Backed by over 50 years of mobile A/C experience from Four Seasons, this accumulator/filter drier should be replaced any time the system is serviced.
What does the A/C accumulator do?
It acts as a filter, removing moisture and contaminants from the air conditioning system using a desiccant bag. These contaminants cannot be removed by flushing, so replacing the unit is essential.
Does this unit include installation hardware?
Yes. The necessary gaskets, o-rings and seal are included for easier installation.
Which vehicles does MPN 83291 fit?
It fits 2003-2007 GMC Sierra and Sierra 2500 HD, 2003-2006 Sierra 3500, 2003-2007 Chevrolet Silverado 2500 HD, 2003-2006 Silverado 3500, and 2007 Classic/HD variants. See the Buyer's Guide tab.
When should the accumulator be replaced?
Four Seasons advises replacing it any time the A/C system is serviced. A leaking or open system can saturate the desiccant bag within hours, making the unit ineffective.
Why can't I just flush the system instead?
Flushing cannot remove the moisture and contaminants that collect in the accumulator/filter drier, so replacing the unit is necessary when servicing the system.
