A/C Receiver Drier for 2011-2012 Peterbilt 587 & More - Four Seasons 83701

Help keep your truck's air conditioning clean and dry with the Four Seasons A/C Receiver Drier / Filter Drier, part number 83701, a steel filter drier that removes moisture and contaminants from the refrigerant circuit. It fits many Kenworth and Peterbilt trucks, among them the 2010-2011 Kenworth T170, 1996-1999 Kenworth T400 and 1996-2008 Kenworth W900. See the "Vehicles it fits" section for the full list. It is a direct-fit replacement for the listed applications and is listed under both the receiver drier and filter drier names.

• Filters the system: The drier works as a filter, removing moisture and contaminants from the A/C system. Flushing alone cannot remove these contaminants.
• Desiccant bag: A bag of high-quality desiccant absorbs moisture in the system. A leaking or open system can saturate the bag within a few hours, which leaves the drier ineffective.
• Steel construction: This steel filter drier is built with quality welds for a durable, leak-free design.
• Seals included: The gaskets, O-rings and seal needed for installation come in the box.
• Certified production: It is produced in an ISO/TS16949 and ISO14001 certified facility and backed by Four Seasons' more than 50 years of mobile A/C experience.

Four Seasons states that replacing the filter drier is required to validate compressor warranty. It also states the drier must be replaced any time the system is serviced. Signs this part may need replacing include an A/C system that has been opened for repair, a system found leaking, or moisture in the system.
