    I have a 02 gtp with 80000. I am losing coolant but without any noticable leaks. About every 3 months the light comes on(yes I have replaced the sensor) and I add maybe a 1/3 of a gallon and lights out. I have had the system pressure tested cold and hot. Holds good pressure either way. No milky build up on dip stick no smells. Has me befumbled. anyone else have any suggestions?

    Lower Intake gaskets ever been changed? You probably need some new ones...thy are ac common issue with these cars. It'll just slide right by the gasket into the motor...which isn't great on the bottom end.
