Where is My Car Coolant Going?

car coolantHopefully, your car coolant is going where it should be, through your engine!  The purpose of your engine’s cooling system is just that, to keep it cool so hopefully your coolant is taking the journey from your engine to your radiator and back again while you drive.  If your car coolant is headed somewhere else, then you’ve got a problem.  Cooling system problems usually show up as either an overheating engine, or a leaking engine either in the form of drips and puddles or steam from under your hood.

To understand where your car coolant is going, it’s important to understand it’s path through the cooling system so you know where to look for leaks or check for other problems if your car is overheating.  Your coolant actually takes 2 possible routes depending on the temperature it’s at.  When your engine is cold (usually below 180 degrees) the water pump pushes coolant through the engine where it is warmed, up through a hose to your vehicle’s heater core, then back through another hose into the water pump to make the trip again.

If your coolant is hot from its trip through the engine it will cause the thermostat to open allowing some of the hot coolant to travel a different rout out through the radiator at the front of your vehicle where it will be cooled back down before it heads back to the engine block.  The hotter things get in the engine, the further the thermostat will open to allow more coolant to flow out to the radiator and be cooled.

In identifying the different routes of coolant in your car start by locating the radiator.  It will be just in front of your engine often with an electric fan attached to it.  The radiator will have two large hoses, about 2 inches in diameter, attached to the sides or top and bottom.  One hose usually leads to the thermostat while the other will lead to the water pump.  The other path your car coolant takes, through the heater core is best found starting at the firewall.  Your heater core is a small radiator inside the cabin of your vehicle in the ventilation system.  Hot coolant is carried to it through the firewall in hoses.  They usually are on the passenger side of the engine compartment.  These hoses will be smaller 1 to 1 ½ inches in diameter and one will run to the radiator while the other will run to the engine block or cylinder head.

Once you’ve located all these components and hoses, start your vehicle’s engine and allow it to warm up watching all of these components for signs of a leak like steam or drips.

If you discover your leak is coming from the end of one of the hoses in your engine it may be time to replace the hose.  If it is swollen and appears too big for the end connection, has cracks, rips or tears it is time to replace that hose.  If you discover your leak coming from another location use BlueDevil Pour-N-Go to seal your leaks.  BlueDevil Pour-N-Go is a specially formulated to seal the leaks in your cooling system without damaging or harming any other equipment.  BlueDevil Pour-N-Go is a non-particulate sealer that reacts to the temperature differential created at the leak point.  BlueDevil Pour-N-Go is safe to circulate in your cooling system and will only activate at the leak point bonding to metal or plastic.

  2. I have/ had a slow head gasket leak in my 2002 Dodge Stratus. Since I recently put in new thermostat, new water pump, water terminal, and a part called an activant I was shocked that this summer became a nightmare. I had my mechanic use the Blue Devil treatment less than 48 hours ago. I have no more savings and on social security and can’t afford a car payment. I drove it this am to a couple of necessary stops maybe going 8 miles. It was hot outside and I did not run ac. All I noticed is a drop of liquid had come out of the front left section. This was about the size of a nickel. Is that normal? Please advise as this is my last resort for my former independence and I am only 64. Thanks!

    1. I have a nineteen minty nine Pontiac grand Prix put head gasket sealant in three months ago and had to put antifreeze in it ever since now the oil is a light brown in color and white exhaust is coming out of tail pipe did my sealant broke and antifreeze is going into my oil miss Linda going crazy

      1. Linda-

        Thank you for asking about your Pontiac Grand Prix. Which BlueDevil Head Gasket Sealer did you use? Are you saying that the product sealed up until now and water/coolant is starting to get back into the oil again or that it never completely sealed the leak? Please contact our technical support line at 888-863-0426 so that we may assist you with the warranty on the product and be able to make any appropriate recommendations.

  4. i have a 2000 malibu…i dont kniw where my coolant is going….the fan works…no leaks…on the ground…new water pump….new hoses…but my car still runs hot and the reservoir is empty all the time i need advice

    1. Camille-

      It sounds like you definitely have a leak in the cooling system, most likely from your head gasket(s). We recommend using 16 ounces of the BlueDevil Head Gasket Sealer to help stop your coolant loss and overheating.

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

      Thank You!

      1. I have an 06 Malibu doing the same thing. They have replaced hoses, head gaskets.. Basically the entire cooling system and I’m still losing coolant.. Would it be worth giving this a shot? I have put to much money into this car.

