i want to change my radiator cap and have searched for info on what to use, but different info everywere, so im confused? my car is a 1979 308gtb euro and i think it should be a 4 "ear" cap, also diffrent info if i should go with 0.9 or 1.1 any info on this will make me happy.
I believe the original was 0.9 bar then Ferrari updated it to 1.1 bar. My QV originally came with 0.9 bar and also updated to 1.1. bar and it works great.
Here is more than you would ever want to know. (BTW, you want a 1.1 bar cap.) The 308/328 Coolant System – Anatomy of the Expansion Tank Cap
