Replacing the thermostat on a vintage WW2 Jeep is very easy. Check out this video for a demonstration where I change out a 180 degree thermostat with a cooler-running 160 degree part.
The part number for the 160 degree thermostat is 812050. You can get these from kaiserwillys, midwestjeepwillys, debellajeepparts, and many others.
