Scion 88474-17010 A/C Receiver Drier

To remove the A/C accumulator, the refrigerant must be discharged and recovered from the system. Located on the passenger's side of the vehicle, at the end of the condenser, the A/C accumulator can be removed by using an Allen wrench to remove the large plug at the bottom. The filter-drier element inside can then be extracted with needle-nose pliers. For installation, follow the reverse order, ensuring the plug's O-ring is lubricated with refrigerant oil. The system must be evacuated, charged, and leak tested. If the A/C accumulator or A/C Condenser was replaced, new refrigeration oil compatible with R-134a refrigerant must be added.
