WATER LEAK TESTS
WARNING: DO NOT USE ELECTRIC SHOP LIGHTS
OR TOOLS IN WATER TEST AREA. PERSONAL
INJURY CAN RESULT.
When the conditions causing a water leak have
been determined, simulate the conditions as closely
as possible.
²If a leak occurs with the vehicle parked in a
steady light rain, flood the leak area with an open-
ended garden hose.
²If a leak occurs while driving at highway speeds
in a steady rain, test the leak area with a reasonable
velocity stream or fan spray of water. Direct the
spray in a direction comparable to actual conditions.
²If a leak occurs when the vehicle is parked on an
incline, hoist the end or side of the vehicle to simu-
late this condition. This method can be used when
the leak occurs when the vehicle accelerates, stops or
turns. If the leak occurs on acceleration, hoist the
front of the vehicle. If the leak occurs when braking,
hoist the back of the vehicle. If the leak occurs on left
turns, hoist the left side of the vehicle. If the leak
occurs on right turns, hoist the right side of the vehi-
cle. For hoisting recommendations (Refer to LUBRI-
CATION & MAINTENANCE/HOISTING -
STANDARD PROCEDURE).
WATER LEAK DETECTION
To detect a water leak point-of-entry, do a water
test and watch for water tracks or droplets forming
on the inside of the vehicle. If necessary, remove inte-
rior trim covers or panels to gain visual access to the
leak area. If the hose cannot be positioned without
being held, have someone help do the water test.
Some water leaks must be tested for a considerable
length of time to become apparent. When a leak
appears, find the highest point of the water track or
drop. The highest point usually will show the point of
entry. After leak point has been found, repair the
leak and water test to verify that the leak has
stopped.
Locating the entry point of water that is leaking
into a cavity between panels can be difficult. The
trapped water may splash or run from the cavity,
often at a distance from the entry point. Most water
leaks of this type become apparent after accelerating,
stopping, turning, or when on an incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use
a suitable mirror to gain visual access. A mirror canalso be used to deflect light to a limited-access area
to assist in locating a leak point.
BRIGHT LIGHT LEAK TEST METHOD
Some water leaks in the luggage compartment can
be detected without water testing. Position the vehi-
cle in a brightly lit area. From inside the darkened
luggage compartment inspect around seals and body
seams. If necessary, have a helper direct a drop light
over the suspected leak areas around the luggage
compartment. If light is visible through a normally
sealed location, water could enter through the open-
ing.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compart-
ment cannot be detected by water testing, pressurize
the passenger compartment and soap test exterior of
the vehicle. To pressurize the passenger compart-
ment, close all doors and windows, start engine, and
set heater control to high blower in HEAT position. If
engine can not be started, connect a charger to the
battery to ensure adequate voltage to the blower.
With interior pressurized, apply dish detergent solu-
tion to suspected leak area on the exterior of the
vehicle. Apply detergent solution with spray device or
soft bristle brush. If soap bubbles occur at a body
seam, joint, seal or gasket, the leak entry point could
be at that location.
DIAGNOSIS AND TESTING - WIND NOISE
Wind noise is the result of most air leaks. Air leaks
can be caused by poor sealing, improper body compo-
nent alignment, body seam porosity, or missing plugs
in the engine compartment or door hinge pillar areas.
All body sealing points should be airtight in normal
driving conditions. Moving sealing surfaces will not
always seal airtight under all conditions. At times,
side glass or door seals will allow wind noise to be
noticed in the passenger compartment during high
cross winds. Over compensating on door or glass
adjustments to stop wind noise that occurs under
severe conditions can cause premature seal wear and
excessive closing or latching effort. After a repair pro-
cedure has been performed, test vehicle to verify
noise has stopped before returning vehicle to use.
VISUAL INSPECTION BEFORE TESTS
Verify that floor and body plugs are in place and
body components are aligned and sealed. If compo-
nent alignment or sealing is necessary, refer to the
appropriate section of this group for proper proce-
dures.
ROAD TESTING WIND NOISE
(1) Drive the vehicle to verify the general location
of the wind noise.

(2) Apply 50 mm (2 in.) masking tape in 150 mm
(6 in.) lengths along weatherstrips, weld seams or
moldings. After each length is applied, drive the vehi-
cle. If noise goes away after a piece of tape is applied,
remove tape, locate, and repair defect.
POSSIBLE CAUSE OF WIND NOISE
²Moldings standing away from body surface can
catch wind and whistle.
