AIR CONDITIONING (A/C) COMPRESSOR

Removal and Installation

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.
• Installation of a new suction accumulator 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 suction accumulator.

1. If flushing of the air conditioning system has not been performed, recover the refrigerant.
2. Remove the RH and LH cooling fans.

1. Loosen the tensioner and remove the drive belt from the A/C compressor pulley.

• • If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit.
  • Install new O-ring seals lubricated in clean mineral oil.
  • If not filtering the refrigerant system, lubricate the refrigerant system with the correct amount of clean PAG oil.
