Special Tool(s)

120 Watt 110 Volt UV Lamp 20C 164-R0721 or equivalent

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.
