Procedure: Leak Detected (All Models)

1. The shut-off valve must still be activated.
2. Detach the line from the purge valve on the intake manifold.
3. Pressurize the system further as described in the Kent-Moore instruction manual.
4. Detect the leak with the Ultrasonic Leak Detector (J41416). Start from the line detached from the intake manifold and work through the lines and components in the system. Perform a visual inspection at the same time.
5. Adjust the sensitivity of the detector to filter out ambient, in many cases, interfering noise.
6. When the leak has been detected and rectified, check the integrity of the system again.
7. Restore the car to its original state.
