CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorEJS000VK
1. Check A/C system for leaks using the UV lamp and safety glasses (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionEJS000VL
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
3. Connect the injector tool to the A/C LOW PRESSURE side service fitting.
4. Start engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye injector tool J-41459 (refer to the manufacture's operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system con-
nection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak, it may take from minutes to days for the dye to
penetrate a leak and become visible.
Electronic Refrigerant Leak DetectorEJS000VM
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak detector
or equivalent. Ensure that the instrument is calibrated and set prop-
erly per the operating instructions.
The leak detector is a delicate device. In order to use the leak detec-
tor properly, read the operating instructions and perform any speci-
fied maintenance.
