DESCRIPTION
Use a fluorescent A/C leak detecting tracer dye and light for
finding minute, intermittent leaks.
NOTE: Most electronic leak detectors can detect small steady leaks,
but are ineffective on minute, intermittent leaks.

WHEN USING A/C TRACER DYE METHOD

1. Follow the A/C tracer dye manufacturers instructions.
NOTE: Different manufacturers have different methods for installing,
measuring and diagnosing with their particular product.
CAUTION:
* Use only a tracer dye that is compatible with the type of
refrigerant and oil in the vehicle's A/C system.
* Tracer dye can lead to misdiagnosis and unnecessary parts
replacement if used improperly.
2. After repairing the leak, clean the area that is covered with
A/C tracer dye.
NOTE: This will prevent a future technician from mistaking this
residue as a current leak.
3. When diagnosing an A/C leak on a vehicle that previously had tracer
dye installed, thoroughly clean the suspected area and re-verify
the leak prior to repairing.
4. After repairing the leak, evacuate and recharge the system as
outlined in the workshop manual.
NOTE: DO NOT add additional A/C tracer dye when recharging the
system.
a. Flushing or changing he A/C oil is not necessary.
