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 of 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. Remove the bolts and detach the power steering fluid reservoir.
