Backed by over 50 years of mobile A/C experience, Four Seasons builds its accumulator/filter driers in an ISO/TS16949 & ISO14001 certified facility.
What does this A/C accumulator do?
It acts as a filter, removing moisture and contaminants from the air conditioning system using a desiccant bag that absorbs moisture the system's refrigerant carries.
Does it come with installation hardware?
Yes. According to Four Seasons, the necessary gaskets, o-rings and seal are included for installation.
Which vehicles does part number 33166 fit?
It fits GM applications such as the 1989-1990 Buick Century/Celebrity, 1987-1989 Chevrolet Astro and GMC Safari, and 1989-1990 Pontiac 6000. Check the Buyer's Guide tab for the full list.
Why should the accumulator be replaced when servicing the A/C?
A leaking or open system can saturate the desiccant bag within a few hours, making the unit ineffective, so it is replaced anytime the system is serviced.
Can flushing remove the contaminants instead of replacing this part?
No. Four Seasons notes that such contaminants cannot be removed by flushing, so replacing the accumulator/filter drier is essential.
