the product there; do not pour it into the reservoir. It may be added into the hose or the opening on the radiator. Once BlueDevil has been added, reconnect the hose and start the idle from that point.

            The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. It should not be used as a preventative measure/preventative maintenance. You could cause harm adding the product to a system that doesn’t have a leak.

            I didn’t notice the directions said the engine needs to be cold before putting Blue Devil. I was rinsing the radiator so I poured it in when it was still a little warm. Is that OK? Or will it start reacting right away if it’s poured into a warm engine?



          • BlueDevil Pro on October 17, 2022 at 8:41 am

            Deforest-

            Adding the BlueDevil Head Gasket Sealer to the radiator when the engine is warm could cause the product to start reacting prematurely. The product reacts around 150 degrees Fahrenheit. Please contact our technical support line at 888-863-0426 for further assistance.

          The product should be poured in through the radiator cap. If the vehicle does not have a radiator cap, with the vehicle off and engine cold, you can remove the upper radiator hose, pour the product in through there, reconnect the hose and start the idle from that point.

            The BlueDevil Head Gasket Sealer (32 oz. yellow label) has a slightly higher concentrated formula compared to the Pour-N-Go Head Gasket Sealer, and would require the removal of the thermostat and flushing the cooling system prior to use.

          That is excellent to hear! The system should be bled to get rid of any potential air pockets in the cooling system. You can do this by simply draining and refilling the system. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring it through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there (it may be added into the hose or through the opening). The speed of the pour will not make any difference as the engine will be off. Once it has been added reconnect the hose and start the idle from that point. DO NOT pour the product in through your reservoir.

        Hi so I have 2006 2.7 liter dodge charger I used the blue devil pour n go I don’t have a radiator cap either but YouTube videos said it was supposed to go through the resivoir well I ended up removing the thermostat as well and I left it out my car seems to run so much better …but what will the long term effects be if I don’t put it back in

        • BlueDevil Pro on February 14, 2019 at 9:20 am

          Amber-

          Thank you for asking about your Dodge Charger.

It may be added into the hose or the opening on the radiator. Once BlueDevil has been added, reconnect the hose and start the idle from that point.
          Leaving the thermostat out will only be an issue if you are worried about getting heat. If you live in a warmer climate, you probably wouldn’t need to put it back in.

        • BlueDevil Pro on January 4, 2022 at 8:34 am

          You would need 32 oz. of the BlueDevil Head Gasket Repair to treat your Dodge Ram 1500. One 16 oz. bottle would treat up to 3 gallons cooling system capacity. It appears your system holds a little more than 4 gallons.

      • Daisy Cooper on May 29, 2022 at 5:28 pm

        Which side of the upper radiator hose do you remove, the side with thermostat or the side that goes into radiator? Also will this help with oil leaking? I know it helps with head gasket symptoms. Oil is leaking around the head and dripping down and causing smoke after engine gets hot.

        • BlueDevil Pro on May 31, 2022 at 9:17 am

          Daisy-

          Either way is fine, as long as it is added directly into the radiator. Unfortunately, the product would not be intended for a head gasket leaking oil. Replacing the head gasket would be the only remedy in this instance.

        • BlueDevil Pro on June 9, 2022 at 8:29 am

          Giordan-

          The reason the product can’t be added to the reservoir/overflow tank is that the BlueDevil has to be added to the radiator when the engine is cold. If you add it through the reservoir, it may not pull into the cooling system until the engine is hot, so it would essentially be like adding the product to a hot engine.

        • BlueDevil Pro on June 19, 2023 at 9:16 am

          Hailey-

          In terms of using the BlueDevil Pour-N-Go Head Gasket Sealer, we’d recommend at least 2 hours of a cool down since the vehicle had been run last. You should be good to go at this point.

          Thank you!

            Heath-

            Thank you for asking about your Dodge Journey. You would want to try to bleed the air out of the cooling system prior to starting the 50 minute idle. Once you add the product, you would put the cap back on, put the heater on with blower to the max, and allow the engine to idle for 50-minutes.

            Thank you!

      I have a slow antifreeze leak from what I was told is a blown head gasket. The mechanic told me it would be $1399.00 to have it repair so it is a 2007 Toyota Camry with 190k miles I thought I would try it. Now before I have done anything the oil change guy said never put anything in the radiator because it will clog the heater core and start many problems with the engine. What is the the truth ?

      • BlueDevil Pro on March 15, 2016 at 11:23 am

        Donny-

        We have not had issues with our product restricting flow in any portion of the cooling system, including the heater core. We do recommend using BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/) to help repair the blown head gasket in your Camry.

        Deanna-

        If the vehicle is unable to idle for the full 50 minutes without overheating or stalling out, unfortunately, the leak you have or the symptoms you’re having may be a little too extreme for the product. A hard part repair may be your best option.

        The BlueDevil Pour-N-Go Head Gasket Sealer is intended for use in 4 or 6 cylinder engines and is able to be used in V-8, however, it would not be enough product to properly treat the system. Typically, you would need at least two bottles to properly treat that size of a system. Feel free to contact our technical support line at 888-863-0426 with any questions.

