Having your car overheating can be a frustrating thing. For the most part your car’s cooling system probably works pretty well and you don’t give it a second thought. When it overheats, it can leave you quickly stranded and stuck not only with a tow truck bill, but a steep repair bill as well.
Vehicle’s cooling systems today have gotten a lot more advanced than they used to be. The basic principle is the same but the radiators are made with more advanced designs, the fans are much more efficient and the thermostats are less prone to failures. Many car manufacturers today are so confident in their vehicle’s cooling system that they don’t even include a coolant temperature gauge on your dashboard anymore.
Keeping a close eye on your coolant temperature gauge or warning light is one of the best ways to prevent your vehicle from overheating. Once the gauge rises above normal, or the warning light comes on, pull over immediately and turn of your engine. This will stop the input of heat and get your vehicle to start cooling down. Unfortunately, this is just a short term solution but it will keep any further damage from happening to your car. If components in your engine are allowed to get too hot it can cause major permanent damage like warping, cracking, blown gaskets, ruptured hoses or broken thermostats.
If you find your car overheating and you’re close to home you can drive it for short distances and turn it off once the temperature gauge rises allowing it to cool again. This may help you save money on a tow truck but remember to not let your engine get too hot!
Why Is My Car Overheating?
There are quite a few reasons why your car may be overheating. The main goal of your car’s cooling system is to remove heat from your engine block by running coolant through cooling passages and transfer that heat to the air through the radiator at the front of your car. Your water pump is driven by a belt connected to your crankshaft and is the motive force for moving the coolant around the system. If your car is overheating it can either be because the coolant is not moving fast enough, the heat isn’t getting transferred out of the engine to the coolant, or it is not getting transferred out of the coolant to the air through the radiator.
To find out which of these problems you are having, you can take temperature measurements around your vehicle. The best way to do this is using a non-contact thermometer. Non-contact thermometers use the infrared radiation emitted by a warm object to determine its temperature. Measuring the temperature at the inlet and outlet of your radiator, thermostat, and water pump can help you determine if your system is clogged or fouled and what the likely culprit is. If you don’t see a large, uniform temperature drop from the inlet to the outlet of the radiator, you may have a clogged radiator. If you see a large temperature drop across your thermostat or water pump you may have a broken thermostat or a broken water pump. If you don’t see a large temperature rise from the water pump outlet to radiator inlet you may have scaling in your engine block and be in need a system flush.
Before you complete any of these diagnostics you need to make sure your cooling system is filled properly to make sure you get accurate readings. Most vehicle’s cooling systems have an overflow tank or expansion reservoir. As your cooling system heats up, the coolant will expand. As the coolant expands the pressure will rise in the system until it reaches the pressure of the radiator cap. At his pressure, the radiator cap will allow coolant to escape to maintain a constant pressure in the system. This escaping coolant is captured in the coolant reservoir. When you park your car and turn it off, the coolant will cool and contract. The radiator cap will then allow the coolant in the coolant reservoir to be drawn back into the system making sure air bubbles do not form as things cool down.
If your cooling system is not completely full of coolant at all times, it will not operate as efficiently as possible and may be the source of your overheating. You can check to make sure your system is full by checking the coolant reservoir. If it has coolant in it when your car is completely cold, like after sitting all night, then your cooling system should be full and free of air. If you check the reservoir and find it empty, it is an indication that you have a low coolant level, even if it has some coolant in it when your car is warm.
If you find an empty coolant reservoir it is an indication that you have a leak in your cooling system. If this is the case, add BlueDevil Radiator and Block Sealer before you top off your cooling system with new coolant. BlueDevil Radiator and Block Sealer is a special formulated liquid sealing agent that you can add straight to your radiator. BlueDevil Radiator and Block Sealer will not harm your thermostat or water pump, but it will seal a leak in your system whether it is in the radiator or block and in steel, iron, aluminum or plastic.

I have used bluedevil in my car for overheating and even though originally it didn’t help. After about a week it seems to be kicking in. However, when I turn on the hot air in the car that doesn’t work. Cold air is still coming out. Any suggestions?
David-
The first thing I would check is that the thermostat is installed and functioning properly; you may have to replace it or install a new thermostat if it is not currently in the system. The other possibility is that there is an air bubble stuck in the system and it needs to be bled out. You may check your owners manual on how to properly bleed your system.
Thank You!

I have a 1998 Cadillac Seville that keeps over heating. Just replaced the thermostat and got a new oil change..that seems to not help water seems to not circulate right in the radiator. Water don’t move at all and the hose keeps getting real tight n car running hot every mile and antifreeze leaking from bottom of car.
Cartavian-
Thank you for asking about your Cadillac Seville. Based on your description, we recommend using the BlueDevil Head Gasket Sealer, found here on our website: http://store.gobdp.com/head-gasket-sealer-38386/ . The directions will have you remove your thermostat and perform a cooling system flush prior to using the product, which will improve the circulation in the system and help it from overheating during the 50 minute idle.
Thank you!

