Receiver Dryer: Description and Operation

Fig 1 Filter/Drier Location:

FILTER/DRIER
The filter/drier is a receiver for reserve refrigerant. It also has a desiccant bag and a filter. This is used to absorb moisture and filter the refrigerant as it passes through the filter/drier.

The filter/drier is located forward of the coolant bottle. The A/C refrigerant must be removed from the system before removing the filter/drier. Always use a refrigerant recovery machine.

Replace the filter/drier if an A/C system is left open for an extended period of time.
