Refrigerant System Charging Using a R-134a Refrigerant Management Machine

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.
  1. Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to REFRIGERANT OIL ADDING .
  2. 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.
  3. Set the refrigerant charge amount, and charge the refrigerant system following the instructions provided by the equipment manufacturer.
