Engine Cooling problem
1995 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 126000 miles
The fan relay is fine, the fan motor was replaced. But the car is still over heating. There is an audible knocking noise coming from the cooling system itself. The engine heat will spike past 220 then for what seems like no reason it will suddenly just drop down to normal operating temp of about 160. Any Ideas?
have the same problem?
