I visited a club member this evening who is installing a new touring engine from AER and a 4 speed transmission. He also ordered a new aluminum radiator for the Model A with the recovery tank designed to be pressurized. The radiator cap that came with it looked of lesser quality and did not have a pressure rating on it. I suggested he make the call to find out the caps pressure rating. This got me thinking, what psi cap should be used when one chooses to pressurize? Of course he doesn’t really need a hopped up cooling system, but since he can and he is having fun, it’s going to be a pressure system.
