over heating on the free way.
Ever time Im on the free way my car over heats. I have a new radiator, water pump, engine, and hoses. So what do
you think it could be?
My guess since it only happens on the highway would be air in the system. A sticking thermostat will ussually over heat in any situation. Try taking the radiator cap off and letting the car idle a good while see if any air gets out.
