2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
CAUTION:
If repairing the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
3. Connect the injector tool to the A/C LOW PRESSURE side service valve.
4. Start the engine and switch the A/C ON and fan ON.
5. While the A/C is 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 manufacturer's oper-
ating instructions.
6. With the engine still running, disconnect the injector tool from the low-pressure service valve.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system lubricant. Depending
on the leak size, operating conditions and location of the leak, it may take from a few minutes to a few
days for the dye to penetrate the leak and become visible.
Electronic Refrigerant Leak Detector EJS002TK
PRECAUTIONS FOR HANDLING THE LEAK DETECTOR
When performing a refrigerant leak check, use a electronic refriger-
ant leak detector (J-41995) or equivalent. Ensure that the instrument
is calibrated and set properly per the manufacturer's operating
instructions.
The leak detector is a delicate device. In order to use the leak detec-
tor properly, read the manufacturer's operating instructions and per-
form any specified maintenance.
1. Position the leak detector probe approximately 5 mm (3/16 in)
away from the point to be checked.
2. When testing, circle each fitting completely with the leak detec-
tor probe.
