If the source of the leak is not obvious, use a water test stand and perform generalized leak test method. Once the general leak area is located, use a water hose or an air hose and perform one of the localized test procedures to pinpoint the specific leak area. Refer to Water Hose Test or Air Hose Test .

1. Subject the vehicle to a water spray of 155 KPa (22 psi) for 10 to 20 minutes.