If your water isn’t flowing, consider replacing your water pump. It probably has a lot of scale buildup, and the internally sealed bearings will wind and strip, causing the pump to not operate. Thermostat operates based on temperature and pressure to open.
Is it the upper radiator hose that gets full or hard, or is it the lower hose?
I have a honda odyssey 2005 and is overheading and i got my instake hose broken that can cause to the overheading?
Joel-
Yes, a loose or disconnected cooling hose could definitely cause the engine to overheat. We recommend replacing the hose and potentially replacing the hose clamp.
Thank you!

Hello, my name is Tonya. I have an 02 pontiac montana that was overheating, and blowing cold air out of the vents. I replaced the water pump and thermostat. I have coolant in my radiator and the overflow tank and it’s not leaking. My serpentine belt was also changed but that has nothing to do with the issue. What could still be causing the engine to overheat after replacing the water pump and thermostat? We also bled the radiator to make sure there wasn’t any air bubbles. Please help.. Forgot to mention that we checked the oil also and it doesn’t appear to have anything mixing in it.
Tonya-
Thank you for asking about your Pontiac Montana. It is also 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 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!

Your thermostat is not working thank you
Hey I have a 2004 dodge strauss. I’ve had the replaced all of these:radiator, refill jug, and water pump and water is still running out from somewhere. My son checked to make sure the water and oil wasnt mixing. Can u tell me what could it be causing this.
Lakisha,
Thanks for your question about your Dodge Stratus. Based on the components you replaced, the leak could still be coming from one of your radiator hoses, the thermostat housing, your heater core or your head gasket. In order to choose the correct leak stop agent, or replaced the problem component you need to identify where the leak is coming from. You can try putting UV dye in your coolant and checking for the leak using a black light or cleaning your engine bay very well and then letting your car idle until you discover the source of the leak.
When you find the leak, you can use the appropriate BlueDevil stop leak product to seal your leak and get things back to normal.
Thanks again for your question!

Hot air instead of cold air…
Are you talking about your air conditioner/heater? If so, check for plugged heater core, stuck thermostat, or air in cooling system.
Will it help the over heating for how long

I have an over heating problem on my 94 Mercedes benz SL500, I did put a new water pump, changed all the hoses, installed a new thermostat, installed a new fan clutch, took the radiator out and took to a radiator shop, there is no leaks, or clogged places. the temperature almost reaches the max. 120 degrees, I turn on the hot air in the blower to bring the temperature down. at idle I removed the cap of the radiator reservoir, the water comes out like a fountain when it reaches the 120 Degrees, and when I put the cap back on, the upper radiator hose becomes very hot and very stiff, and does not look like the water is circulating to the engine. did the chemical test for the radiator water tank and it did pass without any yellow color, I am trying to do a compression test on all the cylinder but it seems they are functioning properly. no white smoke coming out from the exhaust, I also, did put a sea salt in the vacuum lines system, it did smoke for a little bit but not much and stopped smoking. I don’t know if your product is going to fix this overheating problem or not?????
George,
Thanks for your question about your Mercedes SL500. It sounds like you’ve done just about everything to fix any overheating problem besides a blown head gasket. The reason your hoses are getting stiff once you put the radiator cap on is that the system pressurizes to the pressure of your radiator cap spring as it heats up so that doesn’t necessarily indicated a clog in your system. Some auto parts stores sell a chemical test you can do on your engine coolant to check for the presence of exhaust gases. If you can find one of these tests, it will be able to tell you if you have exhaust gases in your coolant indicating a blown head gasket. If you can prove that, then BlueDevil Head Gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/) is guaranteed to seal your head gasket leak.
i have ford escape 2001, same problem. overheats so i replace thermostat because it stucked, then new thermostat is there but still overheats after 15 mins drive. i open the reservoir tank and water is like fountain, i keep bakc the cap but not fully close, now it will not overheat, but i now i can see water spray on the reservoir hose and hissi.g sound due to release of heat ib the hose. can this be blown head gasket? and can i use blue devil.? jm in bahrain..

i have a 2000 Honda civic ex the previous owner overheated the car and didn’t know it was overheating and kept driving it till it shut down. when i got the car it wasn’t having problems but when i drive my car and in traffic it overheats slowly but when i move it goes down. the fan does not spin when idling. idk if i have a short or my fan motor is messed up someone help me please.
Shaun,
Thanks for your question about your Honda Civic. Your engine cooling fans shouldn’t spin at idle unless your car is warmed up, and even then they should cycle on and off. If your car is overheating, even slightly, and the fans aren’t on then it does sound like you’ve got an electrical problem. Start by checking the fuses and relays for the fan. Ther other possibility is that some wiring was damaged when the car overheated so check for melted or frayed connections. Lastly, it is possible that the high temperatures ruined the temperature sender that signals the fans to turn on so you may consider testing or replacing that sensor as well.
Thanks for your question!
-BD Auto Pro
I have a vehicle that is doing something similar. It will reach high temperatures while idling or at a stoplight/sign–however I can drive on the highway all day long or even if I just keep moving in town, then it doesn’t reach high temps. It hasn’t technically overheated YET, but I would like to fix the issue before it reaches that point.
It has coolant in it, has a new serpentine belt, and running the heater has little to no effect on the temperature. If it is sitting at an idle and I rev it, the temp doesn’t necessarily skyrocket nor does it drop drastically either (it pretty much stays the same).
Fan issue?? Thermostat?? Water pump?? I’m lost..
Keela-
Have you noticed whether the fans are coming on or not? Is the vehicle losing water/coolant or is it reading at the normal level?

