Description & Operation: Receiver/Drier

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

The receiver/drier is located in the engine compartment near the dash panel on the passenger side of the vehicle. The receiver/drier incorporates a sight glass for visual diagnosis of the refrigerant system.

High-pressure liquid refrigerant from the condenser flows into the receiver/drier. A drying agent, called a desiccant, is used to remove any traces of moisture from the refrigerant system. The receiver/drier also performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. In addition, during periods of high demand air conditioner operation, the receiver/drier acts as a reservoir to store surplus refrigerant. The A/C refrigerant must be removed from the system before removing the receiver/drier using a refrigerant recovery machine. Replace the receiver/drier if an A/C system is left open for an extended period of time. The receiver/drier cannot be repaired and, if faulty, must be replaced.
