Fluorescent Dye Leak Detection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2012 Jaguar XFR, 2012 Jaguar XF, 2011 Jaguar XFR, 2011 Jaguar XF, and 2010 Jaguar XFR. However, it is still accessible from the selected car via links, so may be relevant.
    WARNING: Eye protection glasses supplied with the ultraviolet (UV) lamp should be used to protect eyesight from harm.
    NOTE: The air conditioning (A/C) system has an R-134a leak trace dye wafer incorporated into the desiccant bag. 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. If it is necessary to add dye (due to a severe leakage for example) use proprietary tracer dye injection equipment.
  1. Check for leaks using ultraviolet (UV) lamp.
  2. Check all components, fittings and lines of the A/C system.
  3. Carry out the repair. For additional information, Refer to: AIR CONDITIONING information. .
  4. After the leak is repaired, remove any traces of leak trace dye with a general purpose oil solvent.
  5. Check the A/C system for correct operation.
  6. Verify the repair by operating the system for a short time and inspecting with the (UV) lamp.
