Description

Keep your air conditioning system clean and dry with the Four Seasons A/C Accumulator, MPN 33352. It installs as a direct-fit replacement across a wide range of Kenworth and Peterbilt trucks, including the 1998-2008 Kenworth C500, 1998-2005 Kenworth T300, 1998-2008 Kenworth W900, 1998-2008 Peterbilt 357, 1998-2007 Peterbilt 379, and 2006-2010 Peterbilt 386 — see the Buyer's Guide tab for the full list of 40 applications and their engine details.

The accumulator / filter drier acts as a filter, removing moisture and contaminants from the A/C system that flushing alone cannot clear, which is why replacing it is essential during service.

Desiccant drying: A desiccant bag absorbs moisture from the system; a leaking or open system can saturate the bag within a few hours, making the unit ineffective.
Durable build: Quality welds provide a leak-free design, paired with high-quality desiccant for appropriate absorption.
Ready to install: The necessary gaskets, o-rings and seal are included for the job.
Backed by experience: Built in an ISO/TS16949 & ISO14001 certified facility, drawing on over 50 years of mobile A/C experience.

Replacement is required to validate compressor warranty and should be done anytime the system is opened or 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 that cannot be cleared by flushing, helping protect the rest of the A/C components.

Are gaskets and o-rings included?

Yes. Four Seasons includes the necessary gaskets, o-rings and seal for installation.

Why should I replace the accumulator when servicing the A/C?

Replacement is required to validate compressor warranty and must be done anytime the system is serviced, since contaminants and saturated desiccant cannot be flushed out.

How does it remove moisture?

Moisture is absorbed by a desiccant bag inside the unit. A leaking or open system can saturate the bag within a few hours, making the accumulator ineffective.

Will this fit my truck?

It is a direct-fit replacement for many Kenworth and Peterbilt models from 1998-2010. Check the Buyer's Guide tab to confirm the year, make and model for your vehicle.
