My gauge is Reading 75 Ohms when hot (Hot being C--------'--H) , 71.5 after sitting for 45 Min Its Now Reading C-----'-----H

The thermostat I put in starts at 160F to open its a early one

I was offering values at the factory sender you could compare to thermometer.
I don't know what gauge you have or understand where you are checking.
