UV Leak Detector

1. Refer to: Air Conditioning (A/C) System Health and Safety Precautions (100-00 General Information, Description and Operation).

2. NOTE: Some vehicles may have signs of refrigerant oil at the spring lock couplers. The cause of this may be a procedure used in production before installation of the fittings in order to assist their assembly. When a spring lock coupler is suspected of leaking, always wipe the fitting clean and verify the leak with R-134a Automatic Calibration Halogen Leak Detector.

NOTE: The exact 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.

  • Locate the leaks. Check all components, fittings and lines of the A/C system for leaks.
