I don’t know if you’ve ever had the opportunity to own a car that was old enough or cheap enough that you had trouble with it leaking into the passenger compartment, but I have. I’ve actually had a few different cars that would get your wet feet if you jumped in after a rain storm. If you find yourself in a position where you’re asking yourself, “Why is my car leaking antifreeze inside my vehicle?” you’ll find that there are quite a few seals and openings into the cabin of your vehicle. This makes finding out where the water is coming from can often be a difficult job.
How do I know if my car’s coolant is leaking?
You can try checking the seals on your doors, especially if you have free standing windows like some Subarus and sports cars have. Make sure the window is rolling up all the way and the seal is well seated in the jamb. You can also check sunroofs and even your windshield seal. Most leaks into the cabin come through your ventilation system. Most cars gather air at the base of the windshield under the back of the hood and draw it from there through the blower fan. Unfortunately this is also a place water likes to collect. Most vehicle ventilation systems have a drain to let the water out of the ventilation box while keeping the air flowing through the blower. Check to see if that drain is disconnected or clogged.
The last thing you can check is to see if it really is water, or if it is an antifreeze leak coming into your car. Antifreeze runs through your heater core which usually sits somewhere behind or under your dashboard, many times on the passenger side. Heater cores are relatively fragile and it’s not unusual for them to acquire small leaks over time. To check if you have an antifreeze leak and not water, dab some up with a white cloth. If it is green, smells sweet or has a slimy feel it’s probably antifreeze.
Some other possible indications you need to stop a leak in the heater core:
- vapor coming from your vents
- a haze or fog on the inside of your windshield
- a sweet small Inside the car
- low coolant light
Due to the location of the heater core, most of the time they are extremely difficult to replace, even though it is a relatively inexpensive part. Due to the difficulty of replacement, repair costs can be high because of the long labor times that are charged. Often times, heat cores can even be difficult for a home mechanic to replace as well due to the number of electrical components that need to be removed and wires that will be left to get forgotten or crossed upon re-installation.
How do I fix my car’s leaking coolant?
The best solution for fixing a leaking heater core is to seal it from the inside out. This process does not require removal of any components, nor does it pose any risk to the rest of your cooling system. BlueDevil Pour-N-Go is the best sealing agent for stopping a leak in your heater core. When your car is cool, add BlueDevil Pour-N-Go directly to your radiator for best results. Next time you drive your car, Pour-N-Go will be circulated through your cooling system by your vehicles water pump. Once your car is warmed up, there will be a temperature differential at the leak point in your heater core. This temperature differential will activate the chemicals in Pour-N-Go, causing a chemical weld at the leak point. BlueDevil Pour-N-Go is suitable for heater cores made of all types of material.
BlueDevil Products can be found on Amazon.com or at AutoZone, Advance Auto Parts, O’Reilly Auto Parts, NAPA, and other major auto parts retailers.

Dear Sr. I had a head gasket leak 2 weeks ago I used the pour-n-go HGS and it work, now I have discover that the car had a bypass on the heater core (Heater Radiator) . Please tell me if the existent HGS in the system can still seal the unknown suspected leak in the core. How long the pour-n-go maintain its effectivity?
I will appreciate your prompt answer before i replace the faulty unit. Thank you.
The BlueDevil “Pour N Go” only reacts to heat one time. Due to the fact that you are experiencing symptoms of a new head gasket leak you would need to reapply the product to stop the leak.

’95 Honda Accord
My windshield fogs up and I have to keep adding coolant. I also occasionally get what looks like dried green coolant flakes blowing out my vents. My floor is dry. This has been going on 2 years. Will this product work to seal the leaking heater core AND without damaging other components?

I have a leak in my heater core. I used pour n go and had my car running for an hour with the heater on full blast. Once I tuned my car off I noticed that the passenger side had coolant all over the floor matt and drenched my carpet. Seemed to be dripping from the glove compartment. Why did this happen? Did the car just drain the liquid? Should I try another bottle? I still hear a leak coming from the vents, however no smoke or overheating. Please help!

