Description

Keep the refrigerant in your A/C system clean and dry with the Four Seasons A/C Receiver Drier / Filter Drier 33991, a steel filter drier that drops in as a direct-fit replacement for the 2016-2017 Kenworth T370, the 2010-2012 Peterbilt 325 and 330, and the 2010 Peterbilt 335 and 340. See the "Vehicles it fits" section for engine-level fitment details.

Steel construction with quality welds: built for a durable, leak-free design.
High-quality desiccant: a desiccant bag absorbs moisture from the refrigerant for appropriate absorption.
Installation hardware included: the necessary gaskets, o-rings and seal are supplied for easier installation.

The filter drier acts as a filter, removing moisture and contaminants from the air conditioning system — debris that cannot be cleared by flushing, which is why replacing the drier is part of servicing the system. Because a leaking or open system can saturate the desiccant bag within hours, the drier should be replaced any time the A/C system is opened for service. Four Seasons also notes that replacing the drier is required to validate the compressor warranty.

It acts as a filter, removing moisture and contaminants from the A/C refrigerant using a desiccant bag. These contaminants can't be cleared by flushing, so the drier handles them.

Are any installation parts included?

Yes. Four Seasons includes the necessary gaskets, o-rings and seal to make installation easier.

When should I replace the drier?

Replace it any time the A/C system is opened for service. A leaking or open system can saturate the desiccant bag within a few hours, making the drier ineffective.
