Engine Cooling problem
2000 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 220, 00 miles

I bought this car from the original owner with 212 K miles. Only known problem at purchase was slight coolant leak. This has become a problem of overheating frequently, requiring a jug of Dex-Cool in the trunk always. Leaks can't be seen, but you can smell anti-freeze. Mechanic changed water pump and thermostat to no avail. Interior heat is not very good on highest setting. When driving you can smell anti-freeze, but if you put the air selector on recirculate (MAX) the smell is gone, so it must be coming from under the hood and sucked in by the blower. Just today I spoke to a friend who said his daughter had the same car and Pontiac has an un-advertised warranty to change the head gaskets to fix this problem, which they did on her car at no charge. He said mileage is irrelevant for this warranty.

Do you
have the same problem?

I'm not familiar with the headgasket warranty scenario. This may also be an intake gasket leak.

Becareful that the leak doesn't get bad quick and fill up a cylinder. IF the motor hydrolocks because the piston is try to compress liquid, then it can junk the motor.

Was this
