Refrigerant: Service and Repair
Refrigerant System Filtering Following Air Conditioning (A/C) Compressor Installation
NOTICE: Motorcraft(R) Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft(R) Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. Refer to Refrigerant Oil Adding Refrigerant Oil Adding.
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.
All vehicles
1. Remove the receiver/drier cartridge.
2. NOTE: The refrigerant system must be filtered with the receiver/drier cartridge removed. 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.
3. Remove the condenser outlet fitting nut and disconnect the fitting.
- Discard the gasket seal.
4. 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 and the condenser outlet fitting.
5. NOTICE: Motorcraft(R) Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft(R) Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. Refer to Refrigerant Oil Adding Refrigerant Oil Adding.
Lubricate the refrigerant system with the correct amount of clean PAG oil (non-hybrid vehicles) or electric A/C compressor oil (hybrid vehicles). For additional information, refer to Refrigerant Oil Adding Refrigerant Oil Adding.
6. 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.
Non-hybrid vehicles
7. 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.
8. 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.
9. Stop the engine.
Hybrid vehicles
10. Start the vehicle and select A/C operation. Verify that the A/C is operating correctly.
11. Run the A/C system for one hour.
All vehicles
12. 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.
13. Remove the pancake filter, hoses and adapters from the vehicle.
14. Install a new gasket seal and connect the condenser outlet fitting.
15. Remove and discard the receiver/drier plug snap ring and the receiver/drier plug.
16. Install a new receiver/drier cartridge.
17. 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.
