I'm trying to locate a replacement radiator cap and a reputable rebuilder for the water pump. After replacing the radiator, overheating is still an issue. I suspect the cap ( looks like someone tried to make a new rubber seal) and water pump. Any help or suggestions is much appreciated. Thanks in advance!

As for the radiator cap, Bob's Automobilia in California




is primarily for Buick parts, but they know Cadillac, and which pieces will solve the problems.  My 1941 Cadillac had a typical radiator cap, and I did not know that one with a longer depth was needed until Bob was able to supply it. My car used to push out coolant because the system was essentially "open" rather than pressurized. Now, thanks to some careful examination, and parts from Bob, the problem is solved and the Caddy has run cross-country several times without running hot.
