Question about 1997 Pontiac Grand Am

Anti-freeze smell On my wife's 97 grand am (4 cylinder), when the heater is turned on the smell of anti-freeze comes from the vents. I'm lost on the possible cause so I can fix it.

    Would it be a leak that I would notice under the vehicle? I haven't noticed any and this vehicle gets parked in the garage.

Hi you wouldnt notice it under the car but inside where your feet go check the carpet for damp, it may only be a small leak but enough to get the smell in the car,

I see a misty smell like anti freeze coming through the vents in the car


Holy cow you can see smells?????


haha just messing. If you have the smell of anti freeze coming through the vents it means that the heater core needs to be replaced. The heater core cycles the hot engine coolant and uses that to warm the air to give you hot air. If you can smell it it is leaking into the vent system and needs to be replaced.

After I drive my 1999 boxter the pasenger side exterior vent smells like a radiator and vapor comes out.


This is most likely leaking anti-freeze from the heater coil. Radiator Stop-Leak may help but replacement will likely be expensive. When replacing the heater coil, don't fail to rinse the plenum thoroughly. If you don't do this you will forever smell the anti-freeze....It does not evaporate ! That's why it is used. In the thirties and forties, alcohol was the anti-freeze of the day and it boiled off rapidly....results sere seized engine blocks or frozen systems. Thanks to DuPont for Prestone. Take care, Paul

Bad odor (Wire sheathing?) from vents when fan is on. We definitely have an intermittant (3 or 4 times in past year) driver side actuator problem. Cannot tell if odor is coming from all vents or not....


the heater core is bad it could be leaking and thats what the smell is coming from. you only smell it when the heat is on is because air flows throught the heater core to warm it by the hot anti freeze that flows through the heater core see if you anti freeze resivoir is low.

Cold weater start problem. Oil smoke in from the heater vent.


The same problem happened to me and it turned out to be my heater core.

Normally smoke will come from the heater core when it needs to be replaced.

Also the smell is most likely anti-freeze and and you normally smell it when your
engine is running warm or hot.

Check your coolant levels to be sure. and the hoses leading to your Heater Core

heater cores for that vehicle normally run $180 - $230 and you need to remove your
entire Instrument Panel (IP) (Dashboard) to replace it.

I hope this helps!

??? heater core


If you smell antifreeze, the problem would be the heater core.
Another indication is when you turn on the defroster and see a oily film on your windshield.
The heater core would have to be replaced.
In order to do this the whole dashboard would have to come out to get the heater box out.
In a dealer the process would take about 4 hours from qualified mechanics who have done this before.
