Four Seasons A/C Receiver Drier P/N:33374

Keep moisture and debris out of the air conditioning loop with the Four Seasons A/C Receiver Drier 33374, a steel filter drier that drops in as a replacement for the 1986-1991 Volkswagen Vanagon (see the Buyer's Guide tab for engine-level fitment). It filters the refrigerant, trapping moisture and contaminants that circulate through the system — debris that can't be removed by flushing, which is why the drier is replaced whenever the system is opened for service.

• Steel filter drier: built with quality welds for a durable, leak-free design.
• Moisture control: uses a desiccant to absorb moisture from the refrigerant for appropriate absorption.
• Filters contaminants: removes moisture and contaminants the system can't clear by flushing.
• Installation hardware: the necessary gaskets, o-rings and seal are included.

A leaking or "open" system can saturate the desiccant bag within a few hours, leaving the drier ineffective — so replace it any time the A/C is serviced. Replacing the drier is also required to validate compressor warranty. Backed by Four Seasons' mobile A/C experience and produced in an ISO/TS16949 and ISO14001 certified facility for consistent product integrity. If a saturated or contaminated drier is the cause of poor A/C performance, this unit replaces it.
