8. Close the high-pressure service valve to allow the pressure inside the R-134a Loop/Add On Injector Kit-Set to equalize with the suction side of the
refrigerant system.
NOTE: Close the valves on the R-134a Loop/Add On Injector Kit-Set while the A/C compressor is operating.
9. Close the valves on the R-134a Loop/Add On Injector Kit-Set.
NOTE: Leave all valves on the R-134a Loop/Add On Injector Kit-Set closed when not in use.
10. Disconnect the high-pressure and low-pressure service valves and remove the R-134a Loop/Add On Injector Kit-Set from the vehicle.
Fluorescent Dye Detection
NOTE: Ford Motor Company vehicles are produced with R-134a fluorescent dye installed in the refrigerant system from the factory. The location of
leaks can be pinpointed by the bright yellow-green glow of the fluorescent dye under a UV lamp. Since more than one leak can exist, make sure to
inspect each component, line and fitting in the refrigerant system for a leak.
1. Check for leaks using a Rotunda-approved UV lamp and dye enhancing glasses.
-
Inspect all components, lines and fittings of the refrigerant system.
2. If a leak is found, recover the refrigerant. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging
in this section.
3. Repair the refrigerant system leak(s).
4. Evacuate and charge the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and
Charging in this section.
5. After the leak(s) is repaired, remove any traces of fluorescent dye with a general purpose oil solvent.
NOTE: Use of dye-enhancing glasses or goggles greatly improves the detection of the dye under the UV lamp.
NOTE: Not all UV lamps will fluoresce the dye used in Ford vehicles. All Rotunda UV lamps are optimized to fluoresce the dye.
6. Verify the repair by running the vehicle for a short period of time and rechecking the area of the leak with a Rotunda-approved UV lamp.
