To remove the air conditioning system, start by having it recovered by a dealer service department or automotive air conditioning shop. Then, loosen the lug nuts on the right front wheel and raise the vehicle on jackstands. Remove the wheel, as well as the right front fender splash shield and engine splash shield. Take off the drivebelt and, for four-cylinder models, remove the mounting nut and stud from the rear of the compressor. Disconnect the electrical connector from the compressor clutch field coil and the inlet and outlet lines from the compressor, discarding the old O-rings. Remove the compressor mounting bolts and take out the compressor. For V6 models, on 2015 and later 3.5L models, remove the cooling fan shroud assembly. Then, follow the same steps as for four-cylinder models to remove the compressor. To install a new compressor, drain excess oil if necessary and transfer the clutch from the original compressor. Replace all O-rings and lubricate them with refrigerant oil before reconnecting the inlet and outlet lines. Finally, reverse the removal steps and have the system evacuated, recharged, and leak-tested by a professional shop.

For four-cylinder models, you should remove the mounting nut and stud from the rear of the compressor. Disconnect the electrical connector from the compressor clutch field coil and the inlet and outlet lines from the compressor, discarding the old O-rings.
