R-RACER 43. The engine in question ,new from factory , heated continually untill I decided to change the thermostat as a first option fix. When I removed the thermostat housing there was NO thermostat. I installed the proper rated thermostat and the engine never heated again. That was all that I did. It is obvious that the coolant was circulating too fast to cool. If coolant leaving the radiator is hot the temperature will only rise through the engine and the process continues. If you can provide a more rational explanation , others and myself would like to hear it. My previous post was not just an old wives tail. Due to the reduced size of the orifice in the thermostat it will naturally reduce the flow even when opened fully.
