The A/C receiver/drier (1) stores unnecessary refrigerant, filters the refrigerant, helps remove moisture from the refrigerant and retains any refrigerant vapor that may leave the A/C condenser (2) until it becomes a liquid. The A/C receiver/drier is installed on the high-side of the A/C system and is connected directly to the right end of the A/C condenser by a bolt (3). The A/C receiver/drier can be serviced separately from the A/C condenser.
