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 CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
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 CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
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 AUXILIARY CLIMATE CONTROL - HYBRID article.
Install a new thermostatic expansion valve and filter. For additional information, refer to AUXILIARY CLIMATE CONTROL - HYBRID article.
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.

NOTE: 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 AND LIFTING article.
Recover the refrigerant. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
Remove the drive belt. For additional information, refer to ACCESSORY DRIVE - HYBRID article.
Remove the 5 RH lower engine splash shield bolts and 1 pin-type retainer and remove the splash shield.
