REMOVAL AND INSTALLATION

A/C Condenser Core

Removal

NOTE: Replacement of the suction accumulator/drier 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/drier.

NOTE: If an A/C condenser core leak is suspected, the A/C condenser core must be leak-tested before it is removed from the vehicle. Refer to Section 12-00 for the leak test procedure.

  1. Discharge the refrigerant from the A/C system at the service access gauge port valve located on the suction line. Observe all safety precautions. Refer to Section 12-00.
  1. Disconnect the cables from the battery (10653) and remove the battery hold down clamp (10718) and the battery .
