Fluorescent Dye Injector
NOTE: Vehicles built 07/1999 onwards have a fluorescent tracer dye tablet inserted into
the air conditioning (A/C) system. If tracer dye is present, there is a green cross on the
suction accumulator.
NOTE: On vehicles built up to 07/1999 tracer dye must be added.
NOTE: Some vehicles may have signs of refrigerant oil at the spring lock couplers. This
may be caused from the assembly process which applies to the fittings before installation
to aid in assembly. When a spring lock coupler is suspected of leaking, always wipe the
fitting clean and verify the leak with R-134a Automatic Calibration Halogen Leak Detector.
NOTE: The exact location of leaks can be pinpointed by the bright yellow - green glow of
the tracer dye. Since more than one leak may exist, always inspect each component.
Transit/Tourneo Connect 2002.5 (06/2002-)
1. Using the dye injector, add 7.4 ml of Fluorescent
Tracer Dye.
2. Check for leaks using a 120 Watt UV Spot Lamp.
Always scan all components, fittings and lines of
the A/C system.
3. After the leak is found and repaired, remove any
traces of dye with a general purpose oil solvent.
4. Verify the repair by operating the system for
some minutes and inspecting with the UV lamp
again.
