Product Details

The receiver drier is a key HVAC component that stores refrigerant, filters contaminants, and helps protect the A/C system from moisture-related damage. Four Seasons 33276 uses a steel housing with a 2.500 in. body diameter and 7.500 in. body length, plus male insert O-ring connections for straightforward replacement in systems built around this style of drier. The desiccant is not replaceable, and the unit is supplied without a fuse plug or pressure relief valve.

This part cross-references UAC RD6150C and Gates 27453 for the same application. It is a direct-fit style option for select vehicles including the 1985-1989 Isuzu I-Mark, 1985-1988 Chevrolet Spectrum, and 1986 Dodge Ram 50.

Common Problems This Part Can Address

• Moisture contamination in the A/C refrigerant circuit

Installation Notes

Replace the receiver drier any time the A/C system has been opened for major service, especially after compressor failure or refrigerant line repair.
