For 1990-2009 cars

• | SGM vehicles are designed for operation under normal environmental conditions.

• | Design criteria for sealing material and components takes into account the sealing strength with the requirement of natural factors. However, these specifications have not taken into consideration any artificial conditions such as high pressure vehicle wash.

• | The water leakage test procedure is related to natural elements and can determine the vehicle performance under normal operation conditions.

• | The first step of leakage diagnosis is to determine the leakage happening conditions. If the general leakage position can be found, water hose or pneumatic hose may be used to separate the ingress point. Certain trim panels or components may need to be removed in order to repair the leakage.

• | If leakages are found around the door, window, trunk lid, or liftgate area, bad weatherstrips may not necessarily be the leakage cause. Adjustment to these areas may resolve the problem.

1. Assemble the water test stand as shown.
2. Position the stands as shown.

The water spray from the stands should overlap the vehicle as shown.

3. Have an assistant inside the vehicle during the test to locate any leakage.
4. The water pressure at the nozzle should maintain a 155 kPa (22 psi), for at least 4 minutes.
5. Aim the water spray 30 degrees down and 45 degrees toward the rear to check the windshield.
6. Aim the water towards the corner of the windshield.
7. To check the side windows for leakage, position the water test stand towards the center of the rear quarter, aiming the water spray 30 degrees down and 45 degrees toward the rear.
8. To check the rear windows, aim the water spray 30 degrees down and 30 degrees toward the front.
