DESCRIPTION

This bulletin describes how to use florescent 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.

REPAIR PROCEDURE

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.The misuse of tracer dye can lead to misdiagnosis and unneccessary parts replacement.

2. After repairing the leak, clean the area that is covered with A/C tracer dye.

NOTE: Cleaning the area 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.

• Flushing or changing the A/C oil is not neccessary.

• Small amounts of the tracer dye will be found in the Recovery/Recycling tank if recovery is neccessary.
