Regarding my '46 PU, I created the cooling problem when I installed the later inline motor with that low pump, which then lead to the fan hitting just about everything on the front of the engine. So only fix at that time was to go to a much smaller fan with skinny blades and in the wrong location. The easy fix for me was the electric pusher fan out front which did solve the problem of not enough air going through the radiator. Amazingly enough I don't need to use this electric fan much at all but on those really hot days in heavy traffic. But if you have a clapped out radiator all the fans in the world will not be the fix. Best of luck
