Carefully release cooling system pressure by turning radiator cap to first stop. Tighten radiator cap. Drain cooling system. Disconnect heater hoses and plug hoses. See Fig. 1. Remove glove box for access. Remove Rear Anti-lock Brake System (RABS) module mounting screws and move module aside. Remove 7 screws attaching heater access cover to plenum. Disconnect vacuum source.
