Air Hose Test

Air Hose Test

Notice: The air hose test should only be used on fully cured urethane adhesive. Otherwise, damage to the urethane adhesive bead could result in additional leaks.

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.




1. Apply soapy water to the suspected area.

Important: Do not exceed 205 kPa (30 psi).

2. Apply air pressure using an air hose from inside the vehicle.




3. Inspect for bubbles on the outside at the suspected leak area.