My name is lashawn and I put new things in my car thermostat, upper water hose, radiator, tempature sensor, gasket , o- ring . My car still gets hot quick. Cause the housing get hot and when I go around the corner that’s when the gauge shoot up to the h line quick. Do I change the water pump,heater core,or a fuse?
Lashawn,
Thanks for your question about your car overheating. If your car is heating up that fast, it sounds like your water pump may be malfunctioning so we would recommend starting there. If your heater core is clogged, it could cause the same problems. If that is the case, you would have cold air blowing out of your vents even with your heat on full and your car over heating. If this is the case, use BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/) to clear the blockage and increase the efficiency of your cooling system.
Thanks again for your question!

I have a 2006 dodge stratus. My problem is my overflow is boiling and the car is overheating. But at the same time, my car didn’t tell me it was overheating. I recently had my alternator and tensioner pulley replaced. Just curious as to what it could be
Tasha-
It is possible that you have a defective thermostat. As for the boiling in your coolant reservoir you could have a “Block Dye Test” done on the vehicle to determine whether or not combustion/exhaust gases are present within the cooling system. If they are present then we recommend using the BlueDevil Head Gasket Sealer to remedy the problem.
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 a low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will sometimes 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.
**Note: Based on your cooling capacity you will only need to add 16 ounces of BlueDevil.

my 1994 Honda civic had a blown head gasket so i had the engine replaced with a manufactured engine . and it was working good yesterday my daughter was driving the car and all of the sudden the car got hot and a lot of water came out of car she turned off the car and when it goy cold we added more water and drove home when we got home the water came out again and car got really hot. I checked the hoses and took the radiador out and put water on it to see if it leaked and it did not could you advise
Gilbert-
Thank you for asking about your Honda Civic. Based on your description, unfortunately, we would not recommend using the BlueDevil Head Gasket Sealer in this situation. It seems you are losing water/coolant a little too quickly and would not be able to keep the product in the system long enough to complete the 50 minute idle. We recommend taking the vehicle to a certified ASE mechanic for a proper diagnosis and possible a hard part repair.
Thank you!

Hi, I have a 2004 KIA sorento w/127,413 miles. Last week while I was driving I noticed while I was at a red light the temp gauge was climbing, when green light came on and I started moving the guage went back down. So at every red light the temp climbed twice maxing out, I turned on my heaterfull blast to help, every time I moved again it would go down. After got home let car cool down and opened overfill tank for radiator and saw it was bone dry. Filled it up with 50/50 antifreeze/water. Drove it next day and temp stayed normal however I could smell antifreeze and after car warmed up I noticed a little smoke/steam either one or the other. Its been 2 days since I filled up resovouir tank and even today while I didn’t see smoke/steam I smelled antifreeze loudly after I got out of my car. Also to mention after I drove it(62 miles) day after filling up overfill tank, I had to add about a 1/4 gallon of water to overfill tank because I didn’t have antifreeze on hand. I haven’t checked it today yet but am anxious to to see if and how low it is. Any suggestions will be appreciated.
Tina,
Based on all the indications you’re seeing it sounds like you’ve got a coolant leak somewhere. That would cause your car to overheat at stop lights and the steam you’re seeing. If you can locate the leak, it would allow us to better recommend one of our leak stop products. If you simply have a cracked or broken hose you can replace that easily, otherwise we would recommend using BlueDevil Pour-N-Go and BlueDevil Radiator and Block Sealer depending where the leak is from.
Thanks again for your question!

I have an 02 Chrysler Sebring 2.7 liter. It has an intermittent heating problem. I changed the thermostat the radiator cap, water pump. I bled all the air out of the system. It doesn’t seem like it’s losing liquid. After I change the thermostat it went away so I thought that was the problem then came back recently. Don’t notice any signs of a blown head gasket. Didn’t check 4 exhaust fluid in the coolant with the test. I know that my hi fan doesn’t kick on but I have driven it on hot days in hundred degree weather with only the low fan and it doesn’t overheat. my mechanic cannot figure it out. Any ideas thank you.
Sharif,
Thanks for your question about your Chrysler Sebring. The only other thing we can think of is that your cooling system may need a flush. If the new thermostat and water pump fixed the problem for a little while, the increased flow of new components could have hidden the problem for a little longer. Try using BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/) to clean our your radiator, engine block and heater core to make sure you’re getting maximum heat transfer and see if that helps keep your car cool.

