Accumulator HVAC: Service and Repair

-
SUCTION ACCUMULATOR - 2.5L AND 3.0L REMOVAL/INSTALLATION










NOTE:The receiver/drier fitting studs can be removed and installed separately from the receiver/drier and are available as service parts. If only the fitting studs are damaged, it is not necessary to install a new receiver/drier.
NOTE:Installation of a new receiver/drier is not required when repairing the air conditioning system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks, physical damage to the receiver/drier 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 one hour. If even a slight amount of positive refrigerant pressure is present in the refrigerant system before repairs are carried out, a new receiver/drier should not be installed.