        1. Michelle,

          Thanks for your question about your Malibu. Mystery leaks like this can be elusive. To confirm that you have a blown head gasket you can purchase a chemical test kit from your local auto parts store to check for exhaust gases present in your coolant. You can also have a pressure test performed on your cooling system by your mechanic which would also help prove you have a blown head gasket.

          If either of these check positive we would recommend you using BlueDevil Head Gasket Sealer to seal the leak in your cooling system and get your car running back normally.

          Thanks again for your question!

      2. My name is Christopher, I purchased a used 2001 Chevrolet Malibu LS back in December of 2016 for myself & this car was parked at the end of my ma’s block with for sale signs on the Windows. It had at the time 174, something miles on it. Beautiful condition. I needed some wheels badly. I test drove it for a half hour drove awesome & yes still drive’s like a dream. Well; I have owned it for almost 5 months now & for the past 2 months it’s been costly buying engine coolant every few day’s. I have no leaks at all. Every morning I have to check my reservoir to make sure there’s coolant in the reservoir that’s a MUST. So therefore I have found out that it’s going through my engine, burning up & coming out of the tailpipe. I obviously do need to get a standard tuneup cause my car is also misfiring too. Yes I know the vehicle is 16 yrs old, but…if you keep them up & don’t beat on your vehicle’s they will last for quite sometime as well. Open to any comments or suggestions for my Malibu LS. Thank you for taking the time to read my car problems. Takecare.

        1. Christopher-

          Thank you for asking about your Chevrolet Malibu. Based on your description, 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. If that is the case, we recommend using the BlueDevil Head Gasket Sealer.
          BlueDevil Head Gasket Sealer 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.  Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

          Thank you!

      3. I put a sealer in my radiator called dike because I’m losing coolant in the reservoir and also White smoke is coming out of my tailpipe at startup .. this day number 2 seem like it’s not working if… If i wanted to put Blue Devil in there do I need to drain the system completely

        1. Wayne-

          Prior to adding the BlueDevil Head Gasket Sealer, you would want to drain and thoroughly flush the cooling system. Not knowing the chemical formulation used in your previous application, we would not recommend mixing the two. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

    2. I had a 1999 malibu and had blown a head gasket. So I replaced the engine and not even 2 years later boom another blown head gasket. Bad cars for intake manifold and head gaskets.

  5. Vinod here,
    I have Toyota Camry 1996 model, 4 cylinders, mysteriously loosing my engine coolant, I tried to see any leaking, dripping but could not see, went to my car Mechanic; he put pressure testing instruments on radiator inlet, keep almost one hour under pressure, there was no visible leak from cooling systems, coolant pump, hose, engine ! yet coolant is missing , after short drive ! Can you suggest how can I stop mysteriously loosing coolant, and getting my car overheated. Since long, I am passing this situation, l live in Chino, CA., hot enviroment all time in summer ! Please suggest me remeady .

    1. Vinod-

      Due to the fact that it is definitely losing coolant, there has to be a breach somewhere within the cooling system. We recommend using 16 ounces of the BlueDevil Head Gasket Sealer to help stop the coolant loss and get your vehicle back to running properly.

      Thank You!

  6. I have a 2005 chrysler pacifica i used some blue devil head gasket sealer. My hose was damaged and i lost some of the fluid. I am currently still losing water from somewhere. Do you think i should repeat the blue devil sealant or could my heater core be blocked?

    1. Mrs. Moore-

      We would like to get a little more detail as to the symptoms your Chrysler is experiencing and how long ago the BlueDevil was applied.

      1. I have a 2005 LaCrosse with a 3.8. I keep losing coolant as well with no leaks. The car runs at normal operating temperature while moving but when it idles for a few minutes after the motor has been running awhile it will start to overheat. I don’t have any noticible leaks. I have replaced the elbow tubes that connect to the tensioner and water pump from the block and replaced the thermostat with a fail safe one. I topped the radiator off and a few days later the coolant was gone. Will your product work for my issue? The oil is not milky nor do I smell hot coolant or notice any steam.

  7. My truck is using excessive coolant, I can see no leaking from any of the hoses involved. The truck does not overheat(yet) but I do see a small slow leak from the inner bottom corner of the radiator. What do need to do?

  8. I have a 05 Chrysler Pacific and had a transmission flush & every since I have to put antifreeze / water in coolant container smoking under hood .please help me why I’m I running out is it the radiator ?

    1. Cecilia,

      Thanks for your question about your Pacifica. It does sound like you have a coolant leak coming from somewhere under the hood. Our experience is that if you have a problem right after having maintenance done, they are often related. If you have a proper coolant flush they would have removed the transmission lines going to your radiator so our best guess would be that you have a leak there. If this is the case, our recommendation would be to take it back to the mechanic that did the work and see if they’ll replace your radiator as a courtesy.

