Yeah I checked it and it opens and closes. I just put in a new one that's 180* where old one was 195.
When I hit engine with IR thermometer the corner of the rad tank(where the engine coolant enters) I was reading about 196*, at the manifold right below chrome thermostat housing reading about 185*, but now if I shot the temp sending unit(manifold mounted) or right below it was reading 215-220*
