Air Hose Test

Caution: 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. Using a liquid detergent, diluted with water in a spray bottle, spray the window at the edges. Begin at the bottom and gradually move up and across the top.

Note: The compressed air should not exceed 205 kPa (30 psi).

1. 1
   Have an assistant inside of the vehicle with an air hose.
2. 2
   Have the assistant aim the compressed air at the suspected areas.

Bubbles will form in the soap solution at the location of the leak.
