Five Hundred AWD V6-3.0L VIN 1 (2005)
2. Verify that the valves on the fluorescent dye injector are closed.
3. Fill the fluorescent dye injector reservoir with 7 ml (0.25 oz) of fluorescent dye.
4. Install the fluorescent dye injector between the low-pressure service gauge port valve and the R-134a refrigerant service center or manifold gauge
set.
5. Open all valves and inject the fluorescent dye into the refrigerant system.
6. When fluorescent dye injection is complete, close all valves.
7. Recover the refrigerant from the R-134a fluorescent dye injector.
8. Remove the fluorescent dye injector from the low-pressure service gauge port valve and the R-134a A/C refrigerant service center or manifold
gauge set.
Fluorescent Dye Injection - Using a Dye Injector Loop Kit
NOTE:
-
Fluorescent refrigerant system dye is added to the refrigerant system at the factory to assist in refrigerant system leak diagnosis using a
Rotunda-approved ultraviolet blacklight. It is not necessary to add additional dye to the refrigerant system before diagnosing leaks, even if a
significant amount of refrigerant has been removed from the system. Replacement suction accumulators and receiver/driers are shipped with a
fluorescent dye "wafer" included in the desiccant bag which will dissolve after approximately 30 minutes of continued A/C operation. It is not
necessary to add dye after flushing or filtering the refrigerant system because a new suction accumulator or receiver/drier is installed as part of the
flushing or filtering procedure. Additional refrigerant system dye should only be added if more than 50% of the refrigerant system lubricant
capacity has been lost due to a fitting separation, hose rupture or other damage.
-
Before using the R-134a fluorescent dye injector for the first time, refer to the equipment manufacturers instructions on evacuation of
non-condensable gasses from the hoses.
-
Refrigerant system pressure should be between 413-551 kPa (60-80 psi) at 24°C.
1. Verify that the valves on the deluxe injector loop kit are closed.
