thermostat

[oldcarlover]

I have a 1950 flattie in my 36 ply. My thermostat housing is the tall type

with a straight-up outlet to my 36 radiator. I am trying to find the correct

stat to fit.

My understanding is that all thermostats to suit the mopar sidevalve 6 have the same physical size, just different temperature ratings, so any from any 23/25" engine should fit............andyd

Depends on if it is an external bypass or not. In early to mid-1930s the deluxe models typically had an external bypass while the standard did not. He also mentioned that he has a 1950 engine and I don't know if that used an external or internal bypass. A photo would settle it pretty quickly.

Andy there are different ones depending on if you have the stamped steel housing or the cast iron version. I believe from his description that the original poster has a cast one which is a napa thm 55 160° or thm155 180°

Ed, thanks for the info, tho I thought the actual physical size of the thermostats would have been the same.....andyd
