Which Radiator Cap??
Can someone please explain to me the differences in lb ratings on radiator caps?? ie: 16lb cap, 14lb cap....huh?
My current cap is leaking and I want to know what correct one to use now. I have a mild (400hp) 355, with an edelbrock water pump and a griffen radiator.

higher the pressure, higher the boiling point.

You normally would want the highest rated cap that your cooling system can handle without leaks. I'd start with an 18 lb cap.