²Gaps in sealed areas behind overhanging body
flanges can cause wind-rushing sounds.
²Misaligned movable components.
²Missing or improperly installed plugs in pillars.
²Weld burn through holes.
STANDARD PROCEDURE
STANDARD PROCEDURE - PLASTIC BODY
PANEL REPAIR
There are many different types of plastics used in
today's automotive environment. We group plastics in
three different categories: Rigid, Semi-Rigid, and
Flexible. Any of these plastics may require the use of
an adhesion promoter for repair. These types of plas-
tic are used extensively on DaimlerChrysler Motors
vehicles. Always follow repair material manufactur-
er's plastic identification and repair procedures.
Rigid Plastics:
Examples of rigid plastic use: Fascias, Hoods,
Doors, and other Body Panels, which include SMC,
ABS, and Polycarbonates.
Semi - Rigid Plastics:
Examples of semi-rigid plastic use: Interior Panels,
Under Hood Panels, and other Body Trim Panels.
Flexible Plastics:
Examples of flexible plastic use: Fascias, Body
Moldings, and upper and lower Fascia Covers.
Repair Procedure:
The repair procedure for all three categories of
plastics is basically the same. The one difference is
the material used for the repair. The materials mustbe specific for each substrate, rigid repair material
for rigid plastic repair, semi-rigid repair material for
semi-rigid plastic repair and flexible repair material
for flexible plastic repair.
Adhesion Promoter / Surface Modifier:
Adhesion Promoters/Surface Modifiers are required
for certain plastics. All three categories may have
plastics that require the use of adhesion promoter/
surface modifiers. Always follow repair material man-
ufacturer's plastic identification and repair
procedures.

When bonding plastic panels, Follow repair mate-
rial manufacturers recommendations. Be sure that
enough adhesive has been applied to allow squeeze
out and to fill the full bond line. Once the pieces
have been brought together, do not move them until
the adhesive is cured. The assembly can be held
together with clamps, rivets, etc. A faster cure can be
obtained by heating with a heat lamp or heat gun.
After the parts have been bonded and have had time
to cure, rough sand the seam and apply the final
adhesive filler to the area being repaired. Smooth the
filler with a spreader, wooden tongue depressor, or
squeegee. For fine texturing, a small amount of
water can be applied to the filler surface while
smoothing. The cured filler can be sanded as neces-
sary and, as a final step, cleanup can be done with
soapy water. Wipe the surface clean with a dry cloth
allowing time for the panel to dry before moving on
with the repair.
PANEL REINFORCEMENT
Structural repair procedures for rigid panels with
large cracks and holes will require a reinforcement
backing. Reinforcements can be made with several
applications of glass cloth saturated with structural
adhesive. Semi-rigid or flexible repair materials
should be used for semi-rigid or flexible backing rein-
forcement (Fig. 2) and (Fig. 3). Open meshed fiber-
glass dry wall tape can be used to form a
reinforcement. The dry wall tape allows the resin to
penetrate through and make a good bond between
the panel and the adhesive. Structurally, the more
dry wall tape used, the stronger the repair.
Another kind of repair that can be done to repair
large cracks and holes is to use a scrap piece of sim-
ilar plastic and bond with structural adhesive. The
reinforcement should cover the entire break and
should have a generous amount of overlap on either
side of the cracked or broken area.
When repairing plastic, the damaged area is first
ªV'dº out, or beveled. Large bonding areas are desir-
able when repairing plastic because small repairs are
less likely to hold permanently. Beveling the area
around a crack at a 20 degree angle will increase the
bonding surface for a repair (Fig. 4). It is recom-
mended that sharp edges be avoided because the
joint may show through after the panel is refinished.²Panel repair for both flexible and rigid panels
are basically the same. The primary difference
between flexible panel repair and rigid panel repair
is in the adhesive materials used (Fig. 5).
²The technician should first decide what needs to
be done when working on any type of body panel.
One should determine if it is possible to return the
damage part to its original strength and appearance
without exceeding the value of the replacement part.
²When plastic repairs are required, it is recom-
mended that the part be left on the vehicle when
every possible. That will save time, and the panel

VISUAL INSPECTION
Composite materials can mask the severity of an
accident. Adhesive bond lines, interior structure of
the doors, and steel structures need to be inspected
carefully to get a true damage assessment. Close
inspection may require partial removal of interior
trim or inner panels.
Identify the type of repair: Puncture or Crack -
Damage that has penetrated completely through the
panel. Damage is confined to one general area; a
panel section is not required. However, a backer
panel, open fiberglass tape, or matted material must
be bonded from behind (Fig. 7) (Fig. 6).