I have an Audi A4, I noticed it was overheating after driving a short distance and on checking the radiator the coolant has completely dried up, waited for a while and add water. After a short distance the temperature gauge was already blinking and when I checked the water has dried up, there was no leakage whatsoever. What could be the problem and what can I do.
Wendy-
The water/antifreeze really wouldn’t be able to “dry up” in that short of a distance. It sounds like you definitely do have a coolant leak even though you are not physically seeing the fluid come out.
Due to the extent of the problem please contact us at 888-863-0426 so that we can get a clear idea of just how quickly the water/antifreeze is being lost. This will help us be better able to make the best recommendation.

Hi , I have a 2002 pt cruiser that’s been overheating . I replaced thermostat . Replaced radiator cap . Bled system. It still seems to overheat. Temp gauge is at half way mark . It’s not showing that it’s overheating but then I stop and its steaming and I could smell coolant really strong . The resorvoir has coolant but radiator needs water. It been getting hot at stop and goes . There is no water leaking. At times it sounds like it boiling. But not sure. Like I said the temp gauge is at halfway mark.

Hello, I have a 1993 Toyota Paseo with an overheating problem. Before leaving for work every morning, I check that there is water in the radiator and coolant resorvoir. However, for the past couple of days, my car has been overheating when I am half way to work. I pull over before the needle reaches the red markings on the temperature gauge. When I open the hood to check the engine, there is white smoke coming out from the hose in the coolant reservoir while the tank is empty and water is sprayed everywhere under the hood. After the engine cools down enough, I open the radiator and see that it is completely empty as well. Is it possible that I may have a leak somewhere or is it something else?
Alex,
Thanks for your question about your Paseo. To be honest, it sounds a lot like you’ve got a blown head gasket. If you simply had a leak, you would see more liquid coolant rather than steam and water sprayed everywhere. Try simply allowing your car to idle in your driveway as it warms up with the hood open and check for liquid leaks at all of your coolant hoses to see if one of them could be the culprit. You can also try having a pressure test done on your cooling system to help find the leak, or checking your cylinder compression to see if there is low compression on one or more cylinders which would indicate a head gasket leak.
Thanks again for your question!

I have Audi A4 2000 model 2.4 litre. It started overheating and took it to mechanic. After fixing the now whenever I stop water drop from coolant bottle on breather hole. I even notice that there is oil in my coolant.
Astimas-
Unfortunately, the BlueDevil Head Gasket Sealer is not designed to stop oil from entering the cooling system. It is specifically made to stop coolant loss; it would work for water/coolant leaking into the oil but not the other way around.
We do not manufacture any products that are designed for stopping oil from entering the cooling system.
At this point you may need to take the Audi to a certified mechanic.

I have a 1998 Chrysler concord and it has been overheating the past few days. got an oil change yesterday and the mechanics said that everything looks fine that they could look at from it. every now and then my car also makes a weird loud noise when I accelerate but lately it will overheat if I drive it for 10 minutes. anyone know what this might be?
Brianna-
Thank you for asking about your Chrysler Concord. Unfortunately, your vehicle can overheat for a number of different reasons. Whether it be a loss of water/coolant, jellied antifreeze in the cooling system restricting or clogging flow, a defective fan switch or fan clutch or even a faulty thermostat. Have you noticed any water/coolant leaks? If you are hearing the fans kick on after the vehicle gets up to temperature, a good place to start would be checking the thermostat. You can check to see if the thermostat is working properly, by placing it in boiling water and make sure it is opening and closing at the correct temperatures. A cooling system flush might also help, especially in higher mileage vehicles that this service hasn’t been performed on, as this is part of the vehicle’s routine maintenance.
Hope this helps!

I have a 2002 Honda civic ex with the D17a2 motor, I have to fill my radiator with water every single morning due to a slight loss but no shop or garage can find the leak they’ve done pressure tests, block tests and nothing has shown anything so recently one shop did a block test and it took 30 minutes to change the fluids color… They said I have a slight head gasket leak and there is water underneath my car but I also run with the heat barely on so could that be condensation? It only overheats when the coolant gets too low but I don’t let it go that low, I refill every chance I get. Any ideas where to check? I’m completely confused since when off I can’t seem to locate any leaks, no white smoke, no smoke off engine, lost…

We recommend using BlueDevil Head Gasket Sealer for your Honda.
Based on the block test 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.

so I have a 08 chevy Malibu, my thermostat was changed twice, some sort of hose was changed, I was told by the mechanic that if the gage starts going up then to pull along side the road and open the cap where you put antifreeze and let the air out.. well I did was I was supposed to but now from the front of my car it leaks to almost pours out antifreeze, we go through that stuff like crazy. now the fans take about 3-4 mins for them to shut off once you shut the car off.
can you help?
Jori-
Depending on how quickly you are losing antifreeze, you could potentially use BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). In general, as long as the vehicle will run for a 50 minute idle without losing more than about 1 quart of water/coolant and it will not stall out or overheat then there is a very good chance that BlueDevil Head Gasket Sealer would work to seal the leak for you and stop future coolant loss. You will only need 16 ounces of BlueDevil to properly treat your Malibu.
Feel free to contact us at 888-863-0426 with any questions.
Thank you!
-BDP
Just to make sure, did you re tighten the cap after you let the air out? What the mechanic was probably having you do is to vent any air bubbles that build up and re-equalize the pressure. Also, if there was a lot of pressure build up and it’s an older cap, you may want to consider replacing the cap itself. This is generally a cheap part, and is amazing how often it’s the cause of overheating.
I have a 2004 Pontiac Montana and it keeps over heating I let all the antifreeze out put water n i even put water in through the hose to flush it…..that worked all nite and a day later its doing the same thing over heating