        Thank you for asking about your Cadillac Deville. If you used the Pour-N-Go Head Gasket Sealer, you may have noticed on the back of the bottle that it is intended for use in 4 or 6 cylinder engines, so it would not have been enough product to properly treat your V-8 NorthStar engine. Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of your product application and be able to better assist you.

      What if it starts to overheat during the 50min idle? Do I shut off immediately and try again?? Thanks!

      • BlueDevil Pro on August 22, 2022 at 8:33 am

        Mario-

        If it looks like the engine is going to overheat, you would want to shut the vehicle off. The BlueDevil Head Gasket Sealer only goes through one heat cycle, so it is important that the vehicle is able to maintain idle for the full 50 minutes. If you have to shut it off early for whatever reason, the product would not continue to react/seal after it cools down. If this happens to you, it would be best to allow the engine to completely cool, follow bleed procedures to remove any excess air, top the system back off with water/antifreeze and reassess the vehicle’s condition.

        Thank you!

        Jacob-

        You may use either of the Head Gasket Sealers that we manufacture. The “Pour N Go” (16 oz./white label) is an easy to use, less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (32 oz./yellow label) requires both the removal of the thermostat and a flush before applying the product; the 32 ounce (yellow label) is the more concentrated formula.
        The product with the yellow label will give you best overall results as long as you are willing to remove the thermostat and flush the system prior to use. You would be using about 16 oz. of the product, either way.

        Thank you!

  2. Mark Opp on June 27, 2013 at 7:05 am

    I used the pour n go version of the Blue Devil on my 97 Deville. The white smoke disappeared and the car ran as smoooth as ever. I did this back in March, but the white smoke seems to be returning. Can I use this again? I had the oil changed right away after the first treatment. I haven’t tried the big bottle because I don’t want to mess with removing the thermostat and draining the cooling system. Do you think I should take that route this time? Is it the better way to go?

    • BlueDevil Pro on July 2, 2013 at 1:32 pm

      Yes, you can definitely use BlueDevil a second time… Due to the amount of time that has passed since the first treatment this may be a new leak. The 32 oz. mechanic approved version will give you the best overall results as long as you are able to follow that set of directions. However, if it’s difficult or you are unable to remove the thermostat, we recommend using the Pour-N-Go again.

  3. Toni on July 27, 2013 at 8:20 pm

        • BlueDevil Pro on October 10, 2014 at 2:14 pm

          James-

          We would recommend using half (16 ounces) of the BlueDevil Head Gasket Sealer with a yellow label (part #38386). You will want to thoroughly flush the cooling system to help remove any rust, deposits, and/or dirtiness from the cooling system prior to use. In addition to the directions you will want to also change your oil before and after the BlueDevil process to ensure proper results.

          Feel free to contact us at 888.863.0426 with any further questions.

  4. Alex Boyette on August 18, 2013 at 8:37 pm

    1985 CHevy 350. Guess the head gasket blew. Heavy white smoke. Shut it off and one cyl was HYDROLOCKED by water. Had to pull plug and water spewed out. Also had water in oil but not a lot–I drained the oil and radiator and its been sitting a year. Question is, I can fill the oil up and water and get it started but if its spewing water into the cyl and oil too fast, and I have to idle for 50 minutes, wont I be flushing so much water that your product wont keep and also take a chance of killing my bearings?

    • BlueDevil Pro on August 19, 2013 at 1:57 pm

      Unfortunately, it sounds like your vehicle has gotten to a point where it is leaking too quickly and would not give BlueDevil enough time in the system to work properly. Based on your description the vehicle would have a lot of trouble idling for a 50 minute period. We would recommend going with the hard part repair in this case.

    • Jesse Morsie Jr. on November 21, 2014 at 7:01 pm

      My 97 blazers oil pressure sensor went out causing me to spring a leak but I didn’t allow it to run low! I got it home and replaces sensor and pulled drain plug on oil pan. When i twisted oil filter off i noticed the swirl look of mixed coolant. When i cranked it ran for only 2 seconds and it died after slight backfire. When i got it idling again it sounds weak and has slight popping. It almost sounds lime an exhaust leak. Is it too late to use Blue Devil?

      • BlueDevil Pro on November 25, 2014 at 3:52 pm

        Jesse-

        You should change your oil before running the engine anymore. In order to use BlueDevil your vehicle will need to be able to maintain an idle for 50 minutes without stalling out or overheating. If it can do so you will have a good chance at sealing the leak using the BlueDevil Head Gasket Sealer.

          Vell-

          Yes, we recommend testing the vehicle after the engine has cooled down completely. The reason that we recommend the thermostat is removed is to ensure the cooling system is free flowing with BlueDevil in the system. You should not have to replace your thermostat even though it was left in for the initial idle with BlueDevil Head Gasket Sealer.