      Thanks again for your question!

  10. I own a 99dodge intrepid es. It is starting to leak antifreeze. It’s like every 2 days I got to add antifreeze. I had it check. Hoses good. Radiator good. . from the reservoir the thermostat is working.
    Any idea what’s wrong or do u recommend blue devil?
    Please help.!!!!! Antifreeze is too expensive to buy like that.
    Oh I use the 50/50 antifreeze. Is that OK or do I need to do straight antifreeze? Help asap

    1. Dexter-

      Based on your description, we would recommend using the BlueDevil Head Gasket Sealer. As long as you are not losing coolant/water too quickly and the vehicle is able to maintain an idle for 50 minutes, without overheating or stalling out, then you should be able to see some great results from the product.

      Thank you!

  11. I drive a 2005 Nissan Murano .. this vehicle has been a champ.. I havent had one bit of trouble out of it since the day i bought it , But , I am now having to add coolant once a week .. Its not leaking . and I dont have a clue where its going .. My fan runs constantly , sometimes I have heat, sometimes I dont .. usually if I get up some speed I get heat.. My temp gauge is doing back flips.. But the car NEVER over heats.. I have had a new radiator and new hoses put on the car. I have had pressure test done.. I just dont understand what is going on with it .. Do you ?

    1. Travis,

      Thanks for your question about your Murano. Usually, mystery coolant leaks with no evidence combined with erratic temperature gauge readings are a pretty good indication of a blown head gasket. If your pressure test came back normal, it seems a little less likely but it could still be a very small leak. The last thing you could try is changing your thermostat and see if that gets things back to normal, but if not, we’d recommend trying BlueDevil Pour-N-Go to see if that can seal your mystery leak and get things back to normal.

      Thanks again for your question!

      1. I have an astra 1.7 cdti sri my car is losing coolant and now my car want start and also i dont know wer the coolant is going. And since my astra started losing but iv bin ading jus water . Can you tel me what the problem may be please.

        1. Muhammad,

          Thanks for your question about your Astra. If you’re loosing coolant and don’t know where it’s going it could be due to a blown head gasket as the coolant would be going into your engine. You also may simply have a slow leak, or a leak that only opens up when the system is warm so the coolant is evaporating before it leaves a drip or puddle on the ground. You could try testing your compression to see if you have a blown head gasket or adding UV dye to the coolant to help identify where the leak is. Once you’ve determined the source of the leak, you can use the appropriate BlueDevil leak stop additive to seal the leak.

          Thanks again for your question!

  12. My carr blows warms air and is about half way point while driving around town. But when i go 55-60 on the highway the temperature gauge sits at about a quarter and its cold outside. and since it got colder I’ve put in antifreeze in every other day it seems. Does this mean i need a thermostat?
    During the summer the temp gauge always sat at half mark.

    1. Kayla,

      Thanks for your question about your car. It does sound like you’ve got a bad thermostat that is staying open too much on the highway. It also sounds like you may have a decent leak as well since you’re adding so much antifreeze. If you haven’t had a cooling system flush recently, we would recommend performing a flush using BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/) when you replace your thermostat and add new coolant to make sure everything is operating at full efficiency. Also, before you replace your radiator, we would recommend checking your cooling system for leaks and replacing any old hoses.

  14. I am loosing coolant in my 2002 Ford Taurus 3.0 Vulcan engine. My reservoir tank was just filled about 3 weeks ago when I had my water pump replaced due to excessive coolant loss and smoking from by the water pump. Everything was fine until about 3 days ago. I do not see where any coolant is leaking. There are no spots on my garage floor but since filling my reservoir 3 weeks ago my tank has maybe an inch of coolant in it. It also started smoking really bad again by the water pump. It is white smoke and only does this when I turn my heat on. Car doesn’t overheat at all when heat is on or off. Any idea if your product would help or what my problem may be?

