Engine Overheating FYI
Asked by Michael Jun 28, 2008 at 03:03 PM about the 1989 Chevrolet Camaro IROC-Z Coupe RWD
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.

Good point. If the cap won't hold pressure you can drive yourself crazy replacing other parts and never solve the problem.
check your cap first...then check and see if your fan is coming on
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
Make sure your fan is running. My fan wasn't running. Found out the fan was never getting the messege to turn on. So, I just jumped the relay and have the fun on all the time.
Gary. How did you nump the relay to keel the fan on all the time?
