Refrigerant Oil Adding (when new components are installed)
Component | Motorcraft® PAG Refrigerant Compressor Oil (YN-12-D) 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. | Refer to oil adding steps above. |
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 a . | 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 b . | 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. |
a 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. | ||
b 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. | ||