I drove it home about 18 miles and it started running ruff and had white smoke coming out the tailpipe. I drove it one more time about four miles than parked it at the house, next morning it failed to so I haven’t tried since. I thought I was going to have to tear it down and put head gaskets in, have limit experience did it one time on a 6 banger ran great when I finished. my questions are I have water in the oil and oil in the water white smoke coming out the tailpipe and have 2 16 ounces of pour and go to do the 350 in the suv chevy… im sure I can get it running for 50 mins after I flush the radiator change oil and replace a few spark plug wires will your product work for me or do I need to exchange the 2 bottles for the 32 ounce head gasket sealer? removing the thermostat will be a job but I will follow your direction to the T… im working on the car tomorrow and plan on Tuesday or Wenseday you can message me on facebook if you would any advice would be great help we are helpless without the suv and poor I really need for your product to work thank you for listening…

      Hello! I have a 2000 Cadillac Deville. I’ve removed the thermostat, and am about to flush with blue devil flush. I have a slight leak of exhaust in the coolant. I bought the 16 oz bottle of head gasket sealer, which I will only add to the radiator after the engine cools completely. After the 50 minutes, can you drive the car? Also, my car only shows a problem after 20-30 minutes of driving. Should I drive it mid-process? Thank you! 🙂
      Sorry, I meant 32oz bottle. Don’t know why I wrote 16 oz 😐. Thanks!

      • BlueDevil Pro on August 24, 2020 at 8:20 am

        Michael-

        Thank you for asking about your Cadillac Deville. After the 50 minute idle, you would shut the vehicle off and allow it to cool down for a couple of hours. It is important that the vehicle just sit there and idle for the 50 minute run. You wouldn’t want to drive it and put extra compression in the system. The product needs a clean, free-flowing system in order to get the benefit of using it.

        Thank you!

What should I do? I spent 40 bucks, followed your directions, and now I’m out 40 bucks and my car is still not fixed. Is there any possible way you could give me another pour n go bottle with directions that will fix my leak? I am unemployed and can’t afford another bottle of pour and go.

    Very confused. 2000 Ford Explorer 4.0 V6 OHV. I had a head gasket leak causing a rough idle/misfire and bubbling coolant reservoir but no smoke. I used blue devil after flushing the system twice with Prestone flush and followed the directions to a tee. Rough idle and misfire has ceased, but now there is thick smell of burning coolant and exhaust is smoking now like typical blown head gasket… I guess one step forward and two backwards… Will this resolve after a little while?

  14. Dennis with overheating 3.7 Jeep on July 11, 2014 at 10:12 pm

    Above idle my Jeep Commander overheats. To eliminate the possibility of a warped head, I removed the top hose and added “Pour-N-Go” per directions on bottle. The temperture gauge stayed 3/4 toward hot during the 50 minute idle period. After that, with transmission still in park, I reved the engine to 2,500 – 3,000 RPM. The gauge quickly pegged all the way to hot. I do have a small radiator leak, but I made sure anti-freeze level didn’t get low. Would that leak prevent the Blue Devil from working, or is something besides a head problem causing my overheating?

    • BlueDevil Pro on July 15, 2014 at 3:40 pm

    • BlueDevil Pro on September 18, 2014 at 1:39 pm

      Don-

      Yes, you would need to use two bottles of the “Pour N Go” to treat your V-8 Dodge. In addition to the directions, you will want to change the oil before and after the BlueDevil process.

      Instead of pouring the product through the reservoir/overflow, with the car off and engine cold, you may add the product through the top radiator hose. Once it has been added reconnect the hose and start the idle from that point.

      Yes, the BlueDevil “Pour N Go” Head Gasket Sealer will work for you. Based on your symptoms you will want to change your oil before and after the BlueDevil process to ensure proper results.

    Hi i have 99′ GMC YUKON I WAS TOLD I HAVE A BLOWN HEAD GASKET……I HAVE READ THE DIRECTIONS ,, AND FOR THE RADIATOR FLUSH ….DO I DISCONNECT THE END OF THE HOSE THATS CONNECTED TO THE RADIATOR….OR THE END THATS ON THE MOTOR??,,, AND IVE SEEN OTHER COMMENTS CONCERNING CHANGING THE MOTOR OIL …..IS THIS ALSO PART OF THE PROCEDURE ??

    • BlueDevil Pro on October 27, 2014 at 2:04 pm

      Stacy-

      You may add the flush directly through the radiator cap, if your vehicle has one. If the vehicle only has a reservoir, then you may add the flush the the top radiator hose (where it connects to the radiator).

      If you notice any milkiness or signs of water/antifreeze in your motor oil then we strongly recommend changing the oil before and after the BlueDevil Head Gasket Sealer process.

        What if I already poured blue devil into the reservoir. Will it still work ?

        • BlueDevil Pro on July 9, 2018 at 9:07 am

          Tim-

          You wouldn’t want to add the product in through the reservoir because, as per the directions, you are to add the product to the system when the engine is cold. Water/coolant is only being pulled from the reservoir as needed, so it may not have pulled into the system until the engine was hot. Are you still noticing the same symptoms?

  21. Benjamin on December 13, 2014 at 4:04 am

    I used the mechanic approved blue devil head gasket sealer and it worked very well. I only used 16 fl oz per the instructions and still have half the bottle left. A few weeks later i think i may have a small leak again. I would like to use the rest of the bottle for a second treatment, but I don’t feel like doing radiator flush for my system again. Since I already did this flush a few weeks ago is it necessary for me to do this again? Can I just remove my thermostat and add blue devil? Also since i already replaced my thermostat with a brand new one after the first treatment could I re-install this one after the second treatment?

