Yes, I was in US Navy Aviation, I never served on a ship, I've never owned a boat and I never will. I have seen some marine application heat exchangers but nothing that would be anywhere near small enough for the constrained spaces Jack has in his lowboy coupe. I got the impression that you were saying that there is a small, compact heat exchanger that could fit in the existing lower radiator hose and do the job while not impacting the coolant flow for the engine.

I'm not adding any value to Jack's quest here, I was just intrigued by the veiled reference to a readily available HX that I'd never seen before. Jack, I hope that you get your problem solved to your satisfaction and if you do that I expect that it will be top shelf work.
