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.
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.