    Could I also use the pour N go version after having treated with the mechanic approved product the first time?

    I own a 2004 v6 3.0 Jaguar s type

    Thanks

    • BlueDevil Pro on December 16, 2014 at 2:06 pm

      Benjamin-

      You will still want to flush the system prior to adding a 2nd application to ensure proper results. You will again remove the thermostat for the idling, with BlueDevil, and then you may re-install that thermostat once the idle is complete and the engine has cooled down.

      If you decide to use the “Pour N Go” then you would not have to flush the system or remove the thermostat prior to use.

        I used your Blue Devil pour and go about follow instructions and said to let it run for 50 minutes at idle wish I did and also said to let engine cool for 2 hours after would it be better to let vehicle set all night

      The 16 ounce BlueDevil “Pour N Go” Head Gasket Sealer does not require you to remove the thermostat; it is an easy-to-use product. You can simply drain enough antifreeze so that you can pour the BlueDevil in.

  23. Calvin on March 18, 2015 at 12:28 pm

    Is this product safe for oil? I have freeze plugs that are leaking, and the geniuses who designed this engine decided to put the freeze plugs in the same chamber as the timing chain where oil is at. Needless to say, there is a relatively low concentration of coolant with the oil, but the oil is leaking because there is a crack in the oil pan. Anyway, will this product seal my freeze plugs if there is hot oil running on the freeze plug all the time, or do I have to do this fix with a DIY solution?

    • BlueDevil Pro on March 18, 2015 at 12:42 pm

    Hello my name is Tyler, i have a 2005 subaru impreza wrx H4 2.0. when im trying to hit into my boost hard around 4rpm. My car starts to jump, but im pretty sure i know why with that. But my car it running rich, i dont have smoke coming out of the exhuast or a wet drip. But i do have a small bit of coolant in my oil. An my oil cap has a milky look too it. I also keep using oil fast. Could all of this have to do with a head gasket problem???? Or should i say f**k it and buy new trans and motor.

    • BlueDevil Pro on June 16, 2015 at 6:59 pm

      Tyler,

      Thanks for your question about your WRX. They are great cars and a lot of fun to drive, but they are known to blow head gaskets especially if you drive them hard. Turbo cars in generally use more oil than naturally aspirated cars so your oil consumption might not be unusual. As for the coolant in your oil, that’s a good indication that you have blown head gasket even if you don’t have white smoke from the exhaust. BlueDevil Head Gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/) is guaranteed to seal your head gasket leak and get you more life out of your car.

      The jumping could be related to the blown head gasket, but it may also be in indication that your O2 sensor has gone bad, you need new spark plugs or have other fuel system problems. You might also try BlueDevil Fuel System Cleaner to make sure you don’t have any carbon build up from running rich and that your injectors are firing properly. You can pick up BlueDevil Fuel System Cleaner here: http://store.gobdp.com/fuel-system-cleaner-00202/

The next morning I put water and started it up and noticed it was losing water. At first I thought it might be the hose underneath but I replaced it and it still leaking water. I have no water in the oil or transmission fluid do u think your product can help my car form leaking the water I’m 80% positive i messed up a head gasket.

    Hi. I have a 2002 Honda Civic EX 1.7L that Honda dealership diagnosed with a hairline crack in the head gasket. I used Blue Devil Pour N Go and it seemed to work great… for 2 days… now I’m losing coolant at the back of the engine near the driver’s side door. I’m fairly certain it’s my water pump that Honda actually replaced just 13 months ago (so of course it’s out of warranty by 1 month!). I’m going to have the water pump replaced again tomorrow, my concern is when the mechanic flushes the cooling system will it also remove the Blue Devil from the head gasket effectively putting me right back to square one with the added little bonus of having to fork out $300+ on another water pump?

      YaYa,

      Thanks for your question about your Chevy Impala. It sounds like BlueDevil Pour-N-Go fixed your head gasket leak as you don’t have the white smoke anymore. Your car not starting may be due to another problem. Since you had a blown head gasket, you may consider changing your engine oil and spark plugs as they oil may be contaminated with coolant and your spark plugs may have gotten fouled by the coolant in the combustion chamber. These problems may also be the reason for your car not starting now.

      Thanks again for your question!

    Hi,

    So I bought Blue Devil 32 oz that requires me to remove my thermostat. I think it would be difficult for me to take out my Mazda 6 2004 and my question is what is the effect if I don’t remove thermostat and use the fluid anyway? Will it work? Will the fluid make any damage to the thermostat? What are the chances that it will go wrong? I believe 32 oz is a lot better than the 16 oz according to my researches from other users but the problem it would cost me more to have a mechanic remove the thermostat.
    Best regards,

    • BlueDevil Pro on September 10, 2015 at 9:48 am

      Long-

      For best results, we strongly recommend removing the thermostat to ensure free flow. The chances of BlueDevil working properly would decrease if all of the directions are not followed exactly, including the removal of your thermostat.

