Q: How to remove and install a receiver/drier for automotive air conditioning on Toyota Celica?
A: Discharge the refrigerant at a dealer or repair facility. The A/C accumulator is in the left front corner of the engine compartment. Detach the refrigerant lines from it, cap them, and remove the A/C accumulator. Cap the open fittings to avoid dirt and moisture. Install new O-rings on the lines, lubricate with refrigerant oil, and reinstall the A/C accumulator. Ensure correct inlet and outlet connections. If a new A/C accumulator is installed, add 20 cc of refrigerant oil. Have the system evacuated, charged, and leak tested by the discharging shop.
