Ford Mustang (1999-2004) Service Manual: Electronic Leak Detection

Special Tool(s)

H10PM Refrigerant Leak Detector With Battery 216-00001 or equivalent

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 wellventilated 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 24C (75F) 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.
