Re: 327 Running Hot Please Help
As Jim stated a bad radiator cap will not cause it to overheat, it will affect the temperature at which your coolant boils. For example : straight water boils at 212*. If you now have this system under pressure, it will boil at a higher temperature. This is why you hear nascar racer's say the water temp. is 240* and this is fine. They are probably running a 22 lb. cap.
