Help keep moisture and contaminants out of your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier, part number 33318, a steel filter drier built for replacement service. It fits many vehicles, among them the 1976-1981 Honda Accord, 1975-1979 Honda Civic and 1970-1979 Toyota Corolla, and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.

Four Seasons calls this part a filter drier, and it is cataloged as an A/C receiver drier. Both names refer to this same unit. It acts as a filter, removing moisture and contaminants from the A/C system. Flushing cannot remove these contaminants, so Four Seasons considers replacing the drier essential.

  • Welded steel body: quality welds are designed to give a durable, leak-free build.
  • Desiccant bag: high-quality desiccant absorbs moisture inside the system. A leaking or open system can saturate the bag within a few hours, which leaves the drier ineffective.
  • Seals included: the gaskets, o-rings and seal needed for installation come with the drier.
  • Certified production: the drier is produced in an ISO/TS16949 and ISO14001 certified facility, and Four Seasons brings over 50 years of mobile A/C experience.

When to replace: Four Seasons states that the drier must be replaced any time the system is serviced. Replacing it is also required to validate the compressor warranty. Signs it may be due include a system that has been opened or left open to the air, a leak repair, or a compressor replacement.