      Rod-
      You may use either Head Gasket Sealer. The “Pour N Go” (16 oz./white label) is a less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (32 oz./yellow label) requires both the removal of thermostat and a flush before applying the product; the 32 ounce is the more concentrated formula.

      The product with the yellow label will give you best overall results as long as you can remove the thermostat and flush the system prior to use. However, if the thermostat is difficult to remove or you would rather not then you can always use the “Pour N Go”. With the use of either product, be sure to follow the guidelines for the proper amount to use. Based on your capacity, you will be using 16 ounces either way (if using Pour-N-Go you would need 2 full bottles).

      The product should be poured directly into the radiator when adding it. Even if the outside temperature is hot we still recommend running your heater on max during the 50 minute idle. Once the 50 minute idle is complete you should shut the engine off and allow it to cool for at least 2 hours. The seal created by BlueDevil is permanent and you should not have to reapply the product at any time.

    Dear Blue Devil,
    My mechanic said that my 6 cycl 1993 camry xle had a had a blown head gasket and given the age/mileage of the car, it didn’t make sense to spend the money to replace the head gasket. He suggested junking the car.
    I bought a bottle of Blue Devil Pour and Go. I followed the instructions on the bottle….The instructions say to slowly pour the Blue Devil into the radiator, (starting with a cold engine)…then turn the heat on full and idle for 50 minutes. I took 2 minutes to pour the BD into the radiator, I turned the heat on full….After 30 minutes the engine temperature instrument showed the engine was HOT so I had to turn off the car. The overflow resevoir was boiling. While the car was idling, it looked like gases were being pumped into the overflow resevoir. Also, I noticed that while the heater was on full, it was not hot. Please provide direction on where I should go from here. I’m on my own, my mechanic went of business last week so I can’t rely on him to help.
    Thanks,
    Mark

    • BlueDevil Pro on October 22, 2015 at 4:59 pm

      Mark,

      Thanks for your question about your Camry. There are two possibilities. First, you may not have enough coolant in your system to properly cover the leak or allow your heater to work. We would recommend filling your cooling system all the way up with coolant to make sure your car doesn’t overheat and BlueDevil is properly circulated all the way through your system to seal the leak. If your car cooling system is full and your car still overheats before the 50 minute idling period has passed your head gasket leak may be big enough to require BlueDevil Head gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/) which includes a radiator flush and removing your thermostat while you’re sealing the leak.

      Thanks again for your question!

    Ok,i have a saturn sc2 2001, the first time i tried blue devil it did not work and my exauhst continued to spew white smoke. I also did not drain my coolant prior to applying the blue devil which leads me to believe that it did not get into the radiator, i poured the blue devil into my reservoir originally, and i noticed that after idling for 50 mins it was all still there. Do you have any tips on something i cld try different this second time im gonna use it? Ex. Removing thermostat prior to application,emptying coolant prior,etc…

    • BlueDevil Pro on October 16, 2015 at 9:35 am

      David-

      Thank you for asking about your Saturn. It is important that the product be poured directly into the radiator. There is no guarantee that the product would actually pull from your reservoir during that 50 minute idle to actually circulate and be able to seal, which sounds like what happened with your application. If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there. Once it has been added reconnect the hose and start the idle from that point.
      Flushing the cooling system and removing the thermostat, prior to using the product, would also give you an additional benefit. Doing this process in a clean, free-flowing system, will give the product the best chance of circulating correctly and give you the best overall chance of seeing good results.

      Thank you!

    • BlueDevil Pro on October 16, 2015 at 9:14 am

      Courtney-

      Thank you for your question. After the 50 minute idle, go ahead and shut the vehicle off and let it cool down for a couple of hours (at least 2 hours). At that point, you would be able to take your BMW for a test drive and see the results you got.

    I have a 2001 VW Jetta, almost a year ago had the water pump replaced (overheating). Still overheated used the pour and go blue devil. Car stopped overheating. Last week had to replace the water pump again. But its still overheating. Since I replaced the water pump do I need to use blue devil again?

    • BlueDevil Pro on October 27, 2015 at 3:47 pm

      Jaime-

      There are many different things that can cause an engine to overheat. When a vehicle is overheating it doesn’t always mean that it has a blown head gasket. Please contact us at 888-863-0426 so that we may discuss your VW in more detail and give you the best recommendation based on all of its symptoms.

    I have a 2002 Jeep Grand Cherokee Limited. V8 with a 4.7 cylinder. The thermostat used in my car is what creates the seal from thermostat housing to the engine block, the gasket is built into the thermostat. Without the thermostat in, coolant would leak right through the connecting point. Is there any way to run the head gasket sealant where the thermostat in as long as its open?

    • BlueDevil Pro on October 29, 2015 at 1:24 pm

      Dan-

      The way you can get around the thermostat with a housing is by taking the thermostat and modifying it so that the middle piece does not close; you may remove this piece or gut the middle of the thermostat. By doing so you will create a free flow and still be able to have the full housing installed. Once the process is complete you will need to replace the thermostat.

      Thank you!

