    The radiator may need to be replaced, due to mineral build-up. Phosphate scale will block passages in the radiator and heater core. Afterwards, refill with a 50/50 mixture of antifreeze and distilled water. Read you Owner's Manual if there are any steps to prevent air from forming in the system.

    Aluminum heads are easy to warp, so you need to get this overheating problem fixed before driving it anymore. Otherwise, you could blow the head gaskets and damage the valves.
