Help pull moisture and contaminants out of your truck's air conditioning with the Four Seasons A/C Receiver Drier, part number 33997, a steel filter drier that acts as the system's filter. It fits many Freightliner trucks, among them the 2010-2015 Freightliner Coronado, 2005-2011 Freightliner FLD120SD and 2002-2018 Freightliner M2 106, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.

The receiver drier removes moisture and contaminants from the A/C system. Flushing cannot remove these contaminants, which is why Four Seasons calls replacing the drier essential. A desiccant bag inside the unit absorbs the moisture. If the system is leaking or left open, that bag can become saturated within a few hours, leaving the drier ineffective.

  • Steel construction: a steel filter drier with quality welds, intended for a durable, leak-free build.
  • High-quality desiccant: provides appropriate absorption of moisture in the system.
  • Certified production: made in an ISO/TS16949 and ISO14001 certified facility with state-of-the-art equipment and high-quality materials.
  • Installation seals: Four Seasons includes the necessary gaskets, O-rings and seal with its accumulator/filter driers for easier installation.

Four Seasons draws on over 50 years of mobile A/C experience. The manufacturer requires a new drier to validate the compressor warranty, and says the drier must be replaced any time the A/C system is serviced.
