Four Seasons A/C Accumulator P/N:33218
$32.99

Keep clean, dry refrigerant circulating through your A/C with the Four Seasons A/C Accumulator 33218. It's a direct-fit replacement for the 1996-2005 Chevrolet Astro and 1996-2005 GMC Safari — see the Buyer's Guide tab for engine-level fitment.

  • Filters and dries the system: the accumulator / filter drier removes moisture and contaminants from the refrigerant that flushing alone can't clear, which is why replacing it during service is essential.
  • Desiccant absorption: a desiccant bag absorbs moisture from the system; a leaking or "open" system can saturate the bag within a few hours and leave the accumulator ineffective.
  • Durable, leak-free build: quality welds and high-quality desiccant are used for reliable moisture absorption and a leak-resistant design.
  • Installation hardware: the necessary gaskets, o-rings and seal are included for easier installation.

Backed by Four Seasons' decades of mobile A/C experience, this unit is produced in an ISO/TS16949 and ISO14001 certified facility. Replacing the accumulator / filter drier is required to validate compressor warranty and should be done any time the A/C system is opened or serviced.
