A/C Compressor Removal/Installation (2.3L)

WARNING: This page is about a different car, the 2002 Mazda B4000, 2002 Mazda B3000, and 2002 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
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 REFRIGERANT SYSTEM FILTERING AFTER A/C COMPRESSOR REPLACEMENT  .
  • Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure. See EVAPORATOR CORE ORIFICE REMOVAL/INSTALLATION 
  • Replace the receiver/drier. See 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 REFRIGERANT SYSTEM TESTS  .
  2. Remove the accessory drive belt from the A/C compressor pulley. See BELT ROUTING .
  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 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 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 REFRIGERANT OIL ADDITION  .