  15. I have an 2003 Ford explorer that keep loosing antifreeze with no leaks on the ground but has white smoke in front when opening the hood,

  16. hi i have a dodge neon 2005 sxt , 2.0 engine sohc that too seem to be loosing coolant misteriously. About a 1000 miles drive i add close to a half a gallon to a gallon per approx 1000 miles. I find also a smell of antifreeze i perceive slightly. The car does not overheat (stays from a quarter to less than half in the gauge all through trips and all and seems to be acting normally) so no overheat problems. Oil is normal colour , normal smell, etc. No white smoke but yet i seem to be loosing a bit of coolant like half gallon per 1000 miles. No visible leaks , where is it going??? could it be a bad cap? or is it a head gasket leak?? NOTE: i did notice that the main radiator hose was ‘inflated” loking like if it had air trapped or so, yet is not full of coolant, could it be that i need to purge it?? any advice on what to use? or what is going on? thanks

    1. Carlos,

      Thanks for your question about your Neon. If you do suspect a head gasket leak you can always check for that using a chemical test available at most auto parts stores that checks for the presence of exhaust gases in your coolant or by having a compression check done on each cylinder. For small leaks, you can also add UV dye to your coolant, drive for a few days, then park your car in a dark garage and search for traces of the UV dye in your engine bay.

      Since you mentioned you smell coolant it is possible that you have a leak in your heater core. That would allow coolant to leak into your ventilation system where it may drain out of your AC condensate drain where you most likely wouldn’t notice it.

      Thanks again for your question!

    1. Arturo-

      An easy way to check is to pull the dipstick if you notice a “milky” look to the oil then it most likely has water/antifreeze in the oil.

  20. My 1999 Malibu has a slow leak directly under the reservoir. The temperature never gets past the half way mark and the heater still works, but every other day the reservoir is empty. It seams like its loosing more fluid than the amount found by the leak. Should I change the thermostat? –

    1. Jeannie,

      Thanks for your question about your 99 Malibu. Great job keeping an eye on the temperature gauge and keeping your coolant reservoir full, that will help keep your car safe while you’re figuring out this problem. The leak you’re describing does sound like a pretty fast leak, but often coolant leaks look smaller than they really are because they leak the fastest when your car is warm and driving and the coolant often evaporates before you have a chance to check for evidence of a leak.

      You may try leaving your car running next time you get home from a longer drive and check for steam or for more fluid to help you pinpoint where the leak is coming from. Just be careful not to burn yourself and to stay clear of your engine’s fans.

      The problem you’re describing doesn’t sound like a problem with your thermostat since your vehicle’s temperature remains constant and it hasn’t overheated, we would recommend tracking down the leak first as it most likely is from a small hose somewhere near your coolant reservoir.

      Thanks again for your question!

  21. i have an 06 dodge grand caravan. my radiator stays empty and i don’t see a leak under the radiator. when i look the water is pouring from further back. i have to put water in it at least 3 times a day and once i put it in i watch it come out. where could the water be coming from because it leaks from right behind the motor.

    1. Faleisha-

      The amount of water/coolant that you are losing from your Dodge is more extreme than what our BlueDevil Head Gasket Sealer is intended to fix. The only way to fix a severe leak such as yours would be to replace/repair hard parts.

  23. I have a 2006 Malibu Maxx. Yesterday morning my low coolant light came on during my 45 min drive to work and later my lunch break was cut short as the gauge shot up to “HOT” and lights were blinking all over the place. Just had my oil changed and fluids topped off a month ago, and when i looked under the hood my antifreeze was gone, but i could not locate where it had gone to. Nothing dripping under the hood or under the car itself. I filled it back up with antifreeze and was able to drive about an hour or so last night, and this morning the gauge was creeping towards HOT after about 5 mins of driving, and my reservoir tank was almost empty already, had to fill it with another bottle of antifreeze. i don’t see leaks anywhere, but certainly could be happening when i’m driving and i don’t notice it.

    1. Tricia,

      Thanks for your question about your 2006 Chevy Malibu. Coolant leaks can be difficult to find because they are steam while your car is running. Based on how quickly you say your car is loosing coolant, it sounds like your leak is pretty large. Try checking for some other signs of a blown head gasket like milky colored oil, smoke from your trail pipe or bubbles in your radiator.

      To quickly find your leak, you can try adding UV dye to your coolant, then checking your car over at night with a black light to see where the leak is. You can find UV dye at most auto parts stores. When you find your leak, you can use the appropriate BlueDevil stop leak agent available here: http://store.gobdp.com/products/.

      Thanks again for your question!

  24. I have a 91′ Toyota Land Cruiser inline 6 4.0, about every month I’ll need to add about a half gallon of antifreeze to the radiator, but I can’t find where the leak is going. The oil is clear and definitely has been chemically tested and was told there were no chemicals of antifreeze in the oil, I have checked to see if the overflow container leaks, and everything else. No go, I installed a new thermostat myself, and gasket, but can’t find a leak anywhere. I checked all obvious places but under the block is bone dry. New radiator as well, it has got me wondering, is it possible the cooling system is leaking into the exhaust system and burning there? I haven’t seen any white smoke from the exhaust..could your product patch whatever leak I have going on?

