A leaking or open system can saturate the desiccant bag within a few hours, so replace the accumulator whenever the A/C system is serviced. Doing so is also required to validate the compressor warranty. Backed by over 50 years of mobile A/C experience from Four Seasons.
What does an A/C accumulator do?
It acts as a filter, removing moisture and contaminants from the air conditioning system using an internal desiccant bag — contaminants that flushing cannot remove.
Which vehicles does MPN 83238 fit?
It fits the Chevrolet Express 1500/2500/3500/4500, Express Cargo and Pasajeros, plus the GMC Savana 1500/2500/3500/4500. Check the Buyer's Guide tab for exact years and engines.
Are gaskets and o-rings included?
Yes. The necessary gaskets, o-rings, and seal are included with this accumulator for the installation.
When should I replace the accumulator?
Replace it anytime the A/C system is serviced. A leaking or open system can saturate the desiccant bag within a few hours, making the unit ineffective.
Does replacing it affect the compressor warranty?
Replacement of the accumulator/filter drier is required to validate the compressor warranty, so it should be replaced when the system is serviced.
