Electronic Leak Detection

WARNING: This page is about a different car, the 2013 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

SPECIAL TOOLS

	Infrared Refrigerant Leak Detector 023-00186 or equivalent
	Dual Mode Refrigerant Gas and UV Dye Leak Detector 339-00002 or equivalent

NOTE: 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. Fumes from other chemicals such as antifreeze, diesel fuel, disc brake cleaner or other cleaning solvents can cause a false reading. 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.

NOTE: R-134a is heavier than air, and will tend to move downward from the source of the leak if present. It is possible that a leak may not be detected if the leak detector tip is held above the leaking fitting, line or component. Always be sure to thoroughly leak test below the fitting, line or component for the presence of R-134a as well as leak testing above and around.

NOTE: The system pressure should be between 413-551 kPa (60-80 psi) at 24°C (75°F) with the engine off and cool. The pressure reading may be higher if the engine is hot.

Special Tool(s): Infrared Refrigerant Leak Detector 023-00186 or Dual Mode Refrigerant Gas and UV Dye Leak Detector 339-00002.

Leak test the refrigerant system. Follow the instructions included with the Infrared Refrigerant Leak Detector or Dual Mode Refrigerant Gas and UV Dye Leak Detector for handling and operation techniques.