Hi I have a grand pri 2008 about 2 weeks ago i noticed something was on the floor of my car on the passenger side I thought someone dropped juice or something so i ignored it however days later i noticed my feet were all wet & so was my purse n i was like what the hell is dripping here? We kept using the car n the other day i literally saw when the liquid was dripping on my foot so i googled it & i found out its the heater core. I dnt have money to buy a new one at this time so i figured i should buy the Blue Devil product but I think its dripping way too fast so will this help? Or should i just do a bypass I need my car asap so please answer

As long as it is not losing more than about 1 quart of antifreeze during a hour run then there is a very good chance that BlueDevil Head Gasket Sealer will be able to seal it.

HI I have a Nissan hard body 3.3 v6, I see the is water cooling coming to my left passenger side and mist on the windshield, it over headed before but never reached maximum heat, the power is still OK, what is the problem?
King,
Thanks for your question about your Nissan truck. We’re assuming the coolant is on your passenger floorboard and you’ve got mist on the inside of your windshield. If that is the case then you’ve got a leak in your heater core that is dripping onto your floorboard and the hot coolant is getting carried through your ventilation and hitting your windshield through the defroster. You can replace the heater core or use BlueDevil Pour-N-Go to seal the leak. If the coolant mist is on the outside of your windshield then you probably have a leak in a cooling system hose near your firewall and should be able to tell which one by opening the hood while your engine is idling and hot.
Thanks again for your question!

Hi i have a 1986 nissan maxima at first i could hear hissing and I thought my radio was acting weird but then 7 minutes passed and coolant smoke was coming through my vents while I was driving then another 15 minutes pass and my whole car was filled with white smoke and some coolant was leaking from the bottom of my car.
Phillip,
Thanks for your question about your Nissan Maxima. It sounds like you’ve got a leak in your heater core. The hissing and smoke would be coming from high pressure and temperature coolant leaking through the heater core into your ventilation system. As the leak got bigger, the coolant would condense and either leak onto your floorboards or out through the condensate drain for your HVAC system. You can use BlueDevil Pour-N-Go Head Gasket Sealer (available here: http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) to seal to leak and get your car back to normal.
Thanks again for your question!

Hey guys….I have a 2006 Ford Taurus and I have leakage into my passenger side cabin floor. The car rides rough when I turn on the heater/defrost, there is an odor, and light smoking from under the hood down around the manifold. I personally changed out the heater core (8 hrs ? thank goodness for YouTube lol) Thought the issue was fixed but the conditions are still occurring. I think I have an oil pan gasket leak as well.
Based on this info, 1) what’s your professional opinion on what could be wrong? and 2) would Blue Devil HGS be useful?
Thanks in advance guys.

Thank you for asking about your Ford Taurus. Based on your description, if the same symptoms are still present, it sounds like you may still have a heater core leak.

GK-
Thank you for asking about your Ford Figo. Are you noticing a loss of antifreeze or refrigerant? If you are losing antifreeze, that would not be producing a hissing sound from the A/C, so the two issues would not be related.

I have some questions about water pump leaking and oil leaking….I am tired of having my car, Chevy Impala 2007 to the auto shop 5 times in one month and I paid for these repairs nearly $1,700 to replacement parts and replacement oil fluids and other fluids. I wonder which one what I needs to buy the product for water pump to stop the leaks…especially…I heard lots of good stories on oil leaking often and used your wonderful product to stop oil leaks!!!!!!!
Sam-
Thank you for asking about your Chevy Impala. Unfortunately, we do not manufacture a product intended to stop water pump leaks. A hard part repair may be your best option. As for the oil leaks, do you happen to know where the leak is coming from? Using the BlueDevil Oil Stop Leak would require you driving the vehicle 100-200 miles before you got the full benefit of using the product, so you would want to get the water pump replaced prior to doing so. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 2015 Jeep Patriot, it is not even 3 years old and it developed a swishing water noise when I would turn left with the Air on. Then I got a hot foot and had to pull off the freeway, I then learned burning hot fluid was dripping on my foot when it was on the gas pedal. The car was undriveable until I made a cardboard/duck tape shield to stop the hot coolant from getting on my foot. When I checked the coolant level it was between add and full. Is this a coolant leak? Have you heard of other near new Jeeps with this same problem (I have under 45,000 miles on this car and most of it is highway). Will your product work and is it dangerous to get on my body as the leak is dripping on my foot without the shield in place?
Elisabeth-
Thank you for asking about your Jeep Patriot. Have you verified if it’s a water/coolant leak or condensation from running the A/C? 45,000 miles is extremely early to be having any kind of a head gasket issue. It doesn’t seem like you are experiencing any of the tell-tale signs of a blown head gasket, so it sounds more likely that the A/C line is clogged. We recommend taking the vehicle to an A/C specialist so that they can unclog the drain.
Thank you!

