Town & Country V6-3.3L VIN R (2003)
Receiver Dryer: Description and Operation
The filter-drier is mounted in a bracket secured to the right front strut tower in the engine compartment. The filter-drier is connected between the front
and rear sections of the liquid line between the condenser outlet and the evaporator inlet. The filter- drier cannot be repaired. If the filter-drier is faulty or
damaged, or if the refrigerant system has been contaminated or left open to the atmosphere for an indeterminable period, it must be replaced.
The filter-drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. A desiccant bag is
mounted inside the filter-drier canister to absorb any moisture which may have entered and become trapped within the refrigerant system. In addition,
during periods of high demand air conditioner operation, the filter-drier acts as a reservoir to store surplus refrigerant. Refrigerant enters the filter-drier
as a high-pressure, low temperature liquid.
