Receiver Drier
WARNING: This page is about a different car, the 2015 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
It is not necessary to install a new receiver/drier when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present in the system before repairs are carried out, the receiver/drier should not be replaced.
The receiver/drier stores high-pressure liquid and the desiccant bag mounted inside the receiver/drier removes any retained moisture from the refrigerant.
For 3.7L Ti-VCT engine equipped vehicles, the receiver/drier is integral to the A/C condenser. The receiver/drier desiccant bag is a separate component and can be removed and installed with the A/C condenser in the vehicle.
For 2.0L/3.5L GTDI engine equipped vehicles, the receiver/drier is mounted between the condenser outlet and the TXV manifold and tube assembly.
