Refrigerant System Filtering Following Air Conditioning (A/C) Compressor Installation









NOTICE: On vehicles being serviced for an internal compressor or desiccant failure, a new Thermostatic Expansion Valve (TXV) and any hoses containing mufflers must be installed prior to filtering the Air Conditioning (A/C) system. Internal plumbing of these devices makes it impossible to correctly remove any foreign material/debris. These components are typically discarded after A/C system contamination. Hoses without mufflers can normally be reused unless they are clogged with foreign material. The F8VZ-19E773-AB filter is intended for use on one vehicle only.

1. Remove the condenser core.

2. Remove the plastic receiver/drier cap.

3. Remove the receiver/drier plug.

1. Push the receiver/drier plug upwards and remove the snap ring.

2. Install an M5 bolt in the center of the receiver/drier plug and remove the plug.





4. Using a suitable tool, grasp the receiver/drier cartridge grab handle and remove the receiver/drier cartridge.





5. NOTE: Do not install a new receiver/drier cartridge at this time.

With the receiver/drier cartridge removed, reinstall the receiver/drier plug and snap ring into the condenser core.

6. NOTE: Do not evacuate or charge the refrigerant system at this time.

Install the condenser core back into the vehicle and completely reassemble the vehicle except for the condenser outlet fitting.

7. NOTICE: The flexible extension adapters included in the A/C Flush Adapter Kit (219-00074) are designed for low-pressure flushing and are not designed for use with a charged refrigerant system. Do not make the condenser fitting connections using the flexible extension adapters or damage to the adapters and loss of refrigerant will occur.

NOTE: Use flexible refrigerant hose of 17,238 kPa (2,500 psi) burst rating.

Using the correct adapters and service hoses, install the pancake filter between the condenser outlet and the condenser outlet fitting.

8. Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to Refrigerant Oil Adding Refrigerant Oil Adding.

9. Evacuate and charge the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging Air Conditioning (A/C) System Recovery, Evacuation and Charging.

10. Provide adequate airflow to the front of the vehicle (with a fan, if necessary). Start the engine and allow it to idle briefly. Select A/C operation and set the blower speed to HI. Verify that the A/C is operating correctly.

11. Gradually bring the engine up to 1,200 rpm by running it at lower rpms for short periods (first at 800 rpm, then at 1,000 rpm). Set the engine at 1,200 rpm and run it for one hour with the A/C system operating.

12. Stop the engine.

13. Recover the refrigerant. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging Air Conditioning (A/C) System Recovery, Evacuation and Charging.

14. Remove the pancake filter, hoses and adapter from the vehicle.

15. Remove the condenser core.

16. Remove and discard the receiver/drier plug snap ring and the receiver/drier plug.

17. Install a new receiver/drier cartridge.

18. NOTE: The vehicle should be fully assembled at the completion of this step.

Install the condenser core.

19. Evacuate, leak test and charge the refrigerant system. For additional information refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging Air Conditioning (A/C) System Recovery, Evacuation and Charging.