    1. Braxton-

      Thank you for asking about your Toyota Land Cruiser. Although it does not seem you have any of the tell-tale signs of a blown head gasket, that fact that you are losing coolant would make you a good candidate for the BlueDevil Head Gasket Sealer. It’s possible that you are only losing coolant while the vehicle is in motion, explaining why you are not really seeing a leak. If water/coolant was leaking into the exhaust system, you would see white smoke coming from the exhaust pipe. Feel free to contact our technical support line at 888-863-0426 with any other questions.

  27. hi, i have toyota yaris sedan 2012 from saudi arabia. I mistakenly drained the radiator coolant and drive it for around 20 kilometers. While driving, i heard a little noise when pressing the pedal which sounds like metal to metal and the overheat warning light is on. I keep on driving and the car stopped. I started it again and drive another 5 kilomoters and the car stopped again. It was just the moment that i realized that i drained the radiator and when i check it, it was smoking upon opening the cap. After that, i fill the radiator full with coolant and i thought my problem was resolved. After 2 weeks of using my car again, the overheat sign was back. And upon observation, i was losing around 1 liter of coolant every time i drive 40-50 kilomters. Upon checking, there is no leak in the hose or everywhere. My question is, where the coolant is going? Thanks for d help

    1. Nico-

      Thank you for asking about your Toyota Yaris. From the sounds of it, when the vehicle was driven without water/coolant in the system, it overheated and unfortunately, may have blown the head gasket. Water/coolant getting in the oil or smoke coming from the exhaust pipe would be tell-tale signs of a blown head gasket, so it would be a good idea to start your search there. Another possibility could be that the water/coolant is getting back into your cylinder heads. If you are experiencing a rough idle or getting a misfire reading or code, that may be an indication as to where the coolant is going.
      As long as you are not losing water/coolant too quickly, and the vehicle can idle for a full 50 minutes without overheating or stalling out, you would be a good candidate for the BlueDevil Head Gasket Sealer, found here on our website: http://store.gobdp.com/head-gasket-sealer-38386/ .

  28. Hello I have a Chrysler Pacifica Everytime I pour antifreeze or water in it disappears and now im starting to see a slow water leak underneath the engine some where on the passenger side so I don’t know if it’s a hose or something else because you can’t see any bottom hoses so I was wanting to know would the blue devil product work if so which one I believe I have a v6 engine and it’s a 06 Pacifica . Thanks

  29. I have a 05 3.8L chysler Pacifica I keep losing my coolant I seem to have a water leak in the front of my radiater it continues to leak water, coolant what ever I put in it I called chysler they do not make that part I’m stuck what can I do

    1. Cindy-

      Thank you for asking about your Chrysler Pacifica. Based on your description, we recommend using the BlueDevil Radiator & Block Sealer, found here on our website: http://store.gobdp.com/radiator-block-sealer-00205/. As long as you are not losing more than about a quart of water/coolant during the 45 minute idle, you would be a great candidate for the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.

  30. I have a new 2014 Chevy Cruze 1.4l, I’ve noticed that over time it has slowly been losing coolant but I don’t see a leak anywhere, the leak is very slow. What should I do?

    1. John,

      Since your car is so new, you may consider taking it to a dealership to see if it is still under warranty. It’s not usual to slowly lose coolant due to evaporation in some vehicles so this may be what’s happening in your car. For very slow leaks like this, you may consider adding some UV dye to your coolant. After a few days of driving, you can park you car in a dark place and use a black light to look for traces of the dye around your cooling hoses, gaskets, block and radiator.

      Thanks again for your question!

  31. I have a 2002 Toyota Camry 4 cylinder engine. I recently started to loose coolant, however there is no visible leaks and signs that the coolant is being burned off through the tailpipe. The car has not overheated.

  32. i recently flushed my coolant and replaced it with coolant and distilled water but it didn’t take the amount it supposed to hold. It supposed to hold about 20 quarts which is roughly close to five gallons and it only took a little less than three gallons total (coolant/water) My truck is a F-150 2006, v8 4.6l

  33. I have a Volvo 850 1995 that I had sit for 3 weeks while I was on vacation before I left the thermostat had broke and was over heating until I pulled it out and now that I’m back the water reservoir is is empty everyday and I fill it up before I go but i don’t know where the water is going. There are no visible leaks.

