Since the Fan comes on at proper temperature, it can't be the sensor or the relay, but the engine still steams up, the radiator holds pressure, no leaks.
I think it odd that the plastic reservoir did not overflow when the engine over heated, and I don't think its the radiator cap pressure. I don't know how to test the thermostat without removing it. And I wonder if the water pump and/or the thermostat is likely or rare?
