Hi David How come you're not running a thermostat? With a thermostat installed, would it allow the water a little more time in the radiator to cool down rather than having the water circulate through the motor continuously...........possibly preventing the overheating problem? Not sure if I'm correct here or not......anyone else agree/disagree?