I have a 2000 Chevy Malibu. It was running hot, so we replaced the thermostat. After that the heater only blows cold air and it is still working hot. We bled the system. What else could this be?
Danielle-
It sounds like you may have a head gasket or block leak where combustion/exhaust gases are pushing into your cooling system and eventually causing the engine to overheat. Please contact our tech support team at 888-863-0426 so that we can discuss your vehicle and potentially give you our recommendation.
We are available Monday – Friday, 8:00 AM – 5:00 PM Eastern Standard Time.

I have a 1996 Cadillac Seville with the Northstar V8 Engine. Bought the car at an auction. Just driving it home about 2 miles on the road noticed vapor smoke escaping from the passenger side hood area. Then followed by overheating. Pulled over & after a short cooling off inspected the Radiator cap, it was old and bad. Added water & Replaced cap with new one. This got us all the way home however temperature rising and falling. My mechanic had it for two days. He bypassed the heater core…no resolution. Then he removed the thermostat…no resolution. He tells me its gonna be the head gasket & that is starting to go bad however there is no smoke. HG repair will cost $2,000. I had to pass.
On the way home, the connected the heater core bypass gave out and released the pressure essentially braking the connection. If I were to reconnect the hoses with a universal plastic connector and tighten them with vent gear clamps then use your product do you think it would work. Thank you.
Oscar,
Thanks for your question about your Cadillac. Blown head gaskets have been know to happen on the Northstar engines so your mechanic may be correct. You can reconnect the hoses used to bypass your heater core, but make sure you use a suitable connector that can handle the chemicals in your coolant and the pressure of your cooling system. Something like a schedule 80 PVC nipple should work temporarily, but be sure to ask the sales associate at the store. Once you’ve got a sealed system, we recommend using BlueDevil Head Gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/).
Thanks again for your question!

i have a 2000 pontiac sunfire and after a few minutes of it being started it starts to over heat i think it might be the thermostat and we changed it but it still says after a few minutes of it running that its over heating could it be something wrong with with the sensor or the circulation
William,
Thanks for your question about your Pontiac Sunfire. You can use a non-contact thermometer to measure the temperature of the top of your radiator to see if your car is really overheating or if the gauge is malfunctioning. Your thermostat should open at 180 degrees and the temperature gauge shouldn’t read high until the temperature gets over 200 degrees.
If your car is overheating that fast we would recommend checking to see if there could be another cause besides your thermostat like a low coolant level, failed electric fans or a clog in the system. If you haven’t done it recently you can try flushing your system using BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/) and adding new coolant to see if that helps cool your car down.
Thanks again for your question!

I have a 2005 Audi A4 s line. The water coolant reservoir spurts out furiously through the water reservoir cap after driving for about ten minutes. I checked to ensure no air in the. System and replaced the cap but this has not provided a solution.
Paul-
Thank you for asking about your Audi A4. I believe you may be referring to the combustion leaking into the cooling system.
If the vehicle is in fact getting combustion/exhaust gases blowing into the cooling system and creating pressure then we recommend using BlueDevil Head Gasket Sealer. 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.
Feel free to contact us with any additional questions.
Thank you!

Hi,
My name is Gigi I have a 2004 Oldsmobile alero. This summer has been the worst it always overheating and I can never go far. I replace the thermostat twice and the pump but still overheats. I hire a private independent car repair man he had clean the filters because it was dirty and for one day the car was able to travel far distance. The next day it over heated and I always have to add coolant or water into the thing so I can get home. I’m not sure what’s the problem maybe the water pump or the two fans or the whole car computer. I’m not sure if this car is worth saying anymore
Gigi,
Thanks for your question about your Oldsmobile Alero. If you’ve replaced your thermostat and water pump already and are regularly adding coolant then it sounds like you’ve got a leak somewhere. That leak could be allowing coolant to leak out which would cause the overheating you’re describing. The leak could be anything from a leaking radiator, a bad cooling hose, or any other number of things. Once you’ve tracked down the leak, you can replace the leaking component or try using the appropriate BlueDevil stop leak agent to seal the leak and keep your car from overheating.
Thanks again for your question!

My car just started to overheat yesterday I was on the highway the indicator light came on and I pulled over. I open the hood and the reserve tank was empty. So then I pour antifreeze in and it pours out from underneath the car like a fountain. What’s wrong with me car it’s a 2000 Chevy cavalier
Hyam-
It sounds like you are losing a extreme amount of coolant. This could be attributed to a blown/leaking head gasket, leaking intake manifold gasket, or a cracked block.
You may want to have a certified mechanic take a look at your Chevy for proper diagnosis. Once it has been diagnosed you will have a much better idea on what your options may be.
Thank you!