PANEL SURFACE PREPARATION
If a body panel has been punctured, cracked, or
crushed, the damaged area must be removed from
the panel to achieve a successful repair. All spider
web cracks leading away from a damaged area must
be stopped or removed. To stop a running crack in a
panel, drilla6mm(0.250 in.) hole at the end of the
crack farthest away from the damage. If spider web
cracks can not be stopped, the panel would require
replacement. The surfaces around the damaged area
should be stripped of paint and freed from wax andoil. Scuff surfaces around repair area with 360 grit
wet/dry sandpaper, or equivalent, to assure adhesion
of repair materials.
PATCHING PANELS
An panel that has extensive puncture type damage
can be repaired by cutting out the damaged material
(Fig. 7). Use a suitable reciprocating saw or cut off
wheel to remove the section of the panel that is dam-
aged. The piece cut out can be used as a template to
shape the new patch. It is not necessary to have
access to the back of the panel to install a patch.
Bevel edges of cutout at 20 degrees to expose a larger
bonding area on the outer side. This will allow for an
increased reinforcement areas.
PANEL PATCH FABRICATIONS
A patch can be fabricated from any rigid fiberglass
panel that has comparable contour with the repair
area. Lift gates and fenders can be used to supply
patch material. If existing material is not available
or compatible, a patch can be constructed with adhe-
sive and reinforcement mesh (dry wall tape). Perform
the following operation if required:
(1) Cover waxed paper or plastic with adhesive
backed nylon mesh (dry wall tape) larger than the
patch required (Fig. 8).
(2) Tape waxed paper or plastic sheet with mesh to
a surface that has a compatible contour to the repair
area.
(3) Apply a liberal coat of adhesive over the rein-
forcement mesh (Fig. 8). If necessary apply a second
or third coat of adhesive and mesh after firs coat has
cured. The thickness of the patch should be the same
as the repair area.
(4) After patch has cured, peel waxed paper or
plastic from the back of the patch.

(5) If desired, a thin film coat of adhesive can be
applied to the back of the patch to cover mesh for
added strength.
PANEL PATCH INSTALLATION
(1) Make a paper or cardboard pattern the size
and shape of the cutout hole in the panel.
(2) Trim 3 mm (0.125 in.) from edges of pattern so
patch will have a gap between connecting surfaces.
(3) Using the pattern as a guide, cut the patch to
size.
(4) Cut scrap pieces of patch material into 50 mm
(2 in.) squares to use as patch supports to sustain
the patch in the cutout.
(5) Drill 4 mm (0.160 in.) holes 13 mm (0.5 in.) in
from edge of cutout hole (Fig. 7).
(6) Drill 4 mm (0.160 in.) holes 13 mm (0.5 in.)
away from edge of patch across from holes drilled
around cutout.
(7) Drill 3 mm (0.125 in.) holes in the support
squares 13 mm (0.5 in.) from the edge in the center
of one side.
(8) Scuff the backside of the body panel around the
cutout hole with a scuff pad or sandpaper.
(9) Mix enough adhesive to cover one side of all
support squares.
(10) Apply adhesive to cover one side of all support
squares.
(11) Using number 8 sheet metal screws, secure
support squares to back side of body panel with
adhesive sandwiched between the panel and squares
(Fig. 9).(12) Position patch in cutout against support
squares and adjust patch until the gap is equal along
all sides (Fig. 10).
(13) Drill 3 mm (0.125 in.) holes in the support
squares through the pre-drilled holes in the patch.
(14) Apply a coat of adhesive to the exposed ends
of the support squares (Fig. 11).
(15) Install screws to hold the patch to support
squares (Fig. 12). Tighten screws until patch surface
is flush with panel surface.
(16) Allow adhesive to cure, and remove all screws.
(17) Using a 125 mm (5 in.) 24 grit disc grinder,
grind a 50 mm (2 in.) to 75 mm (3 in.) wide and 2
mm (0.080 in.) deep path across the gaps around the
patch (Fig. 13). With compressed air, blow dust from
around patch.
(18) Apply adhesive backed nylon mesh (dry wall
tape) over gaps around patch (Fig. 14).
(19) Mix enough adhesive to cover the entire patch
area.
(20) Apply adhesive over the mesh around patch,
and smooth epoxy with a wide spreader to reduce fin-
ish grinding. Use two to three layers of mesh and
adhesive to create a stronger repair (Fig. 15).
