Localized Waterleak Testing

Localized Waterleak Testing

Spot Test





Localized testing may be made with either water or air. Begin the test at the base of the suspected area and continue up slowly until the leak is located.

Important: Pinpoint the leak area before any repair is made. Random repair may only temporarily restrict water entry and make future diagnosis and repair more difficult.


Continue localized testing in the same general area to confirm that all of the leaks have been located.

Water Hose Test





* Have a helper inside the vehicle to detect the actual leak point.
* Use unrestricted water flow (no nozzle).
* Begin at the base of the suspected leak area and move upward slowly.

Air Hose Test





* Apply a bubble solution, liquid soap and water, to the suspected area.
* Apply air pressure with an air hose from inside the vehicle. Do not exceed 205 kPa (30 psi).
* Observe for bubbles on the outside at the suspected leak area.

Waterleak Repair





To locate the exact leak point or to repair the leak, it may be necessary to remove some interior trim panels or components.

After completion of any waterleak repair, the general area should be retested using the waterstand test. Do not use an air hose or a water hose to test the repaired areas as the repair material may dislodge under abnormal pressure application.
