Question about 1999 Pontiac Grand Am GT
Engine overheating. Thermostat has been replaced..There is no water in the oil, and I am not sure where the coolant is going.
'99 Grand Am have a plastic water outlet located on the back of the engine. (Same side as the battery). It is installed using a thin O-ring. Antifreeze is corrosive and weakens the O-ring causing a leak. Because of the location the leak can be almost undetectable. Replace the O-ring, but becareful not to break the water outlet.
