WATER LEAKS
Water leaks can be caused by poor sealing, improper
body component alignment, body seam porosity, miss-
ing plugs, or blocked drain holes. Centrifugal and
gravitational force can cause water to drip from an
area somewhat distant from the actual leak point,
making leak detection difficult. All body sealing points
should be water tight in normal wet driving conditions.
Water flowing downward from the front of the vehicle
should not enter the passenger or luggage compart-
ment. Moving sealing surfaces will not always seal
water tight under all conditions. At times, side glass,
door, or convertible top seals will allow water to enter
the passenger compartment during high pressure
washing or hard driving rain (severe) conditions. Over
compensating on door, glass, or top adjustments to stop
a water leak that occurs under severe conditions, can
cause premature seal wear and excessive closing or
latching effort. After a repair procedure has been
performed, water test vehicle to verify leak has stopped
before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK
TESTS
Verify that floor and body plugs are in place, body
drains are clear and body components are aligned and
sealed. If component alignment or sealing is necessary,
refer to the appropriate section of this group for proper
procedures.
WATER LEAK TESTS
WARNING: DO NOT USE ELECTRIC SHOP LIGHTS
OR TOOLS IN WATER TEST AREA, PERSONAL IN-
JURY CAN RESULT.
When a determination has been made on the condi-
tions that a water leak occurs, simulate the conditions
as closely as possible.
• If a leak occurs when the car is parked in a steady
light rain, flood the leak area with a open ended garden
hose.
• If a leak occurs at highway speeds in a steady rain,
test the leak area with a stream or fan spray of water
from a garden hose with an adjustable nozzle. Direct
the spray in the direction comparable to actual condi-
tions.
• If a leak seems to occur only when the vehicle is
parked on an incline, hoist the end or side of the vehicle
to simulate this condition before water testing. This
method can also 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 vehicle. For hoisting recommendations refer
to Group 0, Lubrication and Maintenance, General
Information section.
WATER LEAK DETECTION
To detect a water leak point of entry, perform a water
test and watch for water tracks or droplets forming on
the inside if the vehicle. If necessary remove interior
trim covers or panels to gain visual access to the leak
area. If the hose can not be positioned without being
held, have someone help perform the water test.
Some water leaks must be tested for a considerable
length of time to become apparent. When a leak ap-
pears, determine the highest point of the water track or
drop. The highest point usually will indicate the point
of entry. After leak point has been determined, repair
the leak and water test to verify that leak has stopped.
Locating the entry point of water that is leaking into
a cavity between panels can be difficult. The trapped
water splashes or runs from the cavity it is dammed up
in, often at a distance from the entry point. Most water
leaks of this type become apparent after accelerating,
stopping, turning, or when on a incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use a
suitable mirror to gain visual access. A mirror can also
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 vehicle in
a brightly light area. From inside the darkened lug-
gage compartment inspect around seals and body
seams. If necessary, have a helper direct a drop light
over the suspected leak areas around the lug-

gage compartment. If light is visible through a nor-
mally sealed location, water could enter through the
opening.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compartment
can not be detected by water testing, pressurize the
passenger compartment and soap test exterior of the
vehicle. To pressurize the passenger compartment,
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 assure adequate voltage to the blower. With
interior pressurized, apply dish detergent solution 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.
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 air tight in normal
driving conditions. Moving sealing surfaces will not
always seal air tight under all conditions. At times,
side glass, door, or convertible top seals will allow wind
noise to be noticed in the passenger compartment
during high cross-winds. Over compensating on door,
glass, or top adjustments to stop wind noise that occurs
under severe conditions, can cause premature seal
wear and excessive closing or latching effort. After a
repair procedure has been performed, test vehicle to
verify leak has stopped before returning vehicle to use.
Wind noise can also be caused by improperly fitted
exterior mouldings or body ornamentation. Loose
mouldings can flutter, creating a buzzing or chattering
noise. An open cavity or protruding edge can create
whistling or howling noise. Inspect the exterior of the
vehicle to verify that these conditions do not exist.
VISUAL INSPECTION BEFORE TESTS
Verify that floor and body plugs are in place, body
drains are clear and body components are aligned and
sealed. If component alignment or sealing is necessary,
refer to the appropriate section of this group for proper
procedures.
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 moul-
dings. After each length is applied drive vehicle. If
noise goes away after a piece of tape is applied, remove
tape, locate and repair defect.
POSSIBLE CAUSE OF WIND NOISE
• Mouldings standing away from body surface can
catch wind and whistle.
• Gaps in sealed areas behind overhanging body
flanges can cause wind rushing sounds.
• Misaligned movable components.
• Missing or improperly installed plugs in pillars.
• Weld burn through holes.

PAINT
INTRODUCTION
A paint code is provided on the body code plate
located in the engine compartment. Refer to the Intro-
duction section at the front of this manual for body code
plate description. The color names provided in the
Paint and Trim Code Description chart are the color
names used on most repair product containers. The
color names in the new vehicle ordering guides vary
depending on car line but use the same color code.
BASE COAT/CLEAR COAT FINISH
On most vehicles a two part paint application (base
coat/clear coat) is used. Color paint that is applied to
primer is called base coat. The clear coat protects the
base coat from ultra violet light and provides a durable
high gloss finish.
WET SANDING,BUFFING AND POLISHING
Minor acid etching, orange peel or smudging in clear
coat can be reduced with light wet sanding, hand
buffing and polishing. If the finish has been wet sanded
in the past, it can not be repeated. Wet sanding
operation should be performed by a trained automotive
painter.
CAUTION: Do not remove clear coat finish, if
equipped. Base coat paint must retain clear coat to
shine.
PAINTED SURFACE TOUCH-UP
When a painted metal surface has been scratched or
chipped, it should be touched-up as soon as possible to
avoid corrosion. For best results, use Mopar
tScratch
Filler/Primer, Touch-Up Paints and Clear Top Coat.
Refer to Introduction group of this manual for Body
Code Plate information.
TOUCH-UP PROCEDURE
(1) Scrape loose paint and corrosion from inside
scratch or chip.
(2) Clean affected area with Mopar
t Tar/Road Oil
Remover and allow to dry.
(3) Fill the inside of the scratch or chip with a coat of
filler/primer. Do not overlap primer onto good surface
finish. The applicator brush should be wet enough to
puddle fill the defect without running. Do not stroke
brush applicator on body surface. Allow the filler/
primer to dry hard.
(4) Cover the filler/primer with color touch-up paint.
Do not overlap touch-up color onto the original color
coat around the scratch or chip. Butt the new color to
the original color if possible. Do not stroke applicator
brush on body surface. Allow touch-up paint to dry
hard.
(5) On vehicles without clear coat, the touch-up color
can be lightly (600 grit) wet sanded and polished with
rubbing compound.
(6) On vehicles with clear coat, Apply clear top coat
to touch-up paint with the same technique as described
in step 4. Allow clear top coat to dry hard. If desired,
step 5 can be performed on clear top coat.
