I am in the last stages of assembling my Model T. Just got the radiator on and am installing the rubber inlet and outlet hoses. I have been messing with Model T's and been a backyard mechanic for 40 years, so you'd think I would know such a simple question, but I have never seen this asked so at the risk of appearing totally clueless I need to ask for myself and, perhaps others:
Question: The radiator bottom outlet and top inlet and block outlet and inlet have a ridge around them. When installing the original type hose clamps (with the screw and square nut), where is the most efficient point to position the clamp to ensure the best seal? On top of the ridge, or between ridge and the end of the hose?
I have always positioned the clamp as close as possible to the ridge, between the ridge and the end of the hose and have always gotten good seals, but I'd like your opinion. Thank you. Jim Patrick
Jim, I think that's how to do it. Place the clamp next to the bead on the side away from the coolant. That way, for the hose to blow off it would have to stretch the clamp to slip over the bead. Just my $.02 Happy T'ing. Bob
Look in the Ford Service Book. There are plenty of pictures in there to show you exactly where to have your hose clamps.
Smear some (not too much!) RTV on the outside of the item the hose is sliding onto. It will make the seal very water tight.
Makes 'em slide on easier too.
Henry never used RTV...
and here we go...
After a slight leak on the radiator side of the lower hose I also used RTV. Made for a much easier installation too. The clamp should not be on the bead but close to it. Screw head position is whatever is easiest for you but they do look better if their all in line.
