I have been involved for many years in restoring my old Plymouth and I ran into a new problem: the lower radiator hose keeps leaking at the block end. It's a very small leak and it might take a few days to develop as a small trace along the hose and dripping at the radiator end. I used a repro Corbin clamp an probably will buy a new one, but it is very tight when installed. I'm thinking of putting a thin bead of silicone on the pipe before reinstalling the hose, I have no other suggestions, so maybe some of you can chime in with better ideas? Thank you guys!
