Heater core problem?

The heat barely works, the inside of my windshield is usually icy, and my antifreeze is always low and smells burnt. Is this the heater core and where is the heater core? How do I get to it?

I smell antifreeze when the heat is on. The inside of the windshield is fogging up and will not clear and I am starting to get smoke coming through the vent. I have a 2006 Pontiac Torrent


usually this means a faulty heater core. mechanic labor guide calls for 5.2 hours plus an ac recharge. the dealer list price for the part is $190.10 plus anti-freeze.

Theres oil mixing with my antifreeze,why i smell antifreeze inside my car while driving


You could have two problems. First, does the engine require more oil than usual, is the oil level always low ? Does the transmission lose oil ? Could possibly be the trans. cooler in the rad. is cracked. Usually with a blown head gasket you get coolant into the engine, or burn it. ( white smoke ) Has the engine ever over heated ? On the smell part, this could be the heater core is leaking. Have a pressure test on the rad. to try and help find the problems.

It isn't heating correctly and i smell antifreeze. How do I check and replace a heater core in it?


If your heater core was leaking you would have antifeeze coming thru your vents and putting a greasy film on your windshield. You would smell antifreeze the stongest if it was leaking onto a hot engine part. low antifreeze will cause bad heater performance, I would check by the thermostate housing, and the water pump for leaks

Wasn't no problem with untel i replace my water pump. as i finish the water pump job i turn the truck on and feel it up with antifreez and at same time i turn the heat on and smell of entifreez comes out...


You have an antifreeze leak. Probably in the heater core (a small radiator inside of the dashboard that heats the air as it passes through). When the engine is running do you see any steam around the engine? Or smell the sweet antifreeze smell around the engine? If not then it is probably the heater core instead of a hose or somewhere on the engine. Does this truck have the option to switch the heater to recirculate he air inside the cab instead of drawing in outside air? If it does then you can set it to recirculate the air inside and if it still has the smell then its definitely the heater core. Often with a leaking heater core the passenger side floor and firewall area will get wet, but not always.

Steaming from back of the engine. no heat. windshield fogs in the inside


If you are loosing coolant and you see water under the car after sitting you have a leak. The most likely area is the heater core as you are getting steam inside the car. If you smell anti freeze that is another confirming item. Check all the hoses and connections first before replacing the core. Good luck.

Heater core or blower motor?


Sounds like your blower motor , you heater core is a non mechanical part and if it were the issue you are correct in thinking you would see fluid on the floor or mist on the windshield.

Heater works but defrost fills inside with fog.


your heater core has probably sprung a leak.does the fog smell kinda sweet?....check the floor in the front where the floor mats are for moisture or even puddles of antifreeze.(the replacement of a heater core can be very expensive as the entire dash usually needs to be removed to access the heater core)also look under the engine near the firewall for antifreeze drips.

Need to flush the heatercore


your heater core has gone out, thats why there is no heat and thats from leakage of antifreeze. Usually when you can smell burnt antifreeze it usually points to a blown head gasket or cracked head, smell your exhaust and if you smell antifreeze theres your culprit
