Help keep moisture and contaminants out of your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier, part number 33317, a steel filter drier built with a desiccant that absorbs moisture as refrigerant passes through. It is a direct-fit replacement for many vehicles, among them the 1966-1970 Dodge Charger, 1964-1970 Chrysler 300 and 1969-1970 Dodge A100 Truck. See the "Vehicles it fits" section for the full list and engine details.
- Welded steel body: quality welds are designed to give the drier a durable, leak-free build.
- High-quality desiccant: a desiccant bag inside absorbs moisture circulating in the A/C system.
- Certified production: made in an ISO/TS16949 and ISO14001 certified facility using state-of-the-art equipment and high-quality materials.
- Installation seals included: the necessary gaskets, O-rings and seal come with the drier.
The drier works as the system's filter, taking out moisture and contaminants that flushing cannot remove. If the system is leaking or left open, the desiccant bag can become saturated within a few hours. Once saturated, the drier can no longer do its job. Four Seasons states that the drier must be replaced any time the system is serviced, and that replacing it is required to validate the compressor warranty.
Four Seasons brings more than 50 years of mobile A/C experience to its accumulators and filter driers. This part is listed under both names, A/C Receiver Drier and Filter Drier.
