REMOVAL

NOTE: Installation of a new suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from failed A/C compressor or damage to the suction accumulator/drier. If an A/C evaporator core leak is suspected, the A/C evaporator core must be leak tested before it is removed from the vehicle.