      Sabrina-

      Thank you for your question. If you have water/coolant in the oil, you would want to change the oil before and after the BlueDevil process, regardless of whether you are using the Head Gasket Sealer (32 oz yellow label) or the Pour-N-Go Head Gasket Sealer. Operating your vehicle with water/coolant in the motor oil for extended periods of time can and will cause further damage to the engine.

  50. Joel on February 1, 2016 at 8:23 pm

    HI I purchased the pour n go blue devil head gasket sealer…my jeep overheated before the 50 min idle had elapsed..east gasses pushed out into the overflow. If it starts overheating should it be shut down and wait till cool and then continue with the rest of the 50min or let it idle for the full 50 min??

    • BlueDevil Pro on February 2, 2016 at 10:38 am

      Joel-

      If the vehicle begins to overheat within the 50 minute idle you would want to shut it down to prevent harm to the engine.

      You had mentioned that the vehicle may be getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly. Be sure to follow the guidelines for the proper amount to use based on the size of your cooling capacity.

        That makes sense but have you ever heard an engine run without a sparkplug in a cylinder? It sounds like the engine is going to rip itself apart. I shut my jeep off and let it cool down then I fired her up again and left it idle for about another 15-20 started to heat up. Shut it down…was nervous but heck it didn’t climb above the 2 in 210 on my way home wich is a little over a half an hr drive. So fingers crossed. Going to test it again today.

    • BlueDevil Pro on February 11, 2016 at 8:41 am

      Tony-

      Thank you for asking about your Ford Explorer. If you have water/coolant in the oil, we would recommend changing the oil first before starting the BlueDevil process. You would also want to do a second oil change after the process was complete, as the product would not instantaneously seal and you would still get a little water/coolant in the oil during the 50 minute idle. Feel free to contact our technical support line at 888-863-0426 with any other questions.

    I don’ think I will be able to add the pour and go solution to the radiator, because some of the coolant is going back into the reservoir when I idle too long. Once this happens the remaining coolant does circulate though. Can I remove the thermostat housing and pour directly into the block as long as there is coolant in there. Thanks. 1999 Ford Ranger

    • BlueDevil Pro on March 9, 2016 at 10:51 am

      If you have an issue with removing the thermostat, you can use the BlueDevil Pour-N-Go Head Gasket Sealer, which has a slightly less concentrated formula than the Head Gasket Sealer (32oz yellow label) and would not require the removal of the thermostat. Keep in mind, you would need 2 bottles of the Pour-N-Go Head Gasket Sealer for your V-8 Northstar engine. Feel free to contact our technical support team with any other questions.

    Is there any continuing sealing benefit from the Pour N Go remaining in the system, or does it’s leak sealing properties stop after the initial 50 minute idle and 2 hour cure cycle?

    • BlueDevil Pro on April 18, 2016 at 9:09 am

      Logan-

      The product only reacts to heat one time, so after a complete heat cycle (heat up and cool down) it is no longer active. The product is only sealing during the initial 50 minute idle. After the vehicle cools, any extra BlueDevil in the system would be like water, it’s not going to continue to react or continue to seal.

        I have spent the better part of six months tracing an intermittent leak in my 1.6L 16v Suzuki Sidekick to include UV dye, pressurized leak tests, and replacing the water pump and head gasket all with no luck. This lead me to believe I was looking at a crack or warping. I tried the Pour and Go as a last ditch attempt… and although it only been a week, I have not lost a drop of antifreeze yet! Usually I would be ~ 1-2 cups low.

    • BlueDevil Pro on May 2, 2016 at 11:14 am

      Ol’McDonald-

      Based on your description, unfortunately, the leak you have or symptoms you are having may be a little too extreme for what the product is intended for. In order to get the full benefit of the product, the vehicle would need to be able to idle for a full 50 minutes without overheating or stalling out, and you shouldn’t be losing more than about a quart of water/coolant. A hard part repair may be your best option.

    I have Marne Inboard diesel, closed coolant system cooled by a tubed heat exchanger. I’m losing coolant and have a lot of white smoke in the exhaust but only at mid to high rpm. I changed head gasket and had head checked by machine shop but still same white smoke and loss of coolant . Trying blue devil but concerned runs cold at idle with no thermostat and coolant only leaks into exhaust at higher rpm. Is it important to only run for 50 minutes and no longer ? Can I run on load at high rpm ? Even on along run under power without thermostat barely reached 150 ‘. Should I replace thermostat but not use antifreeze to allow longer time for blue devil to find and seal the leak?

    • BlueDevil Pro on June 29, 2016 at 8:25 am

      David-

      Thank you for asking about your Marine Inboard Diesel. Based on your description, we recommend using the BlueDevil Pour-N-Go Head Gasket Sealer. The product will react at a temperature of about 150 degrees Fahrenheit. If you are noticing it is not really getting up to that temperature during the 50 minute idle, you can slightly increase the rpm and/or let it idle for longer than the 50 minutes required. 50 minutes is the minimum the engine would need to run in order to achieve proper results.

