My 2002 Pontiac Grand Am GT runs hot. The fluids have been changed and are full, spark plugs recently changed as well as oil and air filter. Check engine light not coming on. Even upgraded gas grade. Any ideas?

    You either have a Bad Water pump and its not circulating the coolant through the engine, or your thermostat is not opening to allow the coolant to release the heat through the Radiator. Also there could be air in the coolant System. Any of these can cause your engine to run hot and not set a DTC or Check Engine Light.

    Another very common cause is a blown head gasket. The combustion gasses displaces the coolant. Do you notice coolant loss and is there odor in the radiator....

    your water pump could be bad.... usually check engine light won't come on for that.
