which thermostat for my 1953 dodge B4-HA 25" chrysler engine

[Ray J.]

I searched so many threads I got eye strain trying to find which thermostat fits my engine.

Does anyone have a part number for one?

This is the housing on the engine. There was no thermostat in the housing.

Thanks

   I have a 49 Chrysler with a Spitfire head. I used a Stant 13928 thermostat. I bought it from Rockauto several years ago. They sell a Motorad 400580 now. NAPA THM 155, Gates 33028, are a couple other numbers. It has to have the top rubber seal. You have to use thread sealant on the housing bolts, they go into the water jacket, the same as the manifold, head and water pump bolts. Your other post said that you cleaned the head with Evaporust. What are the first three digits of the engine number, on the top of the block? My engine is C45. Keeping all your posts to one thread is easier to keep up with your project. If you buy from DCM, a C-513 is the thermostat and the lower outlet tube is C-152. If your engine number is C52, it’s a 265 c.i.

Thanks for the info. I did not see how one of those big ones I saw on Ebay would fit in the housing.

My engine serial number is C51-73604 which is a 250.

Being new to the forum (and old) I could not figure out how to keep it in one place, but now I have it figured out.

Thanks again.
