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.

1. Apply soapy water to the outside of the suspected leak area.
2. Apply air pressure using an air hose from inside of the vehicle.

•	Do not exceed 205 kPa (30 psi) of air pressure.

•	Do not apply air pressure unless the urethane has completely cured.




3. Watch for bubbles on the outside of the vehicle at the suspected leak area.
4. Mark the leak area.
