Chevrolet Cruze Repair Manual: Waterleak Test Preparation
- GM 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 a 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, rear compartment lid or
liftgate area this does not necessarily indicate a bad
weatherstrip. An adjustment to these areas may resolve the condition.
