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 the 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 (19D990) as directed by the A/C flushing or filtering procedure.
  • Install a new suction accumulator (19C836) 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.
