Four Seasons A/C Accumulator P/N:83274
Keep your air conditioning system clean and dry with the Four Seasons A/C Accumulator, MPN 83232. Backed by more than 50 years of mobile A/C experience, it drops in as a direct-fit replacement across a wide GM truck and SUV lineup — including the 2011-2013 Cadillac Escalade EXT, 2010-2013 Chevrolet Silverado 1500, 2010-2014 Chevrolet Tahoe, 2010-2014 GMC Sierra, and 2010-2014 GMC Yukon. With 32 applications covered, see the Buyer's Guide tab for the full year-make-model list.
The accumulator / filter drier works to remove moisture and contaminants from the refrigerant circuit — debris that flushing alone cannot clear — which is why replacing it during service is essential.
Replacing the accumulator / filter drier is required to validate compressor warranty and should be done anytime the system is opened, since a leaking or open system can saturate the desiccant within hours and leave the unit ineffective.
