Re: coolant leaking from upper and lower rad hose connections

New hose and clamps is what you need. Old hose with rust embedded may never seal. Old clamps are often troublesome, too. My '37 120 C uses 1 1/2" ID straight hose on the lower hose and steel elbow, and the upper hose was 1 1/2" ID straight hose. I replaced the upper hose with 2 short lengths of straight hose and a piece of 1 1/2" exhaust pipe. That exposes another 22 square inches or so of metal to the air for a little added cooling surface. I'd avoid using flex type hose on these cars, especially on the lower hose.
