Help pull moisture and contaminants out of your truck's air conditioning with the Four Seasons A/C Receiver Drier / Filter Drier, part number 33359, a steel filter drier that works as the system's filter. It fits many Peterbilt trucks as a direct-fit replacement for the listed applications, among them the 1995-1996 Peterbilt 376, 1997 Peterbilt 372 and 2001-2002 Peterbilt 270. See the "Vehicles it fits" section for the full list and engine details.
Four Seasons describes this unit as a steel filter drier, and it is also cataloged as an A/C receiver drier, so you may find it under either name.
- Filters the system: Removes moisture and contaminants from the air conditioning system. Flushing cannot remove these contaminants, which is why Four Seasons calls replacing the drier essential.
- Desiccant bag: A high-quality desiccant bag absorbs moisture in the system. A leaking or open system can saturate the bag within a few hours and leave the drier ineffective.
- Welded steel construction: Quality welds are intended to give the drier a durable, leak-free design.
- Seals included: The necessary gaskets, o-rings and seal come with the drier for easier installation.
- Certified production: Produced in an ISO/TS16949 and ISO14001 certified facility and backed by more than 50 years of Four Seasons mobile A/C experience.
Four Seasons states that the drier must be replaced anytime the A/C system is serviced, and that replacing it is required to validate the compressor warranty. This part may need replacing if the system has been opened for repair or has leaked, because exposure to moisture can saturate the desiccant.
