Refrigerant Oil Adding
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
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.
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.
NOTE:
During normal Air Conditioning (A/C) operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If certain components of the system are removed, some of the refrigerant oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part.
- Refer to the table below for refrigerant oil adding amounts and methods of installation.REFRIGERANT OIL ADDING AMOUNTS REFERENCE TABLE
Component Oil Amount Method of Adding A/C Compressor - Non-Hybrid Refer to ADDING REFRIGERANT OIL AFTER A/C COMPRESSOR REPLACEMENT - NON-HYBRID Add directly to A/C compressor before installation Electric A/C Compressor - Hybrid Refer to ADDING REFRIGERANT OIL AFTER A/C COMPRESSOR REPLACEMENT - HYBRID Inject to low-side service port during system charging Receiver/Drier Desiccant Cartridge 60 ml (2 fl oz) added to the amount collected during refrigerant recovery Inject to low-side service port during system charging Evaporator Core 45 ml (1.5 fl oz) added to the amount collected during refrigerant recovery Add directly to evaporator core inlet tube or inject to low-side service port during system charging Condenser Core 60 ml (2 fl oz) added to the amount collected during refrigerant recovery Add directly to condenser core inlet or inject to low-side service port during system charging Thermostatic Expansion Valve (TXV) The amount collected during refrigerant recovery Inject to low-side service port during system charging A/C Pressure Relief Valve 60 ml (2 fl oz) added to the amount collected during refrigerant recovery Inject to low-side service port during system charging Refrigerant Hose/Line 60 ml (2 fl oz) added to the amount collected during refrigerant recovery (1) Inject to low-side service port during system charging O-ring Leak Repair 60 ml (2 fl oz) added to the amount collected during refrigerant recovery (2) Inject to low-side service port during system charging Service Port Leak Repair 60 ml (2 fl oz) added to the amount collected during refrigerant recovery Inject to low-side service port during system charging (1) If an excessive amount of refrigerant oil is lost due to a hose rupture/separation or other damage, the total system refrigerant oil capacity must be added. (2) The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the refrigerant oil amount by the number of O-ring leaks being repaired.
