Four Seasons A/C Accumulator P/N:33133
Keep your air conditioning system dry and clean with the Four Seasons A/C Accumulator (MPN 33132). It installs as a direct-fit replacement for the listed 1992-1993 Chevrolet Caprice, 1992-1993 Chevrolet Commercial Chassis, 1993 Cadillac Fleetwood, and 1992 Oldsmobile Custom Cruiser — see the Buyer's Guide tab for the full application list. Mounted on the low-pressure side, the accumulator/filter drier stores refrigerant and uses an internal desiccant to pull moisture and contaminants out of the system — debris that flushing alone cannot remove, which is why the unit is replaced whenever the system is opened or serviced.
Backed by Four Seasons' long history in mobile A/C. Replacing the accumulator/filter drier is also required to validate a compressor warranty and should be done any time the system is serviced.
