Description

Keep your air conditioning system clean and dry with the Four Seasons A/C Accumulator 33178. It installs as a direct-fit replacement across a wide range of 1980s–early-'90s GM cars and the Audi V8 Quattro, including the 1990-1993 Audi V8 Quattro, 1982-1990 Buick Century, 1988-1989 Buick Reatta, 1986-1989 Buick Riviera, 1982-1990 Chevrolet Celebrity, 1982-1990 Oldsmobile Cutlass Ciera, 1982-1991 Pontiac 6000, and many more — see the Buyer's Guide tab for the full list of applications and engines.

Filters and dries the refrigerant: the accumulator/filter drier removes moisture and contaminants from the A/C system, protecting components from debris that flushing cannot clear.
Desiccant-based moisture control: a desiccant bag absorbs moisture in the system; a leaking or open system can saturate the bag within hours, so replacement is essential once the system has been open.
Durable, leak-resistant build: quality welds are used for a leak-free design, and high-quality desiccant supports appropriate absorption.
Installation hardware included: the necessary gaskets, o-rings and seal are supplied for easier installation.

Four Seasons notes that replacing the accumulator/filter drier is required to validate the compressor warranty and should be done anytime the system is serviced. Backed by over 50 years of mobile A/C experience.

Frequently Asked Questions

What does this A/C accumulator do?

It acts as a filter drier, using a desiccant bag to remove moisture and contaminants from the air conditioning system that cannot be cleared by flushing.

Are seals included with the accumulator?

Yes. Four Seasons includes the necessary gaskets, o-rings and seal to make installation easier.

When should the accumulator be replaced?

Four Seasons states it should be replaced anytime the A/C system is serviced or opened, and replacement is required to validate the compressor warranty.

Why replace it after the system has been open?

A leaking or open system can saturate the desiccant bag within a few hours, making the accumulator/filter drier ineffective, so a fresh unit is recommended.

Will this fit my vehicle?

It is a direct-fit replacement for many 1982-1993 GM models and the Audi V8 Quattro. Check the Buyer's Guide tab to confirm the exact year, make and model.
