Four Seasons A/C Accumulator P/N:83274
Keep moisture and contaminants out of your A/C system with the Four Seasons A/C Accumulator, MPN 33170. It installs as a direct-fit replacement for the 1975 Pontiac Astre, the 1980-1984 Chevrolet G10, G20, and G30, and the 1980-1984 GMC G1500, G2500, and G3500 — see the Buyer's Guide tab for engine-level fitment.
The accumulator / filter drier acts as a filter, removing moisture and contaminants from the air conditioning system — debris that flushing alone cannot clear, which is why replacing the unit during service is essential.
A leaking or "open" system can saturate the desiccant bag within a few hours, so a saturated or contaminated accumulator should be replaced anytime the A/C system is opened or serviced. Many compressor warranties also require replacing the accumulator / filter drier whenever the system is serviced.