    1. Eyver,

      Thanks for your question about your Volvo. Based on your question you could have quite a few different things going on. Our best guess is that you’ve got a coolant leak that only shows up once your system is hot and pressurized. Coolant that leaks while hot easily evaporates and can leave almost no trace of the leak.

      One thing we would recommend doing is adding UV dye to your engine coolant and driving for a few days. After a few days of driving, park your car in a dark garage and use a UV flashlight to search for evidence of your coolant leak around your engine bay and under your engine.

      Thanks again for your question!

  34. I noticed my coolent from my reserve is disappearing constantly leaving me to fill it up. I just flushed my radiator added to new hoses and changed the thermostat. The results are still the same with mulk now on my radiator cap. I also noticed a smell of gas, could be a blown casket or engine has rust and probably needs to be replaced. What you guys think? My engine is a 5.0 1994 chevrolet silverado 1500 with over 10010 miles. should I drop a new engine in or fix the problem?

    1. Frankie-

      Thank you for asking about your Chevrolet Silverado. 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; 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 system; you will need the full 32 ounce bottle for your Silverado.

  35. I have a 2004 Jeep Grand Cherokee. I am making payments on this car. I have had it maybe six months. I tried my heater and it hardly works. It will work then after awhile it will blow cold air. As I am driving I am hearing this knocking sound under my dash board. I noticed two weeks ago my Gauge was on and my thermostat stated 260. I was out of water. I haven’t put any water/cooliant in it since three months. It has always been full. Then two weeks later I noticed again, empty! I put more water in it. I did fill it up so when I cut off the car it made this gurgling sound! No leaks! I did have someone tell me it looked like some drops over my engine but, I am not certain. What can this be?

    1. Amy-

      Thank you for asking about your Jeep Grand Cherokee.

  37. Hi,

    I bought Nissan Pulsar N16 2005 car recently and noticed that there is water reduction in the reservoir tank. I removed the thermostat as well now it circulates all the time. I can see rust in the radiator.

    1. After running for 10-15 min I can see bubbles in the reservoir tank.
    2. After driving for more than one hour the water overflows in the reservoir tank and the system starts to overheat (sudden rise in the heater gauge)
    3. No engine miss at all, no oil in the radiator, no water in the oil tank.
    4. Pressure test in the radiator slight pressure loss after 15 min. But no visible coolent loss. Water level reduces by 50-100 ml.
    5. Cylinder Compression test all 4 cylinders around 110.

    Can this be a fault if radiator, water pump, head gasket or anything else ?

    Highly appreciate your advice.

    Thanks in advance.

    1. Dan-

      Thank you for asking about your Nissan Pulsar. Based on your description, it sounds like you may be experiencing a head gasket leak. You can use a “block-dye test” to confirm whether combustion/exhaust gases are getting into the cooling system. If the “block-dye test” does not show combustion/exhaust gases as being present, we recommend looking into having the water pump replaced. Feel free to contact our technical support line at 888-863-0426 with any other questions.

  38. I have a 2004 Grand Marquis Designers Edition it’s loosing engine coolant don’t know where or how but just keep refilling it & just recent it starts smoking like at least about 10-15 mins of running (White Smoke) … the longer it runs the more smoke ….. Do you have an ideal what’s causing this?

  39. I have a 1999 Honda Civic. It has 157k on it. I have driven in 2000 miles in the last year. It used oil, which I did not discover, until it was very low. Damn. Car was fine. Then a month later, I heard this awful metal noise under my hood, and temp gauge went up almost to the red mark. I stopped, let it cool, and drove it further, let it cool, etc. The noise stopped. The temp. gauge went back to normal. No problem. Two weeks ago, seems like it was leaking coolant.
    Engine started making marbles sound, with a squeaking, but this sound was not IN the engine.

    Two days ago, the heater stopped working, and I heard some marble sounds, and an awful metal loud noise. I was watching idle with the hood up, and the car just stopped. I went inside, and it started back up, and didn’t stall again. Yesterday, the car overheated again. Oil good. Exhaust good. Put coolant in the car, and it is leaking like sieve out of the left side of the car (when standing in front), close to where the radiator cap is. No matter how much I poured in, the more it just poured out. After I immediately poured it in, I started it, and took it down the street, engine sounded just fine, going slowly and accelerating. Temp. guage began climbing quickly, so parked it back in driveway. I think the radiator was empty, and when I filled it, the knocking stopped, and the engine was perfectly fine in operation. However, I filled the overflow last night, and it is empty tonight, before I drove the car.

    Do you know what this is?

