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.

    • Have an assistant inside the vehicle in order to detect the actual leak point.
    • Use an unrestricted water flow (no nozzle).
    • Begin at the base of the suspected leak area and move upward slowly.
