Help clear moisture and contaminants from your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier, part number 33257. This steel filter drier filters the refrigerant as it passes through and absorbs moisture in its desiccant. It fits many vehicles, among them the 1987-1988 Dodge Dakota, 1987-1988 Dodge Grand Caravan and 1984-1988 Chrysler Town & Country, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
This part is listed under both names: A/C receiver drier and filter drier.
- Moisture and contaminant removal: Works as a filter for the A/C system. A desiccant bag inside absorbs moisture from the system.
- Welded steel drier: Quality welds are intended to give a durable, leak-free design. It is paired with high-quality desiccant for appropriate absorption.
- Installation seals included: The necessary gaskets, O-rings and seal come with the drier for easier installation.
- Certified production: Produced in an ISO/TS16949 and ISO14001 certified facility and backed by more than 50 years of Four Seasons mobile A/C experience.
Why replace it during service: Contaminants held in the drier can't be cleared by flushing the system. A leaking or open system can saturate the desiccant bag within a few hours, which leaves the drier ineffective. Four Seasons calls for replacing the drier any time the A/C system is serviced, and replacement is required to validate its compressor warranty.
Consider replacing the receiver drier when the A/C system has been opened for repair or left open to the air, when the compressor is replaced, or when moisture contamination is found during service.
