Engine Overheating FYI
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.
Good point. If the cap won't hold pressure you can drive yourself crazy replacing other parts and never solve the problem.

you must also make sure that there are no air locks in the cooling system... i bought a snap on cooling syster tool that draws the cooling system into a vacuum, then you suck the fresh coolant in..... works like a hot damn
