And why is she overheating anyone know calling the service dept tomorrow morning if anyone has any idea's or info please let me know thanks.
Did you hear/see the radiator fan kick in at all? If not check the wiring to the fan control module (the gray finned metal box 6"x4" on the RH inner wing behind the headlamp). If you have water in the header tank I don't think you are loosing coolant.
