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 antifreeze, diesel
fuel, disc brake cleaner or other cleaning solvents can cause the same problem. Using a fan to ventilate the area to be tested before proceeding
with the leak detection procedure is helpful in removing small traces of contamination from the air, but the fan should be turned off during
actual testing.
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 leak detector. Follow the instructions included with the leak detector for handling and operation
techniques.
2. If a leak is found, recover the refrigerant.
-
Repair the system.
-
Test the system for normal operation.
