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 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. |
