Four Seasons A/C Receiver Drier P/N:33471
Keep moisture and debris out of your A/C system with the Four Seasons A/C Receiver Drier, MPN 83709. This steel filter drier drops in as a direct-fit replacement for the 1996-2000 Freightliner Century Class and the 2000-2002 Freightliner Columbia — see the Buyer's Guide tab for engine-level details.
The receiver drier acts as a filter, removing moisture and contaminants from the air conditioning system — contaminants that flushing alone cannot remove, which is why replacing the drier is essential whenever the system is serviced. Moisture absorption is handled by an internal desiccant bag; a leaking or "open" system can saturate that bag within a few hours and leave the drier ineffective, so a fresh unit is the right call after any repair.
Replacing the receiver drier is also required to validate compressor warranty and should be done anytime the A/C system is opened.
What does this receiver drier do?
It acts as a filter, removing moisture and contaminants from the A/C system that flushing cannot remove. An internal desiccant bag absorbs moisture to help protect the rest of the system.

It is a steel filter drier with quality welds for a durable, leak-free design, and a high-quality desiccant inside for moisture absorption.
