Keep your A/C system dry and clean with the Four Seasons Universal Tank Accumulator, MPN 33204. It installs as a direct-fit replacement across a wide range of GM applications, including the 1979-1980 Buick Skyhawk, 1980-1981 Buick Skylark, 1973-1984 Buick Chevy Blazer, 1973-1984 Chevrolet C10 Suburban, 1975-1984 Chevrolet C10, 1975-1984 Chevrolet K5 Blazer, 1978-1980 Chevrolet Monza, 1973-1984 GMC Jimmy, 1980-1981 Oldsmobile Omega, 1978-1980 Oldsmobile Starfire, 1980-1981 Pontiac Phoenix and 1978-1980 Pontiac Sunbird — see the Buyer's Guide tab for the full list of 79 applications.

The accumulator/filter drier works to remove moisture and contaminants that flushing cannot clear, which is why replacing it is essential whenever the system is opened.

  • Moisture & contaminant control: a desiccant bag absorbs moisture while the unit filters contaminants from the refrigerant circuit.
  • Leak-resistant build: quality welds are used for a durable, leak-free design, with high-quality desiccant for appropriate absorption.
  • Installation hardware included: the necessary gaskets, o-rings and seal are supplied for the job.
  • Service note: a leaking or open system can saturate the desiccant within hours, and replacement is required to validate the compressor warranty.

Frequently Asked Questions

What does this accumulator do?

It acts as a filter drier, using a desiccant bag to absorb moisture and remove contaminants from the A/C system — debris that flushing alone cannot clear.

Are gaskets and seals included?

Yes. Four Seasons includes the necessary gaskets, o-rings and seal for installation.

When should the accumulator be replaced?

It should be replaced any time the A/C system is opened or serviced, and replacement is required to validate the compressor warranty.

Will it fit my vehicle?

It fits 79 GM applications spanning 1973-1984 Buick, Chevrolet, GMC, Oldsmobile and Pontiac models. Check the Buyer's Guide tab to confirm your exact year, make and model.

Why can a saturated desiccant bag be a problem?

A leaking or open system can saturate the desiccant bag within a few hours, making the accumulator/filter drier ineffective at absorbing moisture.
