Taurus AWD V6-3.5L (2009)
equipment, follow the equipment manufacturer procedures and instructions.
NOTE: Ford Motor Company recommends the use of R-134a refrigerant management equipment that meets the requirements of the SAE J2788
standard.
NOTE: Ford Motor Company recommends use of a R-134a Refrigerant Management Machine to carry out recovery. If a R-134a Refrigerant
Management Machine is not available, refrigerant system recovery may be accomplished using a separate recovery station.
NOTE: Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum 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. Prior to recovering, the purity of the refrigerant must be verified. For additional information, refer to Refrigerant Identification Testing See:
Heating and Air Conditioning/Testing and Inspection/Component Tests and General Diagnostics/Refrigerant Identification Testing.
2. Connect a R-134a Refrigerant Management Machine to the low- and high-pressure service gauge port valves following the operating instructions
provided by the equipment manufacturer.
3. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer. Note the amount of oil
removed during the refrigerant recovery (if any). Add that same amount back into the system once repairs are complete.
4. Once the R-134a Refrigerant Management Machine has recovered the refrigerant, switch OFF the power supply.
5. Allow the system to set for about 2 minutes, and observe the system vacuum reading. If the vacuum is not lost, disconnect the recovery equipment.
6. If the system does lose vacuum, repeat Steps 3 through 5 until the vacuum level remains stable for 2 minutes.
7. Carry out the required repairs.
Refrigerant System Evacuation Using a R-134a Refrigerant Management Machine
NOTE: Ford Motor Company recommends use of a R-134a Refrigerant Management Machine to carry out recovery, evacuation and charging of the
refrigerant system. If a R-134a Refrigerant Management Machine is not available, evacuation may be accomplished using a separate Vacuum Pump and
R-134a Manifold Gauge Set.
NOTE: Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum 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. Connect a R-134a Refrigerant Management Machine to the low- and high-pressure service gauge port valves following the operating instructions
provided by the equipment manufacturer.
2. Evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum and as close to 101.1 kPa (30 in-Hg) as possible.
Continue to operate the Vacuum Pump for a minimum of 45 minutes.
3. Turn OFF the Vacuum Pump. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If vacuum is not held for
5 minutes, leak test the system, repair the leak and evacuate the system again.
Refrigerant System Evacuation Using a R-134a Manifold Gauge Set and Vacuum Pump
NOTE: Ford Motor Company recommends use of a R-134a Refrigerant Management Machine to carry out evacuation of the refrigerant system. If a
R-134a Refrigerant Management Machine is not available, refrigerant system evacuation may be accomplished using a separate Vacuum Pump and
R-134a Manifold Gauge Set.
NOTE: Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum 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. Connect the R-134a Manifold Gauge Set to the low-side and high-side service gauge port valves.
2. Connect the center (yellow) hose from the R-134a Manifold Gauge Set to the suction port on the Vacuum Pump.
3. Open all valves on the R-134a Manifold Gauge Set and both service gauge port valves.
4. Turn on the Vacuum Pump and evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum and as close to
101.1 kPa (30 in-Hg) as possible. Continue to operate the Vacuum Pump for a minimum of 45 minutes.
