USING THE AUTOMATIC CALIBRATION HALOGEN LEAK DETECTOR

CAUTION: Good ventilation is necessary in the area where electronic A/C leak testing is to be performed. 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. Leak test the refrigerant system using the Automatic Calibration Halogen Leak Detector. Follow the instructions included with the leak detector for handling and operation techniques.

NOTE: System pressure should be between 413-551 kPa (60-80 psi) at 24°C (75°F) with the engine off.







2. If a leak is found, discharge and recover the refrigerant.
- Repair the system.
- Test the system for normal operation.

USING TRACER DYE

NOTE: Ford Motor Company vehicles are produced with a permanent leak tracer dye incorporated into the A/C system. The location of leaks can be pinpointed by the bright yellow-green glow of the tracer dye. Since more than one leak can exist, always inspect each component.







1. Check for leaks using a 120 Watt UV Spot Lamp.
- Scan all components, fittings and lines of the A/C system.
2. After the leak is repaired, remove any traces of leak dye with a general purpose oil solvent.







3. Verify the repair by operating the system for a short time and inspecting with the UV spot lamp.
