Radiator Cap Question

Post by robert1959fury »

I have a 59 Fury with the rare factory air conditioning that I recently purchased. The radiator cap is rated at 13#, which I"m not sure is correct. My shop manual states that most of the cars came from the factory with 14# caps.

Since this is a facotry A/C car with the appropriate radiator size, shroud, and fan, should the cap be rated at 16#? I have not been able to find a proper answer, so any help would be greatly appreciated-Thanks!

Dick has been having some communication issues lately (email, text, phone) - but finally today he's back! I had a conversation with him just now; he tells me 13 psi is what he runs in all his A/C systems, even his '59 DeSoto. He says not to worry!