    Thanks, Melanie
    I hope this isn’t a gasket. Sounds to me like a leak somewhere close to the radiator, but I cannot see where from underneath, because of a plastic shield meant to keep stuff from kicking up. It’d have to go on a rack. Hoses are not soft. Where the heck is this leak? It goes right through the radiator in a steady stream that is quick in flow.

    Any ideas?

    Now, the car has these marble sounds under the hood. So I stopped it immediately. A very little bit of steam was coming from the left side of the car when sitting in it. Tonight, I poured water into the radiator. It was flowing out under the car in a constant flow. So, I started up the car, it was making some noise, drove it slowly, and the engine started to sound fine. Working just as it should. I also poured anti-freeze in the overflow last night, and today it is empty.

    I have not driven the car since I parked it last night, until I put the coolant in to see if the engine would improve. It did. I am sure I have a leak in my radiator, or a hose, but I cannot tell what it is, because a plastic covering is obstructing my view. The lead is coming from the left side of the engine, but not from the engine (when looking at the car). I tried my hood up to see if fluid came out, none.

    What do you think this is? Fluids are the normal color, and no exhaust out tailpipe, except a slight amount three weeks ago.

    1. Melanie-

      Thank you for asking about your Honda Accord. Based on your description, it is a little difficult to diagnose exactly where the leak is coming from. Based on your description, it sounds like you may be losing fluid a little too quickly in order to get the benefit of using the BlueDevil Head Gasket Sealer. If you are losing fluid just as quickly as you add it, it doesn’t seem like you would be able to keep the product in the system long enough in order to complete the 50 minute idle. A hard part repair may be your best option.

      Thank you!

    1. Michael-

      Thank you for asking about your wife’s Chevrolet Traverse. Are you noticing a water/coolant loss? If not, you may have some debris or jellied antifreeze stuck in the system that is restricting flow and causing the vehicle to periodically overheat. If that is the case, we recommend flushing the system with the BlueDevil Radiator Flush http://store.gobdp.com/radiator-flush-00204/.

  44. I have a 2013 Dodge Journey 4 cylinder that is slowly losing coolant. The engine warms up to 3/4 on the Guage when sitting in traffic or idling but goes back to normal when driving. I have also noticed that when the coolant level is at full there are no problems. As it gets low I notice that the passenger side heat doesn’t warm up. Also, after driving I can smell some coolant when I am outside the car, never inside. I don’t see a leak anywhere and it takes about 2 to 3 weeks for the coolant to get to the low level line on the reseviour. Where cold it be going? Will one of your products help? How do I use it?

  45. I have a 2008 dodge avenger and out of no where my car thermometer went up to about 75% once I got off the freeway. I pulled over to the side and called my brother and told me to turn on my heater on full blast if I wanted to try and drive it home so I don’t leave it on the side of the road which I did and notice my heater wasn’t working and was shooting out cold air. When I parked my car at my place and turned my car off, my car let out a cloud of smoke coming from my hood. later on that night I went to check my oil and notice first that there was nothing in my coolant tank and second no oil in my car. I had a friend of mine check my car the next morning. Came to realize that no matter how much coolant we put into the coolant tank, it leaks out instantly like a waterfall. My friend was not able to detect where the leak is coming from. Do you have any idea what my problem could be and would your product help me at all?

    1. Krystal-

      Thank you for asking about your Dodge Avenger. If you are losing water/coolant just as quickly as you add it, unfortunately, the leak you have may be a little too extreme for the BlueDevil Head Gasket Sealer to be effective. A hard part repair may be your best option.

  50. I have a 2004 Dodge Durango V8 4.7L engine. I recently had the transmission rebuilt and they also replaced the thermostat. I have now noticed that I am losing coolant but have no leaks. Had to pull over on an emergency because it was hot and had no coolant in it. Let it cool down and added coolant and made it home. Since then we have been checking it and just can’t seem to find a pattern. Sometimes I can drive no problems other times I might go down the road and need to add coolant. Husband thinks a/c may have something to do with it since we drove about an hour with no a/c and coolant still full and on our way there we were using a/c and needed to add coolant. We are thinking of replacing the thermostat again since it did overheat that once but don’t believe that will make a difference. We live in Florida where the weather is always hot. Any recommendations would be appreciated. Thank you Carol

  51. Hi, I have a 2006 vw Passat. I car leaked out a full Reservoir overnight. After pouring in coolant to min. And turning the car on, I can see coolant dripping from the bottom. I think it’s the radiator but the way the car is designed, u can’t see the radiator. I want to know if I can use any of your products and if it’s safe to pour in the reservoir since you can’t get directly to the radiator.

