NOTE: Ford Motor Company vehicles are produced with R-134a 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.
