I had to replace the water pump on my 1950 TO20. I ordered all the parts from this site. It didn't have a thermostat or temperature gauge so figured if I was tearing it apart Id change the coolant,pump, and add the thermostat and gauge. The pump went it fine. I installed the thermostat according to service manual. The problems I'm having is the probe and nut that go into the neck for the gauge seeps it feels tight but it keeps dripping especially prior to the thermostat opening seems to stop or slow when thermostat opens. Problem 2 is I filled system with water to test everything prior to switching to antifreeze and seemed to work well however once it reached temperature and thermostat was above 180/200 it seamed that the temp would rise quickly on the gauge and then it would come out overflow the temperature would then drop and be back to normal. Was this the systems way of eliminating excess water? Any help or suggestions are appreciated especially on the gauge probe.
