Description

Keep the A/C system dry and clean with the Four Seasons A/C Accumulator, MPN 33129. It installs as a direct-fit replacement for the listed applications, including the 1992-1993 Buick LeSabre, 1991-1993 Buick Park Avenue, 1991-1993 Cadillac DeVille / Coupe DeVille / Sedan DeVille, 1991-1992 Cadillac Fleetwood, 1992-1993 Pontiac Bonneville, 1992-1993 Oldsmobile 88, and 1991-1993 Oldsmobile 98 — see the Buyer's Guide tab for the full list. Mounted on the low-pressure side, the accumulator stores refrigerant, separates liquid from vapor, and uses its desiccant to pull moisture and contaminants out of the system.

Filters and dries: Acts as a filter that removes moisture and contaminants the way flushing cannot, which is why replacing the accumulator/filter drier is essential when the system is opened.
Desiccant absorption: Draws moisture from the system through a desiccant bag; a leaking or "open" system can saturate the bag within hours and leave it ineffective.
Leak-resistant build: Quality welds support a durable, leak-free design paired with high-quality desiccant for appropriate absorption.
Ready to install: Includes the necessary gaskets, o-rings, and seal for the job.

Four Seasons recommends replacing the accumulator/filter drier anytime the system is serviced, and notes it may be required to validate a compressor warranty.

Frequently Asked Questions

What does this A/C accumulator do?

It stores refrigerant on the low-pressure side, separates liquid from vapor, and uses a desiccant to remove moisture and contaminants that flushing cannot eliminate.

Which vehicles does the Four Seasons 33129 fit?

It is a direct-fit replacement for applications such as the 1992-1993 Buick LeSabre, 1991-1993 Cadillac DeVille, and 1991-1993 Oldsmobile 98. Check the Buyer's Guide tab for the complete list.

Does it come with seals?

Yes. The necessary gaskets, o-rings, and seal are included for installation.

When should the accumulator be replaced?

Four Seasons advises replacing the accumulator/filter drier anytime the A/C system is serviced or opened, since the desiccant can saturate quickly once exposed.

Why replace it instead of flushing the system?

Moisture and contaminants trapped in the accumulator/filter drier cannot be removed by flushing, so replacing the unit is essential when servicing the system.
