  Tracer Dye Leak Detection  

120 Watt 110 Volt UV Lamp 20 Degree Celsius


NOTE: Ford Motor Company vehicles are produced with a permanent leak tracer dye incorporated into the A/C system. The location of leaks can be pinpointed by the bright yellow-green glow of the tracer dye. Since more than one leak can exist, always inspect each component.


  1. Check for leaks using a 120 Watt UV spot lamp.
    • Scan all components, fittings and lines of the A/C system.
  1. After the leak is repaired, remove any traces of tracer dye with a general purpose oil solvent.


  1. Verify the repair by operating the system for a short time and inspect with the UV spot lamp.
