The Four Seasons Accumulator (part number 33166) is a direct-fit replacement for 1987-1990 Buick, Chevrolet, GMC, and Oldsmobile vehicles with 3.3L, 2.8L, and 4.3L engines.
Features:
- Our accumulator / filter driers feature quality welds for a durable, leak-free design in addition to high-quality desiccant for appropriate absorption. For easy installation, necessary gaskets, o-rings and seal are included as well.
- The accumulator / filter drier acts as a filter by removing moisture and contaminants from the air conditioning system. Such contaminants cannot be removed by flushing, therefore replacing the accumulator / filter drier is essential.
- The absorption of moisture in the system is done through the use of a desiccant bag. A leaking or "open" system can cause the bag to become saturated within a few hours making the accumulator/filter drier ineffective.
- Replacement of the accumulator / filter drier is required to validate compressor warranty and must be replaced anytime the system is serviced.
