CAUTION: If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning 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 has been installed. For additional information, Refer to REFRIGERANT SYSTEM FILTERING AFTER A/C COMPONENT REPLACEMENT .
Install a new thermostatic expansion valve, as directed by the A/C flushing or filtering procedure.
Install a new receiver drier (19C836) as directed by the A/C flushing or filtering procedure.

NOTE: Installation of a new receiver drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the receiver drier.

NOTE: New O-ring seals, lubricated in clean PAG oil, must be installed before reconnecting any A/C fitting that has been disconnected.

Recover the refrigerant. For additional information, Refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
