Guidelines

Replace the suction accumulator/drier when:

^ The suction accumulator/drier is restricted plugged, or perforated.
^ The refrigerant system has been left open for more than four hours or completely discharged for 24 hours or more.
^ There is evidence of moisture in the system (for example, internal corrosion of metal lines or dark, thick refrigerant oil).
^ A component such as an A/C condenser core, evaporator, A/C compressor, or refrigerant line is replaced.
