needs a new thermostat

I'd like to know the engine temp in degrees F? Does the coolant reservoir fill up in a hurry, does it boil? Does the radiator fan work? I agree with Thomas, it could be the thermostat? It could be the water pump or your getting combustion gases in the coolant, a gasket problem.

Very low coolant level is a possibility but a sticking thermostat is my guess.

i've had a water pump go out around that much miles.. check the bottom weep hole. i'd go with a thermostat change too. it is time.
