Its the heater core you smell it on the inside because the fan is blowing it into the vehicle antifreeze is unuswal stuff it forms a mist and becomes air borne even a small leak you will smell with the fan running look for wet spots on the carpet under the core but the mist may be so fine and you wonn;t feel it but this your problem

Blows cold air from heater


Some things it could be but not specific to your vehicle.
Do you smell antifreeze? Engine temps running hot? Has it run hot?
No antifreeze in radiator, when cold take radiator cap off and look to see if it is full. add as needed in radiator and overflow container.
Heater control valve not working properly or inop.
Clogged heater core. Leaking heater core-heater core bypassed.
Heater box door not operating properly or inop.
Vacuum leaks or broken lines/cables.
Intake manifold leaks
Clogged radiator
Could be many things, checks/tests need to be performed to determine the cause either by you or a certified repair shop.

I have a 2001 chevy blazer 4wd when driving my vehicle I start to smell as if my car is starting to overheat my gages are showing normal and there are no visible signs of overheating my windshield and


If you smell steam/water/antifreeze inside the vehicle, then most likely you have a heater core issue. If it is more 'overheating' smell outside of the vehicle, it could be overflow container leaking on hot parts, leaking hose, radiator leak, etc.

I HAVE A 2002 BMW 525I I AM ALWAYS RUNNING LOW ON ANTIFREEZE , AND CAN NOT FIND OUT WHERE IT IS LEAKING FROM. HELP


Hi

i do not know if you have allready done this, but check the carpet under the dash press hard on it and see if it is wet, sometimes the small radiator in the heater ( called the matrix ) leaks due to corrosion, and you cannot see a leak from the outside as it is leaking inside the vehicle, also sometimes you will smell a sweet smell inside the vehicle if there is allot of antifreeze inside but not all the time.

Hope this helps.

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

Windshield on the pasangers side of my 2004 freeestar is foging u and i smell antifreeze


Are you sure it is antifreeze you smell? Is it a burnt smell or a sweet smell.
Could be the difference between radiator problems and that of a water
pump? Is vehicle running hot?

Burning smell when running car ? Oil or electrical ?


open the hood and observe the smoke(if any) electrical smell will show a yellowish color with a blue/green/red yellow flame and it moves fast..oil smoke and antifreeze smoke(vapor really) will sort of "steam" off from near the area its leaking from when hot.. brake smell and clutch smell are almost the same since both use like materials for friction..keep an eye on this for potential problems and may need to move the vehicle outside so if it goes up in flame the house wont/grarage whatever//

How to check for leaks of antifreeze/in 97 expedition smell of antifreeze


Hi Sharlene,so you smell antifreeze.Raise your hood and check your antifreeze over flow container,you should have a l and a h mark on it,high and low.If low,then it's leaking somewhere,look at the radiator cap and overflow hose for leak,look at over flow container for leak from hose going to it from radiator,look all over engine,look at top and bottom radiator hoses and clamps for leaks,if leaking there,tighten clamp with flat head screw driver,if no leak is found,get under vehicle and see if any antifreeze is visible,maybe water pump,look on ground for leak and follow,check floor board on driver side,heater core could be bad,check hoses going to heater core from engine firewall.

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

Found a leak coming from the outside grill and runs down the inside and into my drivers well , can you help


If there is a leak getting into the passenger compartment from the 'firewall' it usually indicates a leaking heater core. Smell the leak and if it smells like antifreeze it is the heater core. If it has no smell and is clear then the drain tube from the defroster vent is plugged up causing the condensation from the AC/defroster to leak inside the vehicle.

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......
