Check Refrigerant Leakage Using Fluorescent Leak Detection Dye
WARNING: This page is about a different car, the 2016 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
- Install a fender cover (1).
- Wear UV safety goggles (2) provided with refrigerant dye leak detection kit.
- Connect power cable (4) of UV lamp (6) to positive and negative terminals of the battery (3).
- Press UV lamp switch (5) and check A/C system for refrigerant leakage. (Where refrigerant leakage occurs, fluorescent leak detection dye appears in green color.)WARNING:
Do not look directly into UV lamp light source.
NOTE:- For continuous operating time of UV lamp, follow the manufacturer operating instructions.
- Illuminate piping joints from different angles using UV lamp and check that there is no leakage.
- Use a mirror in area that is difficult to see to check refrigerant leakage.
- Refrigerant leakage from evaporator can be detected by soaking cotton swab or a similar material with drain hose water and illuminating it using UV lamp.
- Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may fluoresce. Be careful not to misidentify leakage.
- Repair or replace parts where refrigerant leakage occurs and wipe off fluorescent leak detection dye.NOTE:
Completely wipe off fluorescent leak detection dye from gaps between parts, screw threads, and others using a cotton swab or similar materials.
- Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work.WARNING:
Do not look directly into UV lamp light source.
NOTE:- For continuous operating time of UV lamp, follow the manufacturer operating instructions.
- Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may fluoresce. Be careful not to misidentify leakage.
