Ok here goes my question. My radiator does not over heat nore does my temp idle raise on the gauge due to temps rising but. Everytime I shut off the car it makes a sizzling noise. So I pop the hood and it seems to me that antifreeze it kinda leaking from the top of the raiadtor. Or maybe condensating out no where nere the radiator cap. Could that mean that I have cracks on the top of my radiator. Can some one please help me. I need to knmow if I have to replace my radiator.
