Help clear moisture and contaminants from your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier, part number 33283. It is a steel filter drier built around a moisture-absorbing desiccant bag. It fits many Ford and Mercury vehicles, among them the 1975-1979 Ford F-150 and 1972-1979 Ford F-250, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
This unit is listed under both names, A/C receiver drier and filter drier, and it works as a filter for the A/C system by removing moisture and contaminants. Four Seasons notes that these contaminants cannot be removed by flushing, so replacing the drier is an essential step in A/C service.
- Steel construction: Quality welds give it a durable, leak-free design.
- High-quality desiccant: An internal desiccant bag absorbs moisture in the system.
- Certified production: It is 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 unit for easier installation.
When to replace: A leaking or open system can saturate the desiccant bag within a few hours, which leaves the drier ineffective. Four Seasons requires a new drier to validate the compressor warranty and calls for replacing it anytime the system is serviced. The brand has more than 50 years of experience with mobile A/C.
