Four Seasons A/C Accumulator P/N:33191

Description

Keep your air conditioning system clean and dry with the Four Seasons A/C Accumulator, MPN 33191. It installs as a direct-fit replacement for the 1987 Buick Skyhawk, 1987 Buick Olds Firenza, 1987 Oldsmobile Firenza, 1987 Pontiac Sunbird, and 1987 Pontiac Sunbird / J2000 Sunbird — see the Buyer's Guide tab for engine specifics. The accumulator / filter drier works as the system's filter, pulling moisture and contaminants out of the refrigerant circuit — debris that flushing alone can't remove, which is why replacing this unit during service is important.

Desiccant drying: Uses a desiccant bag to absorb moisture; a leaking or open system can saturate that bag within hours, so timely replacement matters.
Leak-resistant build: Quality welds are used for a durable, leak-free design.
Installation hardware: Necessary gaskets, o-rings, and seal are included for easier installation.
Service best practice: Replacing the accumulator / filter drier is required to validate the compressor warranty and should be done anytime the system is opened for service.

Backed by Four Seasons' decades of mobile A/C experience and produced in an ISO/TS16949 & ISO14001 certified facility, this unit is built for long-lasting performance.

Frequently Asked Questions

What does this A/C accumulator do?

It acts as a filter and moisture trap, removing moisture and contaminants from the air conditioning refrigerant circuit using an internal desiccant bag.

Which vehicles does MPN 33191 fit?

It fits the 1987 Buick Skyhawk, 1987 Buick Olds Firenza, 1987 Oldsmobile Firenza, 1987 Pontiac Sunbird, and 1987 Pontiac Sunbird / J2000 Sunbird. Check the Buyer's Guide tab for engine details.

Are gaskets and o-rings included?

Yes. The necessary gaskets, o-rings, and seal are included to make installation easier.

Do I need to replace the accumulator when servicing the A/C?

Yes. Four Seasons states it must be replaced anytime the system is serviced, and replacement is required to validate the compressor warranty.

Why can't I just flush the old accumulator?

Flushing can't remove the moisture and contaminants the desiccant captures, and a saturated desiccant bag becomes ineffective, so the unit should be replaced instead.
