Q: How to replace the filter-drier element in a Toyota Prius air conditioning system?
A: To replace the A/C accumulator and condenser in an air conditioning system, follow these steps. Firstly, have the refrigerant discharged and recovered by an air conditioning technician. The A/C Condenser, located adjacent to the Radiator, needs to be removed from the vehicle. Use an Allen wrench to remove the large plug from the A/C accumulator and then use needle-nose pliers to extract the filter-drier element inside the A/C accumulator. When reinstalling, ensure the new filter-drier element is properly in place and lubricate the plug's O-ring with refrigerant oil. Once the replacement is complete, have the system evacuated, charged, and leak tested by the same shop that discharged the refrigerant. If the A/C accumulator or condenser was replaced, make sure to add new refrigeration oil to the system. It is essential to use refrigerant oil that is compatible with the refrigerant being used.
