E715 EN

Special Tool(s)
R-134a Manifold Gauge Set
or equivalent
NOTE: Since July 1999 vehicles have a fluores-
cent tracer dye tablet inserted into the A/C sys-
tem. If tracer dye is present, there is a green
cross on the suction accumulator.
NOTE: If it is necessary to add tracer dye, use
the dye injector. A/C systems require 7.4 ml of
Fluoro-Light / P Fluorescent Tracer Dye. For
additional information,
refer to Specification in this section
NOTE: Some vehicles may have signs of refrig-
erant oil at the spring lock couplers. This may be
caused from the assembly process, which ap-
plies to the fittings before installation to aid in
assembly. When a spring lock coupler is sus-
pected of leaking, always wipe the fitting clean
and verify the leak with R-134a Automatic Cali-
bration Halogen Leak Detector.
NOTE: The exact location of leaks can be pin-
pointed by the bright yellow-green glow of the
tracer dye. Since more than one leak may exist,
always inspect each component.
1. Check for leaks using a 120 Watt UV Spot
Lamp. Always scan all components, fittings
and lines of the A/C system.
2. After the leak is found and repaired, remove
any traces of dye with a general purpose oil
solvent.
3. Verify the repair by operating the system for
some minutes and inspecting with the UV
lamp again.
