GENERAL PROCEDURES
Electronic Leak Detection
CAUTION: Good ventilation is necessary in the area where electronic A/C leak testing is to
be carried out. If the surrounding air is contaminated with refrigerant gas, the leak detector will
indicate this gas all the time. Odors from other chemicals such as anti- freeze, diesel fuel, disc
brake cleaner, or other cleaning solvents can cause the same problem. A fan, even in a well-
ventilated area, is very helpful in removing small traces of contamination from the air that
might affect the leak detector.
1. NOTE: The system pressure should be between 413- 551 kPa (60-80 psi) at 24°C (75°F) with
the engine off.
Leak test the refrigerant system using the Refrigerant Leak Detector. Follow the instructions
included with the leak detector for handling and operation techniques.
2. If a leak is found, discharge and recover the refrigerant. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
z Repair the system.
z Test the system for normal operation.
