I have always put a lower pressure radiator cap on my engine when I get a new vehicle. I usually put a 7 lb. cap and I have never had a radiator leak, heater leak, or split hose. Do any of your do that to your engine?

no and i dont recommend it. i think its supposed to be at 13psi. i have never had a leak in my car and shes an old girl

why would you do that.. you are going to lower the pressure , which will lower the boiling point,easier to overheat..

must not get very hot where he lives......if it did his cacr would overheat on a daily basis.....
