Engine Cooling problem
1999 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 135000 miles
Engine started overheating. No coolant leaks; water pump working; cooling fans NOT coming on. If vehicle is going 30 mph or more engine runs hot (225-230) but does not overheat, but temp creeps up slowly. Normal temp in the past as been just over 200. Overheats at idle - up to 260. The cooling fans do work because they came on just for a second and turned off once - but do not come on if temp if temp over 230. I am thinking a fan temp switch rather than a fan relay. Any other thoughts?
have the same problem?
