Refrigerant System Charging Using a R-134a Refrigerant Management Machine
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Ford Motor Company recommends use of a R-134a Refrigerant Management Machine to carry out charging of the refrigerant system. If a R-134a Refrigerant Management Machine is not available, refrigerant system charging may be accomplished using a separate Automatic Refrigerant Charging Meter and R-134a Manifold Gauge Set.
NOTE:
Leaks in refrigerant system service equipment, hoses or gauges can cause a leak that may be misinterpreted as a problem with the vehicle's refrigerant system. It is necessary to leak-test all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are present.
- 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 in this service information.
- Connect a R-134a Refrigerant Management Machine to the low-side and high-side service gauge port valves following the operating instructions provided by the equipment manufacturer.
- Set the refrigerant charge amount, and charge the refrigerant system following the instructions provided by the equipment manufacturer.
NOTE:
Motorcraft® Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft® 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. For additional information, refer to REFRIGERANT OIL ADDING in this service information.
NOTE:
Do not use the R-134a Refrigerant Management Machine built-in oil injection system to inject Motorcraft Electric A/C Compressor Oil to the refrigerant system on hybrid vehicles equipped with an electric Air Conditioning (A/C) compressor if it has been previously used to inject PAG oil. For hybrid vehicles, use only clean manual injection tools. Injection of Motorcraft Electric A/C Compressor Oil into a hybrid vehicle with equipment previously used with PAG oil will contaminate and damage the hybrid A/C system.
