Keep moisture and debris out of your A/C refrigerant with the Four Seasons A/C Receiver Drier 33389, a steel filter drier that installs as a direct-fit replacement for the 1990-1993 Mercedes-Benz 300SL, 1990-1993 Mercedes-Benz 500SL, 1993 Mercedes-Benz 600SL, 1994-1997 Mercedes-Benz SL320, 1994-1995 Mercedes-Benz SL500, and 1994-1997 Mercedes-Benz SL600. See the Buyer's Guide tab for engine specifics. It acts as a filter, removing moisture and contaminants that can't be cleared by flushing the system.

  • Steel filter drier: built with quality welds for a durable, leak-free design.
  • High-quality desiccant: a desiccant bag absorbs moisture from the system for appropriate absorption.
  • Installation hardware included: the necessary gaskets, o-rings and seal are supplied for easy installation.
  • Backed by experience: produced in an ISO/TS16949 and ISO14001 certified facility, drawing on Four Seasons' mobile A/C know-how.

Because a leaking or open system can saturate the desiccant within a few hours and leave the drier ineffective, replacing it is essential whenever the system is serviced. Many compressor warranties require a new receiver drier be installed anytime the A/C is opened for service.