    1. Jenny-

      Yes, the BlueDevil Radiator & Block Sealer (http://store.gobdp.com/radiator-block-sealer-00205/) would be able to seal the leak on your VW Passat. 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 overflow bottle. Once it has been added reconnect the hose and start the idle from that point.

      Thank you!

  52. I have a 2007 Toyota Rav4 2.2 Diesel SUV, it is loosing coolant with no visible leaks. I have to fill coolant so once every 2 weeks.
    The vehicle does not overheat and the radiator fan does come on very quickly.

    1. Tammy,

      Thanks for your question about your 2007 Toyota Rav4. It is possible that you have a blown head gasket and that is where the coolant is going, however, without any other indications it’s more likely that you have a coolant leak somewhere that is only leaking when your SUV is warm so the coolant comes out as steam and isn’t leaving any trace. You could try adding UV dye to your coolant and checking for leaks that way to see if you can find the source.

      Thanks again for your question!

  53. i just wanted to tell you (& others) how impressed and appreciative i am for this blog post! i am a woman who has always paid a mechanic to ‘just fix it’ and have never been interested in the details of what work is done to my vehicle, or even capable of understanding what my mechanic tried to explain. now out of nece$$ity, i need to pinpoint my problem. in order to do that i need to understand quite a bit more. this post is so well written that i am immediately able to comprehend what my cooling system does & why. the info-graphic is also very useful. you answer questions i didn’t know i need to ask and you explain why you’re telling me extra info. when i scrolled thru the first few comments, i saw post after post by women who sound like me: intelligent, interested, and probably not at all mechanically inclined. in fact i have never seen so many posts by women on any of the forums i have visited over the years (not trying to sound sexist). thank you so much for this post and for explaining what your products are and what they do and if they’ll work for my problems. (I’d previously been reprimanded for putting a 99cent sawdust product in my radiator & didnt understand why until i read that yours is non-granular & how it works). sorry for the long post but i felt i had to give you a HUGE THANK YOU!

  54. 2003 Chrysler Pacifica- Brandnew water pump & radiator installed & then 2 months later car overheated & confirmed blown head gasket from machanic. Used B.D. head gasket sealer product, flushed coolant, & replaced thermostat. Car has ran fine for 2 week around town & short distances only. Overheated today. Reservoir was empty. Added coolant, heat came back on & the car made it 20 miles back to the house without overheating. I don’t see any visible leaks, but I do still smell a sweet smell when the car is running. Wondering where my coolant is going if there are no visible leaks & if it possible that there is still a small leak at heads even after using Blue Devil. If so am I loosing the coolant through the exaust? Would a second Blue Devil Headgasket Sealer treatment be helpful? Thank you in advance for your input.

      Thank you for asking about your Chrysler Pacifica. How quickly are you losing water/coolant? Have you noticed any other symptoms, such as water/coolant getting into the oil or smoke/steam coming from the exhaust? 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.

      Thank you!

          Based on your description, it doesn’t sound like you have any of the tell-tale signs of a blown head gasket. Have you or a certified ASE mechanic verified where the leak is coming from? If not, they may be your next step. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

  56. I have a 97 Pontiac Bonneville with a 3.8L. The car was given to me about 5 years ago and ran like a champ, but one thing I noticed was whoever had the car before me put a PVC elbow on the one tensioner, crazy, but it held. I had the car down for about 8 months because I needed brake lines. Now that it’s back on the road I began having pressure problems but a new 16Lb cap solved that. I also put a new tstat in and it seems to run fine but when I turn it off it drains the reservoir and the rad is full. Cardboard under car shows no leaks. There is no white smoke, misfiring or any other problems, in fact, the car runs fine it just drains the reservoir. What could be causing this?

      Thank you for asking about your Pontiac Bonneville. Based on your description, it would be difficult to say exactly where the leak is coming from. It does not seem like you have any of the tell-tale signs of a blown head gasket or warped/cracked heads, except for the loss of water/coolant and pressure building up in the system. We recommend using a Block-dye test to test for combustion/exhaust gases being present in the cooling system. Doing so will give yourself a better idea of what the issue is. If the results don’t show any carbon gases being present, you may want to bring the vehicle in to a certified ASE mechanic for a proper diagnosis.

      Thank you!

  57. I have an 03 Chevy Malibu, the antifreeze in it will run low, but never completely gone…We go thru about 2 gallons of it a week. The cars runs fine and had no issues other then going thru antifreeze fast and on occasion it runs a little warm but once we start moving the temperature goes back down. What could be the problem?

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.
