For 1990-2009 cars

• | Holden vehicles are designed to operate under normal environmental conditions.

• | The design criteria for sealing materials and components takes into consideration the sealing forces required to withstand the natural elements. These specifications cannot take into consideration any artificial conditions, i.e. high pressure car washes.

• | The water leak test procedure has been correlated to the natural elements and will determine the ability of a vehicle to perform under normal operating conditions.

• | The first step in diagnosing a leak is determining the conditions under which the leak occurs. If the general leak area can be found, the exact entry point can be isolated using a water hose or an air hose. Some trim panels or components may need to be removed in order to repair the leak.

• | If leaks are found around a door, door window, or boot lid area this does not necessarily indicate a bad weatherstrip. An adjustment to these areas may resolve the condition.

1. Have an assistant inside of the vehicle during the test in order to locate any leaks.
2. Adjust the hose nozzle to simulate rainfall.
3. The water pressure at the nozzle should maintain a 155 kPa (22 psi), for at least 4 minutes.
4. In order to check the windscreen, aim the water spray 30 degrees down and 45 degrees toward the rear.
5. Aim the water towards the corner of the windshield.
6. In order to check the side windows for leaks aim the water spray 30 degrees down and 45 degrees toward the rear.
7. In order to check the rear windscreen, aim the water spray 30 degrees down and 30 degrees toward the front.
