Keep the refrigerant in your A/C system clean and dry with the Four Seasons A/C Receiver Drier 33986, a steel filter drier that installs as a direct-fit replacement for the 1993-1994 Chevrolet P30, P60 and P6000, plus the GMC P2500 (1985-1989), P3500 (1985-1995), P4500 (1985-1990), P6000 (1993-1994) and P6500 (1992-1995). See the "Vehicles it fits" section for full engine-level fitment.
The receiver drier acts as a filter, removing moisture and contaminants that flushing cannot clear from the air conditioning system. Its internal desiccant absorbs moisture; once a system is opened or leaking, that desiccant can saturate within a few hours, so replacing the drier whenever the system is serviced helps keep the refrigerant clean and dry.
- Steel filter drier: steel construction for a durable unit.
- Quality welds: built for a durable, leak-free design.
- High-quality desiccant: intended to absorb moisture for appropriate protection.
- Install hardware included: the necessary gaskets, o-rings and seal come in the box.
Replacement is typically required to validate the compressor warranty and should be performed any time the A/C system is opened for service. Backed by decades of Four Seasons mobile A/C experience.
