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.

DIAGNOSIS
WINDNOISE DIAGNOSIS
CAUTION : An assistant should drive the vehicle
while the technician checks for the location of the
windnoise, in order to prevent personal injury or ve-
hicle damage.
A test drive in the vehicle is necessary to accurately deter-
mine the location of the windnoise. Often there is a primary
leak and secondary leaks. Failure to repair all leaks will
only reduce the windnoise, not eliminate it.
During the test drive the technician should bring the follow-
ing items to aid in determining the location of the wind-
noise.
S A mechanics stethoscope or vacuum hose
S Masking tape
S Strip caulk
S A china marking pencil
S A screwdriver
Perform the following steps in order to conduct the road
test:
1. Choose a route that includes smooth straight
streets that run in all four directions (north, south,
east, and west).
2. Choose streets with little traffic or noise that would
interfere with the test.
3. Drive the vehicle at the speeds at which the noise
was noticed by the customer or until the noise is
produced. Do not exceed legal speed limits.
4. The windnoise is external if any of the following
conditions occur:
S The windnoise is caused by the wind.S The windnoise can be heard with the door glass
lowered and while the vehicle is being driven.
S The windnoise is eliminated when tape is placed
over various moldings and gaps.
5. Internal windnoise is air leaving the vehicle and
should be repaired in the following manner.
S In order to locate the leak, tape off the body lock
pillar pressure relief valves. This will cause air
pressure to build up inside the vehicle and en-
hance the windnoise.
S Use a stethoscope or a vacuum hose to locate
the leak.
S Temporarily repair the leak with masking tape.
S Continue testing in order to determine if the
noise has been eliminated or if other leaks exist.
S When all leaks have been found, return to the
shop and make permanent repairs with the
proper alignment techniques and sealing materi-
als.
