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  CLIMATE CONTROL SYSTEM-GENERAL INFORMATION  . 
  • 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  CLIMATE CONTROL SYSTEM-GENERAL INFORMATION  . 
  • Install a new evaporator core orifice, as directed by the A/C flushing or filtering procedure. 
  • Install a new suction accumulator as directed by the A/C flushing or filtering procedure. 
NOTE: 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.
NOTE: If installing a new A/C compressor, the A/C clutch disc and hub (19D786), A/C compressor pulley (19D784) and A/C clutch field coil (19D798) must be inspected and transferred from the old unit to the new unit if suitable for reuse.
