    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.

        • BlueDevil Pro on July 8, 2015 at 9:59 am

          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.

          Thanks!

            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.

          • MTT on February 6, 2021 at 10:49 am

            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.

            Thank you!

            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!

        • Trenton Lumpkin on July 31, 2020 at 12:44 pm

          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.

        • BlueDevil Pro on April 14, 2016 at 12:04 pm

          William-

          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.

          • BlueDevil Pro on August 23, 2021 at 8:19 am

            Nino-

            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 M Pierce on November 23, 2021 at 11:58 am

            Top radiator hose for it slowly, if it doesn’t accept it you may have to make sure your reservoir box is low enough ?.

            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.

            Amy-

            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.

          • Deforest Cooper on October 15, 2022 at 3:35 pm

            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. They are not intended to be used simultaneously. Please contact our technical support line at 888-863-0426 with any questions.

          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.

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.

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

          Thank you for asking about your Dodge Charger.

          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

          John-

          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 July 17, 2023 at 8:56 am

            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.

        Feel free to contact us at 888-863-0426 with any questions.

      • BlueDevil Pro on February 13, 2017 at 10:19 am

        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.

        Thank you!

      • BlueDevil Pro on November 27, 2017 at 10:52 am

        Jeff-

        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!

  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.

        • BlueDevil Pro on February 29, 2016 at 2:31 pm

          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 live in las vegas just recently bought a 1999 chevy suv k1500 4×4 at an auction. it was posted on the windshield that there was oil in the water. 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!

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.

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

      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.

          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? Feel free to contact our technical support line at 888-863-0426 if you have any questions.

          Thank you!

      Sir-

      There are a number of reasons your vehicle may be overheating. We have previously posted an article about this exact situation, it can be seen here: https://gobdp.com/blog/car-overheating/

      Once you have had a chance to further diagnose why your vehicle is overheating you will be able to better attack the problem at hand.

    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

      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

        • BlueDevil Pro on August 12, 2019 at 9:45 am

          Ronald-

          Letting the vehicle cool for 2 hours after the 50 minute idle would be sufficient. It doesn’t have to set overnight.

          Thank you!

    I have an 1987 ford f150..it has milky oil and white smoke…i have the 16 oz. blue devil sealer. Do i have to remove the thermostar or can i just drain the antifreze and go from there?

    • BlueDevil Pro on March 10, 2015 at 2:43 pm

      Steele-

      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.

      Thank You!

    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

      Calvin-

      The Head Gasket Sealer should never be added to engine oil. Unfortunately, we do not manufacture a product that will help you out in this instance.

      All the Best!
