A/C Accumulator for 1986-1993 Ford Aerostar - Four Seasons 33174

Keep your air conditioning clean and dry with the Four Seasons A/C Accumulator 33174. It installs as a direct-fit replacement for the 1986-1993 Ford Aerostar (see the Buyer's Guide tab for engine-level details). Positioned on the low-pressure side of the A/C system, the accumulator stores refrigerant and uses an internal desiccant to absorb moisture while filtering out contaminants that can't be cleared by flushing — which is why it should be replaced whenever the system is opened or serviced.

• Moisture & contaminant control: An internal desiccant bag absorbs moisture and helps filter contaminants from the refrigerant circulating through the system.
• Leak-free build: Quality welds are used for a durable, leak-resistant design.
• Installation hardware included: The necessary gaskets, o-rings and seal are supplied for the install.
• Quality manufacturing: Produced in an ISO/TS16949 & ISO14001 certified facility using state-of-the-art equipment and high-quality materials.

A leaking or open system can saturate the desiccant within hours, leaving the accumulator ineffective, so a fresh unit is recommended any time the A/C is serviced. Replacing the accumulator/filter drier is also required to validate many compressor warranties. Backed by Four Seasons' decades of mobile A/C experience.
