Accumulator HVAC: Service and Repair
Suction Accumulator
NOTE: 6.4L diesel shown, 5.4L and 6.8L similar.
Removal and Installation
NOTE: Installation of a new suction accumulator is not required when repairing the A/C system, except when there is physical evidence of
contamination from a failed A/C compressor or damage to the suction accumulator. Damage to the suction accumulator includes leaks in the suction
accumulator, physical damage to the suction accumulator shell or desiccant, or moisture contamination. Moisture contamination results only from a
complete loss of refrigerant, and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than 1 hour. If even a
slight amount of position refrigerant pressure is present in the refrigerant system before repairs are carried out, the suction accumulator should not be
replaced.
1. Recover the refrigerant.
2. Disconnect the A/C cycling switch electrical connector.
3. Remove the RH fender splash shield.
4. Remove the suction accumulator outlet fitting nut and disconnect the fitting.
