My 1/4 npt sensor came today and fits nice, thanks for helping with the thread numbers.
While I'm in the minority here regarding sensor location, however I'm quite convinced I'm correct. The contra opinions caused me to think about it. Radiator cooling happens from the fan OR from car speed OR both, even depending upon outside air temperature.
The radiator must provide cooling of the water which enters at the top and exits at the bottom. At highway speeds on a cool day moving air provides adequate radiator cooling and the electric fan just isn't needed. Placing the sensor at the outlet of the radiator works properly for that condition. Placing the sensor where water is always hot doesn't cover the high speed cool day situation.
I will report results once I get the car on the road with it's new engine.
