Four Seasons A/C Accumulator P/N:33138

Keep moisture and debris out of your A/C system with the Four Seasons A/C Accumulator (MPN 33138). It installs as a direct-fit replacement for the 1994 Chevrolet Astro and 1994 GMC Safari — see the Buyer's Guide tab for engine-level fitment.

The accumulator / filter drier acts as a filter, removing moisture and contaminants from the air conditioning system that flushing cannot clear, which is why replacing it is essential whenever the system is serviced. Moisture absorption is handled by an internal desiccant bag; a leaking or "open" system can saturate that bag within a few hours, leaving the unit ineffective.

• Quality construction: Produced in an ISO/TS16949 & ISO14001 certified facility using state-of-the-art equipment and high-quality materials.
• Leak-free design: Quality welds create a durable, leak-free unit, paired with high-quality desiccant for appropriate moisture absorption.
• Ready to install: Necessary gaskets, o-rings and seal are included for easy installation.
• Backed by experience: Engineered and tested by Four Seasons, drawing on over 50 years of mobile A/C experience.

Replacement of the accumulator / filter drier is required to validate compressor warranty and should be done any time the system is opened or serviced.