Hi i have a honda accord 2000 and my car overheated today, we found out thst it didnt have any antifreeze in it. So we just added it. How long does it take for the antifreeze to make the temperature go back done. Should i buy more antifreeze just in case? I dont have anyone to help me to find out what can make it better.

I have a 2000 Honda civic, for about a month now my temperature gauge has been fluctuating to the red mark and down sometimes when I drive. Other times it stays up high when I drive. I tried bleeding the system and it works for only 3 days at a time and then it starts acting up again. The fans work and the water pump is fine. It only fluctuates after I drive it for a while. If it sits and idles after hours of being off it won’t budge pass half way. When I bled the system I saw bubbles and just the other day while driving my temp gauge sky rocketed. I pulled over and found out my radiator was bone dry. There is no smoke from the exhaust, no milky color in the oil and no noticeable leaks coming from the car. I need help

Hi! I have a 2000 dodge caravan I drive to & from work everyday. Around the same time every morning, the temperature gauge shoots up to hot, stays hot for the same length of time, then goes back down to normal. And usually turning the air conditioner on (although I don’t have air conditioning at all in my car) helps it go down faster. Antifreeze only lasts in my car for about a week but even with it in, it still shows it overheats on the gauge. I never smell antifreeze and it never steams up. Can you help?
Kayla,
Thanks for your question about your Dodge Caravan. Our first recommendation would be to replace your thermostat. It sounds like it may be sticking shut until your car gets to a high enough temperature then it pops open and allows everything to work properly. You may be loosing antifreeze when your thermostat opens if things really are that hot then a small amount of it would probably flow out of the overflow hose. When you get that replaced you may consider having a cooling system flush performed as well to make sure everything is working properly.
Thanks again for your question!

I have a 2007 Dodge Charger SE 2.7L, the gauge goes to red and heats up after 10minutes on the freeway, but does not while idling. Only after it runs hot the coolant inside the reservoir is hot and some escapes the reservior to relieve pressure it seems. Could it be a clogged heater core hose, water pump…? dont see a leak anywhere, Thanks!

Our 97 Toyota Avalon ran hot about 2 months ago for the 1st time. We replaced the Radiator & Hoses . But, it is still getting hot. Sometimes you can drive it for 30 minutes and the Temperature Needle doesn’t get any hotter than the halfway mark. Sometimes it will get hotter than the halfway mark after driving it for 20 mins. We just replaced the Thermostat (9/21) on today. When we put Antifreeze in the Radiator a lot ran out. We let it idle for about 20 mins in the driveway & the Temperature Needle got a little higher than halfway. Any Reccommendations?
Barbara,
Thanks for your question about your 1997 Toyota Avalon. The only part of your cooling system you haven’t replaced is the water pump, so it is possible that your water pump is failing and not circulating coolant properly. You may also consider performing a cooling system flush using BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/). Since your car is almost 20 years old it is possible that corrosion products have built up inside your cooling system reducing its efficiency.
Thanks again for your question!

My 2001 honda civic has been overheating for almost 2 months the fan appearedtobe tied down preventing the fan from turning on thought it was the plugs that the fan some how had a bad plug or a blown fuse none was the issue bought used fan to fix the issue of the fan not turning onwhen its supposed to fan was not the issue car still overheats but not everytime i drive it. Normaly when i drive for 30 to 40 min it then overheats quickly. Im missing an overflow cap and it dont seem to be leaking anywhere so i replaced the thermostat it seemed like it was sticking shut and wouldnt open put new one on and it overheated the first time i drove it overheated before the water sounds like its boiling sometimes when i stop to cool it down one night a largamount of whitesmoke was coming out of the radiator after i removed the cap im not sure the water is actualy circulating through the car. Everone says its a blown head or warpedhead but there is no white smoke coming from exhaust or anything in the oil the car does last longer when i put antifreeze in it but i thought antifreeze was needed only when trying to heat the car up so i shouldnt need antifreeze since i have no need to heat the car. It normally takes 30 to 40 min to overheat thenit cools fairly quickly like 15 to 20 min the tempature gadge seems to be barley a smige over the cool mark its not even reading half way hot so i fill the radiator and overflow and ican drive sometimes 30 to 40 min then its overheating again. Please help me understand before i go insane.

I have a Toyota 1996 Camry Le my car once over heated so I got it looked at. Was told it was a water pump bc of a small leak so I change the water pump and thermostat along with radiator cap well it didn’t fix the problem my car was idle a little and acceleration wasn’t good so thought it might be a head gasket so I got it looked at again come to up with the problem had 2 bad spark plug wires so I got them changed and car now runs good bt now when I drive like 35 to 40 miles my temp gauge kinda goes up close to the red mark bt not quite when I try to pull over and stop by the store so I pull out the store bc was scared it wud shut off and drive off and soon as I drive off temp gauge goes back down to half way mark or when I turn my heater on bt soon as I get to the house and almost stop to turn off car it kinda goes back up again so I just shut it off and pop my hood to check and my car seem to be not over heated bc there’s no smoke or anything it’s like it’s kinda normal just need some advice on what this might be? bc now im always constantly looking at the temp gauge when driving bt always nervous too plz help if u can?

