The procedure is below.


Charging the System
REFRIGERANT OIL ADDING
USING AN R-134A MANIFOLD GAUGE SET
USING AN R-134A SERVICE CENTER

The details are as follows :---


Refrigerant Oil Adding



Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

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 PAG 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 Oil Specifications for refrigerant oil adding amounts and methods of installation.
Adding Refrigerant Oil After A/C Compressor Replacement
Service A/C Compressors Shipped With Clutch And Pulley
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
Rotate the old A/C compressor shaft 6 to 8 revolutions while collecting oil in a clean measuring device.


If the amount of oil drained from the old A/C compressor is less than 89 ml (3 oz), remove 118 ml (4 oz) from the new A/C compressor.
If the amount of oil drained from the old A/C compressor is 89 ml (3 oz), remove 89 ml (3 oz) from the new A/C compressor.
If the amount of oil drained from the old A/C compressor is 118 ml (4 oz), remove 59 ml (2 oz) from the new A/C compressor.
If the amount of oil drained from the old A/C compressor is 148 ml (5 oz), remove 29 ml (1 oz) from the new A/C compressor.
If the amount of oil drained from the old A/C compressor is greater than 148 ml (5 oz), remove 0 ml (0 oz) from the new A/C compressor.

Service A/C Compressors Shipped Without Clutch And Pulley
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
Rotate the A/C compressor shaft 6 to 8 revolutions while collecting oil in a clean measuring device.


If the amount of oil drained from the old A/C compressor is between 85-142 ml (3-5 oz), pour the same amount plus 30 ml (1 oz) of clean PAG Refrigerant Compressor Oil (R-134a Systems) (YN-12-D) WSH M1C231-B or equivalent into the new A/C compressor.
If the amount of oil that was removed from the old A/C compressor is greater than 142 ml (5 oz), pour the same amount drained of clean PAG Refrigerant Compressor Oil (R-134a Systems) or equivalent into the new A/C compressor.
If the amount of oil that was removed from the old A/C compressor is less than 85 ml (3 oz), pour 85 ml (3 oz) of clean A/C Refrigerant Compressor Oil (R-134a Systems) or equivalent into the new A/C compressor.

Adding Refrigerant Oil After Multiple Component Replacement After A/C System Contamination
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

NOTE
This refrigerant oil adding method is to be used when a new A/C compressor, suction accumulator or receiver drier and evaporator core orifice or TXV have been installed due to system contamination and the A/C system has been flushed.


NOTE
Service A/C compressors are shipped without refrigerant oil.

  1. Add 60 ml (2 fl oz) directly to the new A/C compressor suction port.
  2. Inject the total vehicle PAG oil capacity minus 60 ml (2 fl oz) to the low-side service port during system charging. For the total PAG oil capacity specification, refer to the Oil Specifications in this section.
Adding Refrigerant Oil After New Suction Accumulator Or Receiver/Drier Replacement
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

NOTE
This refrigerant oil adding method is to be used when a new suction accumulator or receiver drier only has been installed. If a new A/C compressor and evaporator core orifice or TXV have also been installed due to system contamination, refer to the appropriate heading.

  1. Drill one 12.7 mm (1/2 in) hole in the old suction accumulator or receiver/drier cylinder and drain the oil into a clean measuring cup.
  2. Add the same quantity of new PAG oil, plus the amount collected during refrigerant recovery and 60 ml (2 fl oz).
Oil Specifications
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
When replacing the A/C Compressor, refer to Adding Refrigerant Oil After A/C Compressor Replacement. Oil should be added by adding or removing directly through A/C compressor low-side port before installation.
When replacing the Suction Accumulator or Receiver/Drier, refer to Adding Refrigerant Oil After New Suction Accumulator or Receiver/Drier Replacement. Oil should be added directly to suction accumulator inlet port or inject to low-side service port during system charging.
When replacing the Evaporator Core, the PAG oil amount should be 45 ml (1.5 fl oz) added to the amount collected during refrigerant recovery. Oil should be added directly to evaporator core inlet tube or inject to low-side service port during system charging.
When replacing the Condenser Core, the PAG oil amount should be 60 ml (2 fl oz) added to the amount collected during refrigerant recovery. Oil should be added directly to condenser core inlet or inject to low-side service port during system charging.
When replacing the Evaporator Core Orifice or Thermostatic Expansion Valve (TXV) , the PAG oil amount should be the amount collected during refrigerant recovery. Oil should be injected to low-side service port during system charging.
When replacing the A/C Pressure Relief Valve, the PAG oil amount should be 60 ml (2 fl oz) added to through the amount collected during refrigerant recovery. Oil should be injected to low-side service port during system charging.
When replacing the Refrigerant Hose/Line, the PAG oil amount should be 60 ml (2 fl oz) added to the amount collected during refrigerant recovery If an excessive amount of PAG oil is lost due to a hose rupture/separation or other damage, the total system PAG oil capacity must be added. Oil should be injected to low-side service port during system charging.
When performing an O-ring Leak Repair, the PAG oil amount should be 60 ml (2 fl oz) added to the amount collected during refrigerant recovery The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the PAG oil amount by the number of O-ring leaks being repaired. Oil should be injected to low-side service port during system charging.
When performing a Service Port Leak Repair, the PAG oil amount should be 60 ml (2 fl oz) added to the amount collected during refrigerant recovery. Oil should be injected to low-side service port during system charging.

Using An R-134A Manifold Gauge Set



Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

NOTE
Ford Motor Company recommends use of an A/C service center to carry out recovery, evacuation and charging of the refrigerant system. If an A/C service center is not available, refrigerant system recovery, evacuation and charging may be accomplished using a separate recovery station, vacuum pump, charging meter and 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.
  2. Assemble the R-134a manifold gauge set, automatic refrigerant charging meter and R-134a supply tank following the automatic refrigerant charging meter operating instructions.
  3. Charge the refrigerant system following the automatic refrigerant charging meter operating instructions.
  4. If the refrigerant flow stops before the refrigerant charge is complete, start the engine, select MAX A/C operation and allow the refrigerant charge to complete.
