F 350 2WD Super Duty V10-6.8L (2009)
accomplished using a separate recovery station, Vacuum Pump, Automatic Refrigerant Charging Meter and R-134a Manifold Gauge Set.
NOTE: Ford Motor Company recommends the use of R-134a refrigerant management equipment that meets the requirements of the SAE J2788
standard.
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.
6.4L diesel vehicles
1. Remove the engine Air Cleaner (ACL) element.
All vehicles
2. Prior to recovering, verify the purity of the refrigerant. For additional information, refer to Refrigerant Identification Testing See: Heating and Air
Conditioning/Testing and Inspection/Component Tests and General Diagnostics/Refrigerant Identification Testing.
3. Connect an R-134a Refrigerant Management Machine to the low- and high-pressure service gauge port valves following the operating instructions
provided by the equipment manufacturer.
4. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer.
5. Once the R-134a Refrigerant Management Machine has recovered the refrigerant, switch OFF the power supply.
6. 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.
7. If the system does lose vacuum, repeat Steps 3 through 5 until the vacuum level remains stable for 2 minutes.
8. 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, refrigerant system recovery, evacuation and charging may be
accomplished using a separate recovery station, Vacuum Pump, Automatic Refrigerant Charging Meter and R-134a Manifold Gauge Set.

2. Connect an 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. 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.
4. 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.
