Review on Electric Cooling Radiator Thermostat Temperature by Bob Jensen

The temperature sensor is defective, in any case it does not work in the specified temperature range. The rest of the kit might be good value for money, but it's no good without a working sensor. 3/8" and 1/2" NPT (National Pipe Thread) is the standard for commercial installs, not auto, threads don't fit any of my autos. Another problem with these things in general is that they are usually closed. and normally open configurations, and no vendor can provide this information.
