Refrigerant System Evacuation For Ford, Mercury and Lincoln?


The procedure is similar for Ford Crown Victoria, Mercury Grand Marquis, Lincoln Town Car.          

Refrigerant System Evacuation Using An R-134A Manifold Gauge Set

CAUTION
Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

  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 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 29.5 inches Hg (99.4 kPa) of vacuum and as close to 30 inches Hg (101.1 kPa) as possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
  5. Close the high-side and low-side valves on the manifold gauge set (not the service gauge port valves) and turn off the vacuum pump.
  6. 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.

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.

CAUTION
Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

  1. Connect an R-134a service center 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 29.5 inches Hg (99.4 kPa) of vacuum and as close to 30 inches Hg (101.1 kPa) 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.

This will help.
Thanks.