Hello my 2006 Ford Mustangs check engine light came on when antifreeze came in on the driver side while I was driving. I parked it and I think it is the heater core but what happened to it. But Ford also replaced the heater hose. I just wanted to ask the question before I took it back to them and have to pay for a diagnostic and from 1000 – 1500 dollar to get it fixed can I use this product. And also prior to this happening when I would have my AC on my window would get condensation on it.

I have a opel corsa lite 1.4i 2005
Hot steam comes out from the heater inside the car and then the heat gage would go up. We removed the thermostat and the heat does not come out from the heater anymore but it still loses water. The inside of the car floor is also wet. What can the cause be of this?
Maeve-
Thank you for asking about your Opel Corsa. Based on your description, it sounds as though you may be experiencing a heater core leak. Removing the thermostat would affect the heat coming out, however, water found on the passenger side floor would indicate such a leak.

My 2002 XC is leaking on both sides inside, coolant. It now needs it every other day for small drives. I was about to have a service check and noticed the coolant on the passenger side under the carpet pad. I had transmission work done a year ago when the engine was taken out of the car – It seems to be getting worse!
Dianne-
Thank you for asking about your Volvo XC. Based on your description, unfortunately, it sounds as if you are losing coolant a little too quickly for our products to be effective. The coolant on the passenger side, underneath the carpet, is most likely due to a heater core leak. Having the vehicle properly diagnosed will give you a better idea of what needs to be replaced, and would allow you to make a decision from there.

I have a 2005 Toyota hilux
I can see by looking up under the dash that there is clearly a leak coming from the heater core,
It is dripping about once every second when heater is on, if heater is off it’s drips out the overflow in the engine bay
Is one drip per second to big of a hole for this product to work? Or am I better of just getting heater core replaced?
Thanks
Jack-
Thank you for asking about your Toyota Hilux. Kind of a rule of thumb with the product, the vehicle will 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 minute run. Leaks that are seeping or lightly dripping are exactly the kind of leak the product is intended for. Feel free to contact our technical support line at 888-863-0426 with any other questions.

My 2001 Dodge Grand Caravan Sport is leaking coolant into the driver’s side floorboard , as well as as the motor heats up it is fogging the center of the windshield, and when the motor is good and hot I can hear sizzling / bubbling / crackling and popping sounds coming from the center of my dash. I have enough sense to know it’s the front heater core but I’ve tried Bar’s Aluminum Radiator and Heater Core Stop Leak , K-Seal , and Bar’s Copper Block Seal for larger leaks and none of it has worked. I am having to get water in my van every 2 or 3 days. Do you think it might work to solve my problem? I am checking in advance before dropping any more money on something that might not work or reverting to a method that I’ve used before

Exactly the problem I am having right now. The coolant leaks inside the car but only when it rains!
I took it to my mechanic and told him that the coolant is leaking but I didn’t mention it’s happening only when it rains (as I wasn’t sure the first time it has anything to do with the rain), so he couldn’t find anything either but with his experience, he turned off the heating system (I was okay with it as I hardly ever use it). And after almost a month, it rained again and I have the same problem.
Brilliant and accurate post, this will help in identifying and rectifying the problem.

Hi guys. I observed coolant leaking into the driver’s side floor of my Camry 2007. Plus foggy mist/steam in my windshield. What could be the cause
Anthony-
Thank you for asking about your Toyota Camry. The symptoms you’ve described would be a tell-tale sign of a heater core leak. The BlueDevil Head Gasket Sealer would be able to treat a leaking heater core. As long as you aren’t losing water/coolant too quickly, you would be a good candidate for the product.
Thank you!

I have a 2010 Chevy Equinox with all the symptoms of a heater core leak. Including fluid on the passenger floor board. I plan on using the Blue Devil Head Gasket Sealer as a temporary fix, however, the instructions on the bottle is recommending a chemical flush. Is this a true requirement as I have not seen any comments above regarding a flush to be performed prior to using this solution. Please advise. Thank you in advance.
Best regards,
EF
