Antifreeze smell in car

I'm smelling antifreez in the car after running it for atleast enough time for the temp to be straight-up normal. The car dosen't indicate any signs of overheating OR have the smell outside the cabin. I live in MN and didn't start noticing this to after the weather started to get colder this last fall. I once was told that the car had left a puddle of antifreeze where I had stated and let it warmup but checking the coolant lvl and the dipstick show no indication of anything out of normal.

Your heater core is bad. It will not leak very much anti_freeze but it will get worse. And can try a raditor stop leak but i would change it.

No heat blowing cold air.


Do you smell coolant inside of the vehicle. If so then chances are your heater core is going.

Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?


check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

When i start white smokes comes out why


mine does the same thing.. it is a sign that you are burning oil kiddo..either that or antifreeze is finding its way into the engine through a crack or bad gasket.. check for oil smell and moist soot at the tailpipe, or a sweet smell if antifreeze..now if its a steam like smoke..thats normal byproduct of the burning fuel and goes away once the exhaust pipes and muffler heat up enough to blow out all the condensate water...

1992 Toyota Celica - coolant spraying out of overflow, fan didnt seem to be going on. Smells like coolant, so dont think that it is the head gasket. Temperature gauge going up now, but not at first....


There is a fan coolant temperature sensor on the bottom of the radiator, it has an electrical connector on it, with the key on disconnect the connector, if the fans run constantly with the connector off replace this sensor.

There is white smoke coming out the tailpipe no smell of antifreeze


If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

I have a 1996 Ford Explorer, the temp gauge goes up just a little bit above normal that is when I smell antifreeze and I get a little bit fogged up and film on window then it goes back down to normal. And...


You should look under the dash on the passenger side to see if there is any evidence of antifreeze on the bottom of the heater plenium. What usually starts as a small leak in the interior of the plenium will eventually lead to the heater core leaking all over the interior. You are getting steam and the smell becasue the is a small leak now inside that enclosure with the subsequent results.

My truck has a smell of antifreeze inside.The cooling fluid level has not dropped at all.Can't find any leaks on floor board and windows are not steaming up.any ideas


Even though you do not feel antifreeze on the rugs. The only way
the smell of Anti freeze can get in the cab is, It's leaking from the heater core.
Maybe not enough to see a leak on the floor.
However, the heater core is inclosed, plus antifreeze will not
dry. it can sit at the bottom of the heater box, for a long time.
And the smell can stay in there for a long, long time.

Either its the heater core or the thermostat


your heater core is definitley leaking and your blower is pushing the vapor into the cabin. It will only get worse. You can minimize the smell by not running your heater or defroster, but you wont prevent the coolant from leaking and potentially getting worse. Sorry to say, the core will need pulled and repaired or replaced. Sometimes stop leak additives will solve the problem if its not too severe. I have never been a fan of them, its only a band aid in my view. also if u got pets afoid leeting they smell the antifreeze very toxic can kill pets easily. hope this helps. rate above 4* cheers

Strong antifreeze smell when running the heater in 99 silverado, can't see a leak, strong smell, is heater core bad


Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Smoke coming out vents when defrost is on and temp gauge goes up and down in 1994 Taurus


The fluctuation in the temp gage indicates a low coolant situation. The smoke you see from the defroster vent is actually antifreeze that is leaking from the heater core somewhere and as the antifreeze evaporates from the heat it causes a vapor to produce. You should smell a very sweet smell when you see the vapor. If so it is definitely antifreeze. Find the leak and fix it. Then refill your coolant system to specs and you should be good to go.
