Fluorescent Dye Leak Detection (G179002)

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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.

    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 the appropriate repair 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.
