CAUTION: If installing a new A/C compressor due to an internal failure of the old unit, carry out the following procedures to remove contamination from the A/C system.

If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM FLUSHING .
If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor is installed. For additional information, refer to REFRIGERANT SYSTEM FILTERING FOLLOWING AIR CONDITIONING (A/C) COMPRESSOR INSTALLATION CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS .
Install a new evaporator core orifice. For additional information, refer to EVAPORATOR CORE ORIFICE - HYBRID .
Install a new passenger zone valve. For additional information, refer to PASSENGER ZONE VALVE .
Install a new battery zone valve. For additional information, refer to REMOVAL AND INSTALLATION .
Install a new thermostatic expansion valve and filter. For additional information, refer to REMOVAL AND INSTALLATION .
Install a new suction accumulator. For additional information, refer to SUCTION ACCUMULATOR .
Install a new auxiliary thermostatic expansion valve (TXV) filter. The auxiliary TXV filter is located in the auxiliary evaporator inlet line at the auxiliary TXV inlet connection.

NOTE:

Installation of a new suction accumulator is not required when repairing the air conditioning system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the suction accumulator.
If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
Recover the refrigerant. For additional information, refer to REFRIGERANT SYSTEM RECOVERY .
Remove the drive belt. For additional information, refer to REMOVAL AND INSTALLATION .
Remove the 5 RH lower engine splash shield bolts and 1 pin-type retainer and remove the splash shield.

Remove the compressor manifold and tube assembly bolt and position the A/C manifold and tube assembly aside.
- Discard the O-rings.
- To install, tighten to 21 N.m (15 lb-ft).
Disconnect the A/C compressor electrical connector.
Remove the 4 A/C compressor mounting bolts and the A/C compressor.
- To install, tighten to 25 N.m (18 lb-ft).
To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. For additional information, refer to CLUTCH AND CLUTCH FIELD COIL - HYBRID .
- Install new O-ring seals.
- If not filtering the A/C system, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to REFRIGERANT OIL ADDING .
Evacuate, leak test and charge the refrigerant system. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