    • BlueDevil Pro on July 19, 2016 at 4:07 pm

      Chris-

      Due to the capacity of your cooling system we recommend using the 32 ounce BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/).

      It sounds like the vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak (possibly #7); this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.

      Thank you for asking about your Dodge Durango.   You may use either Head Gasket Sealer.  The “Pour N Go” (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) is a less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use.  Whereas the “Mechanic Approved” (http://store.gobdp.com/head-gasket-sealer-38386/) requires both the removal of thermostat and a flush before applying the product; the 32 ounce is the more concentrated formula. 
        The product with the yellow label will give you best overall results as long as you can remove the thermostat and flush the system prior to use.  However, if the thermostat is difficult to remove or you would rather not then you can always use the “Pour N Go”.  With the use of either product, be sure to follow the guidelines for the proper amount to use.  You will need two Pour-N-Go Bottles to properly treat your Dodge.

  65. William Abrams on January 28, 2017 at 7:45 am

    I used the Yellow Label Head Gasket Sealer 32oz on my 2004 Dodge Ram 4.7L V8 about 2 years ago. The product worked great up until 6 months ago. I started getting rough starts and misfire codes on cylinders 1, 3, and 5 and am getting bubbles in my coolant. So I redid the whole process as I did before. I removed my thermostat, flushed system with water, then used 2x containers of Bluedevil Flush. Drove truck around for a couple days to get it super clean. Drained, flushed with water again and did the Bluedevil Yellow Label with 50 minute idle just as before. Unfortunately I don’t believe it completely sealed those cylinders because I am still getting bubbles on my system.

    So here is some information along with my question:
    Now I read on some of your other comments that I should remove the spark plug from the cylinder with this type of problem to eliminate the pressure. I didn’t do this as I have 3 cylinders leaking. My truck, during the 50 minute idle, never got above 105 degrees F. The bluedevil and distilled water mixture is still in my system. Since my truck didn’t get all the way warmed up, could the bluedevil in my system still be good and able to seal my leaks if I remove says 1 spark plug at a time and idle for about 20 minutes on each cylinder with the plugs removed?

    Sorry for the long message. I am just looking to avoid changing the head gasket until spring time here in NY. I appreciate your prompt reply as I have to get antifreeze back into my system today. It will be falling below freezing temperatures by tonight. Thank you.

    • BlueDevil Pro on January 30, 2017 at 10:58 am

      William-

      Thank you for asking about your Dodge Ram and for all of the detail you have provided. Based on your description, we would recommend having a compression test performed. Which ever cylinder is reading with the lowest pressure, that is the plug you would want to pull and leave our for the entire 50 minute idle. The product will react at a temperature of around 150 degrees Fahrenheit, so it does not sound like the product has reacted yet, being that the temperature only got to around 105 degrees Fahrenheit. During the 50 minute idle, in addition to the directions and spark plug removal, you may want to rev the engine up a bit during the idle to ensure it can get up to temperature.

    I have a 3.4 V-6 4Runner with 217,000 miles. In the past year when starting up on a cold engine it has a rough idle, on occasion it will blow out a lot of white steam until it is warm (it isn’t normal for this part of the country). It uses some antifreeze also but not much. When it warms up and the thermostat opens up I have no more problems until next time I start it when cold. I am leaking antifreeze into the exhaust and I think this is why it idles rough, just not enough to make steam. Sometimes it leaks more and a lot of steam. Would this BlueDevil Head Gasket Sealer help? (Also, I have checked and changed MAF, O2, vacuum lines, fuel injectors, coil packs, etc so this is the last thing I have to check.

      Thank you for asking about your Toyota 4-Runner. Based on your description, you would be a great candidate for the BlueDevil Pour-N-Go Head Gasket Sealer. It is possible that you are getting combustion/exhaust gases pumping back into the cooling system. You can use a “Block Dye Tester” to confirm whether or not that is the case.
      BlueDevil will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.

      Thank you!

        Ok, I tried this a few weeks ago, followed instructions and also pulled #3 sparkplug, let run for 50 minutes, sounded horrible as expected with a plug missing. Afterwards I put sparkplug back in, new thermostat, and antifreeze. I have been driving it and no more problem, works great as of now! Looks like this problem is resolved. THANK YOU BLUEDEVIL!

          John-

          That is excellent to hear! Once the product seals it would be a permanent seal, so you should be good to go at this point. We appreciate your wonderful feedback!

          Thank you!

    Hi, I have a 2003 Honda civic. I’m going to try the pour-n-go. My question is.. do you have to leave the heater on max after pouring the product and leaving the heater on max while doing the 50mins idle?

    • BlueDevil Pro on August 8, 2017 at 8:38 am

      Franco-

      The heater should remain on the maximum setting during the entire 50 minute idle.

      Thank you!

      Matt-

      Thank you for asking about your Jeep Liberty. If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there; do not pour it into the reservoir. Once it has been added reconnect the hose and start the idle from that point.
      Based on your description, It sounds like you may be getting combustion/exhaust gases blowing into the cooling system and creating pressure.  We recommend applying BlueDevil Head Gasket Sealer to remedy the problem.  To give yourself the best overall chance of BlueDevil working successfully is to remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave the plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.
      As per the directions, you will be removing the thermostat and flushing the cooling system prior to product use. Feel free to contact our technical support team at 888-863-0426 with any other questions.

