Refrigerant Oil Adding

2004 Ford Econoline E150, Van Cargo, 4.6 WSECTION Refrigerant Oil Adding
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: 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.
  1. Refer to the chart below for refrigerant oil adding amounts and methods of installation.
REFRIGERANT OIL ADDING AMOUNTS AND METHODS OF INSTALLATION

Component PAG Oil Amount Method of Adding
A/C Compressor See heading below Add directly to A/C compressor before installation
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
Evaporator Core Orifice or Thermostatic Expansion Valve 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.
