Erica This is great information! I was told that my airconditioning belt was the cause of my car overheating and a few other things you listed in this article and I do not run the aircondition in my car. Someone was trying to rip me off. 9/5/2005
bart how do you check a thermostat? 8/13/2005
Joseph My old 86 ford laser keeps overheating. You said 'If the radiator cap does not hold pressure correctly then coolant could boil and therefore the engine would overheat'. when my car overheats the coolant usually does boil. Do you think that it's most likely that there is a problam with the radiator cap or is it more likely to be something else.

if it's possible could you get back to me on this by e-mailing me at jawk99@uow.edu.au

thankyou