      Thank you!

    I have a 2001 Pontiac Montana, I orderd the 32 OZ bluedevil from ebay. I have had occasional overheating for about a year. I couls not find a leak so I figured it was some sort of head gasket problem. I was drivibg on the highway and the Van got really hot. I oushed it into the red trying to get off the highway. SInce then when I first reloaded the coolant at a 7-Eleven after the overheat I still have clean oil. One trip to town and back again it over heated. Now I have slight white smoke and my oil is contaminated looks like chocolate milk.

    My question is, that you recoment pulling the thermostat but in this model that can not be done without pulling the throttle body off. A good bit of work and a new gasket is required. Once you get to the thermostat the gaslet is a rupper O-Ring on the thermostat so there is no gasket to seal it if you remove the thermostat. Also I feel I would have to ad water while I try to run the car for 50 minutes and the reservoir does not seem to draw the fluid in. The system does not bleed so I know I am getting air into the coolant.

    What do advise me about the problems I am seeing in using this product?

      Scott-

      Thank you for asking about your Pontiac Montana. If removing the thermostat would be an issue for you, we recommend using the BlueDevil Pour-N-Go Head Gasket Sealer (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/). The product is an easy, do it yourself version of our 32 oz. bottle and does not require the removal of the thermostat. The product is intended for use in 4 or 6 cylinder engines, so be sure to use the proper amount of the product.
      You would not be able to add any water/coolant during the 50 minute idle. The system should be almost at capacity before starting the process, leaving just enough room for the recommended amount of the product. In order to get the benefit of using the product, the vehicle would need to be able to idle for a full 50 minutes without overheating or stalling out, and you shouldn’t be losing more than about a quart of water/coolant during that 50 minutes. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

    I was having problems with my 2004 Nissan Altima. A trusted mechanic worked on my car and the last thing he did was pour the BlueDevil Radiator and Block Sealer. He followed the directions and even let the car sit over night. Flushed everything out and did a oil change. Car runs fine, but now there is quite a bit of white smoke coming out of the exhaust. could that be due to the car smoking out the BlueDevil ?

    • BlueDevil Pro on December 11, 2017 at 3:21 pm

      M.-

      Thank you for asking about your Nissan Altima. What were the symptoms the mechanic was originally trying to treat? The BlueDevil Radiator & Block Sealer is specifically formulated for seeping or lightly dripping leaks from the radiator and/or the block. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

      Thank you!

    I have a 2000 Cadillac DeVille I just put brand new radiator thermostat and water pump in it just find out my head gasket is about to go. I used the pour and go and put it in the reservoir since I don’t know where the radiator hoes was my car is know for running hot so after 20 minutes if idol it turned off should I let it cool off than idol more? Did i just waste my money putting it into the reservoir?

    • BlueDevil Pro on February 12, 2018 at 10:59 am

      Shasta-

      Thank you for asking about your Cadillac Deville. The BlueDevil Pour-N-Go Head Gasket Sealer (https://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) is intended for use in 4 or 6 cylinder engines, so it would not have been enough product to properly treat your Northstar V-8. Also, it is very important that the product be poured directly into the cooling system, and not through a reservoir/overflow tank. Water/coolant does not pull from the reservoir/overflow right away, in fact, it probably is not pulling until the engine is hot, which would essentially be like adding the product when the engine is hot. Please contact our technical support line at 888-863-0426 for further assistance.

      Thank you!

        I have a land rover 2001, doesnt have a radiator cap, should i pour it by the top hose that goes straight to the engine?

        • BlueDevil Pro on February 14, 2018 at 8:26 am

          Armando-

          Thank you for asking about your Land Rover. Yes, that would be acceptable. If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there; do not pour it into the reservoir. It may be added into the hose or the opening on the radiator. Once BlueDevil has been added, reconnect the hose and start the idle from that point.

          Thank you!

    I have W124 Mercedes diesel and coolant is leaking from a freeze plug. Can Blue Devil seal that leak ? Thanks

  76. Chris on July 11, 2018 at 4:07 am

    I have a 92 C2500 with a 350 small block the head gasket on bank 2 is blown I can visually see the leak and white smoke from the rear now I know this is recommended for 4 or 6 cylinder but can this work on mine as well or is there different quantity or something I need to use?

    • BlueDevil Pro on July 11, 2018 at 9:22 am

      Chris-

      You may use either Head Gasket Sealer to retreat the vehicle. The “Pour N Go” (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) is a less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (http://store.gobdp.com/head-gasket-sealer-38386/) requires both the removal of thermostat and a flush before applying the product; the 32 ounce is the more concentrated formula.
      The product with the yellow label will give you best overall results as long as you can remove the thermostat and flush the system prior to use. However, if the thermostat is difficult to remove or you would rather not then you can still use the “Pour N Go”. With the use of either product, be sure to follow the guidelines for the proper amount to use. Based on your capacity, you will be using 32 ounces either way.

      Thank you!
