Re: Deluxe heater

I think so. Wants it reaches a certain pressure thevrest is spilled out. The truck my engine came out of had a 16# cap and the radiator itnis with now has a 19# cap.

Higher the #s the higher the boiling point and that's good right? So how do you guys retain factory heater? Is there a way to reduce pressure towards heater core?
