Engine OverHeating FYI

10,315

Asked by Jun 28, 2008 at 03:01 PM about the 2000 Pontiac Grand Prix GTP

Question type: Maintenance & Repair

It absolutely amazes me how many people are having problems with overheating and yet nobody suggestes changing the radiator cap. If the radiator cap is not functioning properly it allows pressure to be vented from the cooling system prematurely causing a lower boiling point. This then causes the engine to overheat. This is a $5 part on most vehicles.
