A/C Compressor Removal/Installation - 2.3L

CAUTION:
  • When installing a new A/C 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 the flushing of the air condition system prior to installing a new air conditioning compressor.
  • If A/C flushing equipment is not available, carry out the filtering of the air conditioning system after a new air conditioning compressor has been installed. See A/C REFRIGERANT SYSTEM FILTERING AFTER A/C COMPRESSOR REPLACEMENT .
  • Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure. SeeEVAPORATOR CORE ORIFICE REMOVAL/INSTALLATION .
  • Replace the receiver/drier. See A/C RECEIVER/DRIER REMOVAL/INSTALLATION .
NOTE:
  • Replacement of the 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 the refrigerant system has not been performed, recover the refrigerant; see A/C REFRIGERANT SYSTEM TESTS .
  2. Remove the accessory drive belt from the A/C compressor pulley. See DRIVE BELT REMOVAL/INSTALLATION - 2.3L .
  3. Disconnect the electrical connector.

  6. To install, reverse the removal procedure.
    • If a new A/C compressor is to be installed, the A/C compressor clutch field coil and the A/C clutch plate must be transferred from the old unit. See A/C COMPRESSOR MAGNETIC CLUTCH REMOVAL/INSTALLATION .
    • If filtering of the refrigerant system is not to be performed, lubricate the refrigerant system with the correct amount of clean refrigerant oil. See A/C REFRIGERANT OIL ADDITION .
    • Install new O-ring seals lubricated in clean refrigerant oil.
  7. If filtering of the refrigerant is not to be performed, evacuate, leak test and charge the refrigerant system. See A/C REFRIGERANT OIL ADDITION .
