DIAGNOSIS
WATERLEAK DIAGNOSIS
The repair of waterleaks in the body requires proper test-
ing and diagnosis. Repair waterleaks by adjusting the mis-
aligned parts and using the proper repair materials. 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 compart-
ment. Second, test the area for the source of the leak us-
ing the following testing methods. If the general leak area
is found, determine the exact entry point of the leak by us-
ing 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 necessary to remove some inte-
rior 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 repairs more
difficult. Continue localized testing in the general area in
order to ensure that all leaks are found.