Kareema-
Thank you for asking about your Dodge Intrepid. Some other possibilities as to why your vehicle is overheating could be poor circulation of your water/coolant. This may be due to a restriction in the cooling system, in which case we would recommend having the cooling system flushed. It may also be due to a faulty water pump. We recommend taking your vehicle to a certified ASE mechanic for a proper diagnosis.

Hi. I have a 2002 Cadillac Deville. It overheated yesterday, checked coolant and was empty (weird because I had checked fluids 3 days prior and coolant was full). Added coolant til full again, today drove car and after about 10 miles, overheated again. Checked coolant, and empty again. I know it has the crap North Star motor, and I’ve heard how common it is for head gaskets to go. I noticed the fans under hood aren’t turning on. Help…

Thank you for asking about your Cadillac Deville. In order to get the benefit of using the BlueDevil Head Gasket Sealer http://store.gobdp.com/head-gasket-sealer-38386/, the vehicle would need to be able to maintain idle for a full 50 minutes and you shouldn’t be losing more than about a quart of water/coolant during that 50 minutes. Based on your description, unfortunately, it sound like you are losing coolant a little too quickly for the product to be successful. A hard part repair may be your best option.

Hi,I have a 1999 Monte Carlo,It’s been overheating after being driven for about 10-15 minutes.Even though it’s being driven on the highway with very little traffic it’s still going to hot pretty fast..The radiator was flushed,the water pump was replaced,thermostat was taken out,and antifreeze was added to radiator but still keeps overheating.When the heater is turned on only the drivers side gets hot and let’s out very little heat even though it’s on full blast, while the passenger side stays blowing very little cool air.For the past couple of days I’ve also noticed white smoke coming out from the exhaust pipe. There are no water leaks anywhere that can be noticed.Is there something that should have been done that hasn’t been done yet? Please help me if you can.

I just used the head gasket sealer about 5 hours ago, had the 2001 volvo s60 in idle for an hour with bd in the engine after flush but i want to know should I idle the car again for another hour and let it sit in overnight? Also id like to know if i can drive the car in the morning to work (5 miles away) with my thermostat still removed, and change coolant and thermostat when i get back home?
Thomas-
The BlueDevil Head Gasket Sealer only reacts to heat once (one heat cycle). After you complete the 50 minute idle and shut the vehicle off, any extra BlueDevil in the system would be like extra water. It will not continue to react or continue to seal. Yes, it would be safe to drive the vehicle with the thermostat still removed. Feel free to contact our technical support line at 888-863-0426 with any other questions.

Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

I have a 2005 Pontiac got and it started with my car overheating and I went to get a pressure check based off of some coolant that was by the side of the radiator….got it tested and there was a crack at the radiator …I installed a new radiator and didn’t solve the overheating then changed out the water pump , thermostat and engine coolant temp sensor and still overheating…I did the combustion leak test to see if gases were in the cooling system and the dye stayed blue…so what could be the issue? A clog? Needs to be fully flushed…? Also I’m not getting any heat when the heat is turned up on high…please help so I can ride my gto again

Thank you for asking about your Pontiac GTO. It is possible that when the car initially overheated, that it blew the head gasket. Are you still noticing a loss of water/coolant? If not, we recommend flushing the system with BlueDevil Radiator Flush http://store.gobdp.com/radiator-flush-00204/. The Radiator Flush would be able to get rid of any kind of restriction in the heater core, as well as the cooling system it self.

Hi sir , im muhammad idrees, i have dodge charger 2.7L 2007, i have issue of overheating , i took it to machanic and he changed water body plus timing belt adjuster and also cleaned the rediator, but the issue is that after driving 20-25km the car got overheated like water start boiling and the gage going up, some times it overheated so quickly and sone time take time, it has no issue of starting or anything so some machanics are saying to change the engine, that i really dont want to do, so kindly if u guide me something ??
Muhammad-
Thank you for asking about your Dodge Charger. 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 so, we recommend using the BlueDevil Head Gasket Sealer http://store.gobdp.com/head-gasket-sealer-38386/.
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.

My car over heated the plastic container that you add water or coolant to was full , and radiator was empty when we pulled over and checked , also the lid to the plastic container that you add water or coolant to is broken a little bit ? Can the cap be the cause of the car over heating or could I need a flush ? We had new front motor mounts added when they lifted the engine to replace motor mounts could something been disconnected ?

Thank you for asking about your Chrysler Cirrus. Based on your description, we recommend taking the vehicle in to a certified ASE mechanic for a proper diagnosis. The overheating your car is experiencing could be from a number of different reasons. Has the water pump been replaced? Is the thermostat functioning properly? It’s possible the coolant isn’t circulating properly because of a faulty water pump or thermostat. A proper diagnosis would get you in the right direction. Feel free to contact our technical support line at 888-863-0426 with any questions.

