Q: How to remove and install an automotive air conditioning compressor?A: Have the refrigerant discharged at a dealer service department or an automotive air conditioning repair facility. Disconnect the cable from the negative terminal of the battery. Loosen the right front wheel lug nuts. Raise the vehicle and support it securely on jackstands. Remove the right inner fender splash shield. Remove the splash guard underneath the engine. Remove the fresh air intake duct. For 2.5L engines, drain the cooling system. If the coolant is relatively new, or is in good condition, save it and re-use it. Disconnect the upper radiator hose from the radiator. Disconnect the overflow hose from the fitting by the radiator cap. Remove the drivebelt and, on 2.5L engines, remove the alternator. Disconnect the electrical connector from the air conditioning compressor. Remove the fasteners holding the hose and pipe terminals to the air conditioning compressor. Disconnect all refrigerant lines from the compressor. Note: Plug all open fittings to prevent entry of dirt and moisture into the lines. Remove the compressor mounting bolts and remove the compressor from the engine compartment. Note: If a new compressor is being installed, the clutch assembly may have to be transferred to the new compressor. The removal of the clutch assembly will require the use of several special tools; this procedure should be performed by an air conditioning shop or dealer service department. Installation is the reverse of removal. Tighten the compressor mounting bolts to the torque value. Note: Do not use old O-rings for the refrigerant lines, replace them with new ones and apply compressor oil to them before installation. Reconnect the battery and perform the necessary re-learn procedures. Have the system evacuated, charged and leak tested by the shop that discharged it.
