Refrigerant Oil Adding

WARNING: This page is about a different car, the 2015 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the Refrigerant Identification Equipment before recovering of any vehicle's refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of contamination. If the vehicle's refrigerant is contaminated, refer the customer to the service facility that carried out the last A/C service. If the customer wishes to pay the additional cost, use the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. Dispose of all contaminated A/C refrigerant as hazardous waste in accordance with all federal, state and local regulations. For all equipment, follow the equipment manufacturer procedures and instructions.
NOTE: Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) only must be used as a refrigerant system lubricant. Addition of any oil other than Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) to the refrigerant system will damage the A/C compressor and contaminate the refrigerant system.
NOTE: During normal 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.
NOTE: Make sure the equipment is clean and free of foreign material.

  1. 1.

    Refer to the chart below for refrigerant oil adding amounts and methods of installation.

    Refrigerant Oil Adding (When new components are installed) 

    Component Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) Oil Amount (fl oz (ml)) Method of Adding
    After installing the A/C Compressor. Service compressor contains full system charge of oil. Oil matching required plus amount collected during recovery. Add directly to A/C compressor before installation
    After installing the receiver drier. 2 fl oz (60 ml) plus the amount collected during refrigerant recovery. Inject to low-side service port during system charging.
    After installing the receiver drier element. 1 fl oz (30 ml) plus the amount collected during refrigerant recovery. Inject to low-side service port during system charging.
    After installing the condenser core. 1.5 fl oz (45 ml) plus the amount collected during refrigerant recovery. Add directly to inlet port or inject to low-side service port during system charging.
    After installing the condenser core, and the receiver drier element 2 fl oz (60 ml) plus the amount collected during refrigerant recovery. Add directly to inlet port or inject to low-side service port during system charging.
    After installing the evaporator core. 1.5 fl oz (45 ml) plus the amount collected during refrigerant recovery. Add directly to inlet port or inject to low-side service port during system charging.
    After installing/reassembling the thermostatic expansion valve. Amount collected during refrigerant recovery. Inject to low-side service port during system charging.
    After installing a refrigerant Hose/Line. 2 fl oz (60 ml) plus the amount collected during refrigerant recovery (1) Inject to low-side service port during system charging.
    After an O-ring Leak Repair. 1 fl oz (30 ml) plus the amount collected during refrigerant recovery (2) Inject to low-side service port during system charging.
    After a service port leak repair. Amount collected during refrigerant recovery. Inject to low-side service port during system charging.
    (1) If an excessive amount of Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) is lost due to a hose rupture/separation or other damage, the total system Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) capacity must be added. Also, it is necessary to replace the receiver drier.
    (2) The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the Motorcraft ® PAG Refrigerant Compressor Oil (YN-12-D) amount by the number of O-ring leaks being repaired.

  1. 2.

    Fill the system with the calculated quantity of new refrigerant oil in accordance with the Air Conditioning Service Unit manufacturer instructions.