I have a 96 Buick century and it’s running hot and leaking coolant and none of the hoses or jugs have cracks or holes I wanted to know what do I need for this problem.
Monique-
Thank you for asking about your Buick Century. Based on your description, we recommend using the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). As long as the vehicle will maintain idle for a full 50 minutes, and you are not losing more than about a quart of water/coolant in that 50 minutes, you would be a great candidate for the product.

Thank you for asking about your Honda Civic. Based on your description, it is tough to say why the vehicle is overheating in this case. If you haven’t done so already, we recommend flushing the cooling system with BlueDevil Radiator Flush (http://store.gobdp.com/radiator-flush-00204/).
Another possibility, depending on the mileage, cold be a faulty water pump. You may want to bring the vehicle in to a certified ASE mechanic for a proper diagnosis.

My car doesn’t have any leaks that are visibly.I need some help to figure out what is wrong. This is the only car i have to get atound in with my 2 younger children.
Connie-
Thank you for asking about your Honda Accord. Is the vehicle overheating at all? Are you seeing any smoke coming from the exhaust? Are you noticing any other symptoms, such as rough idle or a bubbling or boiling over in the cooling system? 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.

I have a 2004 Chrylser Sebring Convertible Limited. I’ve had it for 3 years, and there have been issues, but this time, it overheated. I check my fluids and my coolant was about 1/4 low. It was enough to get to the auto store to get more, as it is the red coolant and I only have green. It wound up overheating. I had to add water as the first time it was not in a good place. The second time, I still didn’t make it to the auto store, but a safer place to be towed. Is it possible that coolant just needs to be added and it would be okay or could it be a larger issue? I am on Social Security Disability and don’t have the money to both fix this car nor get another one. So I am truly at a loss right now. Any help you can give me would be very much appreciated!
Thank you,

I have a 2002 Lincoln ls v-8 the car started overheating after my wife one day turned on the ac which continued to blow out hot air sunce then the car overheats it will hit the halfway mark (on.the dash) within 7 mins of driving it and give or take another 7 mins before the theromostat light comes on. After the needle hits midway you can hear the fan kick on but its loud and sounds like its struggling. I was wondering would it be the theromostat, water pump or fan or fan belt
Tre-
Thank you for asking about your Lincoln LS. Based on your description, it could be either the thermostat, water pump or fan belt/ fan clutch. The thermostat would be the best place to start, as it would be the easiest and cheapest to replace. It is typically recommended to have the water pump replaced every 90,000 miles, so depending on how many miles are on the vehicle, it may be time for a replacement.
Thank you!

I have a 98 Ford explorer awd. It seems like the truck is getting super hot but the temperature gauge doesn’t rise above normal/middle. I checked under the hood and the big hose from the radiator is hot and tight as hell. The truck isn’t smoking but I plan on driving 9 hours to Chicago and I want to be on the safe side. Is it normal for that hose to be hot and tight? Can’t open the radiator cap but the gauge doesn’t show over heating. Can I please have some assistance asap?
Elzie-
Thank you for asking about your Ford Explorer. No, that hose is not normally hot and tight. Based on your description, it sounds like the cooling system isn’t getting proper flow. This could be attributed to some kind of a restriction in the system, faulty thermostat or a faulty water pump. We recommend looking into these parts first. A cooling system flush would be beneficial if there is indeed any restriction or something else clogging the system. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 14 Ram Ecodiesel. Just turned over 170k miles. No problems at all until recently. I notices my radiator cooling fan spinning up and after inspecting the system found the water pump was dripping slightly. I took the truck in to the shop and they replaced the Water pump. Since then I have had temperature fluctuations(10 -30 degrees), loosing coolant and higher than usual temps. No over heating yet. I think the highest temp was 233 Deg F.
I cant see the water leak, but have added 3x now. prob at least a gal ea time. Exhaust looks ok. Runs good no missing. Great economy still. Not sure what to do now. Last night got hotter than any other time , Lucky I was at my destination and was able to shut down. Any comments welcome.

My 2002 Honda Civic keeps overheating. Replaced the thermostat, and radiators only 2 years old. Overheats going uphill, and stays around 3/4 of the way up on the heat gauge. I don’t know much about cars, as you can probably tell, but I just need some advice as to what I should do?

hi my vg30e engine is overheating only when driving over 70km. If i drive at 90km for about 10 minutes, the temperature goes pass the half mark. I will continue driving but at 70km the temperature drops under half when the engine is cool. Even after checking the radiator, it remains full. What could be the problem?
Naresh-
It sounds like the system may be building up more pressure when the RPM’s increase. If you are not noticing a loss of fluid, a good place to start would be to check the thermostat. If it is not functioning properly, it would be time for a replacement. Depending on how many miles are on the vehicle, it is possible that the water pump is to blame as well, as that would control the circulation of coolant in the system.
Thank you!
