Four Seasons A/C Accumulator P/N:83211

Description

Keep your air conditioning system dry and clean with the Four Seasons A/C Accumulator (P/N: 83211). It installs as a direct-fit replacement for the 2002-2004 GMC Sierra, 2002-2004 GMC Sierra 2500 HD, 2002-2004 GMC Sierra 3500, 2002-2004 Chevrolet Silverado 2500 HD, and 2002-2004 Chevrolet Silverado 3500 — see the Buyer's Guide tab for engine-level details.

The accumulator / filter drier acts as a filter, removing moisture and contaminants from the A/C system — debris that flushing alone cannot clear, which is why the unit is replaced whenever the system is opened.

Desiccant absorption: a desiccant bag draws in system moisture; a leaking or open system can saturate the bag within a few hours, making the accumulator ineffective.
Quality welds: built with quality welds for a durable, leak-free design plus high-quality desiccant for appropriate absorption.
Install hardware included: the necessary gaskets, o-rings and seal are included for easy installation.
Backed by experience: produced in an ISO/TS16949 & ISO14001 certified facility, drawing on over 50 years of mobile A/C experience.

Replacing the accumulator / filter drier is required to validate compressor warranty and should be done any time the system is serviced.

Frequently Asked Questions

What does this A/C accumulator do?

It acts as a filter, removing moisture and contaminants from the air conditioning system — debris that flushing alone cannot remove.

Which vehicles does P/N 83211 fit?

It fits the 2002-2004 GMC Sierra, Sierra 2500 HD, and Sierra 3500, plus the 2002-2004 Chevrolet Silverado 2500 HD and Silverado 3500. See the Buyer's Guide tab for engine details.

Are gaskets and seals included?

Yes. The necessary gaskets, o-rings and seal are included for easy installation.

Do I need to replace the accumulator when servicing the A/C?

Yes. It must be replaced any time the system is serviced, and replacement is required to validate compressor warranty.

Why can't the desiccant just be flushed clean?

Contaminants and saturated desiccant cannot be removed by flushing. A leaking or open system can saturate the bag within a few hours, so the unit is replaced instead.
