Excellent Radiator Coolant Cap

This Radiator Coolant Cap is great. Other brands are cheaper however only provided 15 P.S.I. which means it will fail quickly. Do you have a cap that spins and is difficult to remove or is damaged. The problem is the cap must be 18 P.S.I. Buy this one. Highly recommend.

standard pressure caps kept breaking

Got the high pressure one because the standard pressure ones kept breaking. Headgasket is good no combustion gasses or oil mix. No more 3/4 temp gauge now alls good.
