Description

Keep the refrigerant clean and dry in your heavy-duty A/C system with the Four Seasons A/C Receiver Drier (Steel Filter Drier), MPN 33531. It installs as a direct-fit replacement for the 1985-1989 Mack MS200P, MS250P, MS300P and MS300T Mid-Liner, plus the 1981-1993 Peterbilt 362 and 1989-1993 Peterbilt 372 — see the "Vehicles it fits" section for engine-level details.

The receiver drier acts as a filter, using an internal desiccant to absorb moisture and trap contaminants that circulate through the air conditioning system — debris that cannot be removed by flushing, which is why the drier is replaced whenever the system is opened or serviced.

Steel construction: a steel filter drier built with quality welds for a durable, leak-free design.
Desiccant filtration: high-quality desiccant absorbs moisture while the unit filters out contaminants from the refrigerant.
Installation hardware: the necessary gaskets, o-rings and seal are included for the installation.
Backed by experience: produced in an ISO/TS16949 & ISO14001 certified facility and backed by over 50 years of Four Seasons mobile A/C experience.

Signs the original drier may need replacing include a saturated desiccant from a leaking or open system and reduced A/C performance after service. Replacing the drier is also required to validate many compressor warranties.
