9I – 2 WATERLEAKS
DIAGNOSTIC INFORMATION AND PROCEDURES
WATERLEAK DIAGNOSIS
The repair of waterleaks in the body requires proper
testing and diagnosis. Repair waterleaks by adjusting
the misaligned parts and using the proper repair materi-
als. First, determine what conditions cause the leak. For
example, the leak may occur only when the vehicle is
parked on an incline, or water may appear only in the
spare tire compartment. Second, test the area for the
source of the leak using the following testing methods. If
the general leak area is found, determine the exact entry
point of the leak by using a water hose or an air hose. If
the general leak area is not obvious, use the watertest
stands to determine the area of the leak. It may be nec-
essary to remove some interior trim panels or some
parts in order to locate the leaks.
Important: It is necessary to find the origin of all the
leaks before making any repairs. Random repairs may
stop the leak only temporarily and may make future re-
pairs more difficult. Continue localized testing in the gen-
eral area in order to ensure that all leaks are found.
