If you are replacing the compressor due to internal damage, you must also replace the accumulator and the evaporator orifice tube. Begin by having the air conditioning system discharged by a dealer service department or an automotive air conditioning shop before proceeding. Remove the drive belt. For V6 models, take out the air duct between the air cleaner housing and the throttle body, and on 3.5L V6 models, remove the right-hand turbocharger bypass hose and the right-hand turbocharger-to-charge air cooler. Disconnect the electrical connector from the compressor clutch field coil, then disconnect the compressor inlet and outlet line manifold from the compressor, discarding the old O-rings. Remove the power steering bracket fasteners and move the bracket and reservoir aside. Next, remove the compressor mounting bolts and carefully take out the compressor. For VB models, loosen the right front wheel lug nuts, raise the vehicle, and support it securely on jack stands. On 4WD models, remove the engine cooling fan and the skid plate under the engine if equipped. Remove the right front wheel and inner fender splash shield. Disconnect the electrical connector from the compressor clutch field coil, then disconnect the Crankshaft Position (CKP) sensor connector and position the harness aside. Disconnect the compressor inlet and outlet line manifold from the compressor, discarding the old O-rings, and remove the compressor mounting bolts to take out the compressor. If a new compressor is being installed, follow the directions regarding the draining of excess oil prior to installation. The clutch may need to be transferred from the original compressor to the replacement. Before reconnecting the inlet and outlet lines to the compressor, replace all manifold O-rings and lubricate them with the appropriate refrigerant oil. Installation is otherwise the reverse of removal. Replace the accumulator and the orifice tube if necessary, and have the system evacuated, recharged, and leak tested by the shop that discharged it.
