I'm slowly going through this 1947 BDH I acquired. I thought I'd check the thermostat and the manual said it should be in the housing leading to the upper radiator hose. I took it off and there wasn't a thermostat. Neither the housing nor the coolant manifold has a shoulder cut into it for a thermostat to be inserted. Am I looking at the right place or is it somewhere else on the engine? Also, can this thermostat be picked up at a parts store like NAPA or is it a special order item? Thank you.
The thermostat should be half way along the hose between the radiator and the water mamifold on top of the head, it is not like a conventional thermostat, it is a cylinder of grater diamiter than the hose with a step down at either end to fit the hose. I would try Zimmermans. Sam
Thanks for the info. I see in the one picture in the manual that shows the upper hoses a small can-like item between the hoses. Mine right now is just a empty tube. I did some research on the internet and found a Gates part number for this thermostat. So hopefully its available. Thanks again.
