ADHESIVE BODY SlBE MOLDING
The body side moldings are attached to the body
panels with adhesive tape. To insure a good molding
replacement (new or old moldings), the panel surface
should be warm (21°C to 32°C or 70°F to
90°F), clean
and free of any wax or oily film. Two methods are listed
to attach loose molding ends and completely removed
m~ldings.
Molding End Loose
1. Wash affected area with soap and water and wipe
dry. Wipe panel and adhesive side of molding
with a clean rag using oil-free naphtha or alcohol.
If molding has pulled loose from adhesive
backing (tape remains on body panel), do not
remove tape from body. Clean back of molding
and tape on body with oil-free naphtha or alcohol
and proceed with step 3.
2. If needed, apply a length of masking tape as a
molding guide.
A straightedge may also be used
in most cases.
3. Apply adhesive to back of molding and press in
place. If Loctite
414 adhesive (part no. 1052283)
or equivalent is used, apply constant pressure to
molding for 30 seconds or until a firm bond has
been made.
Molding Completely Removed
1.
Wash affected panel area with soap and water
and wipe dry. Remove all traces of adhesive from
body panel and back of molding using oil-free
naphtha or alcohol.
2. Mark proper position of molding with a length of
masking tape. Use adjacent moldings as a guide,
if applicable (Fig. 6).
3. If body is below 21°C (70°F) due to shop
temperature or outside temperature, warm body
panel with heat lamp or heat gun while
proceeding with step
4.
4. Apply a double-coated acrylic foam tape such as
3M Super Automotive Attachment Tape (part
no. 06380 which has a white backing or part no.
06379 which has a black backing) or equivalent
to the molding.
5. Align molding to tape guideline and press firmly
in place.
WATERLEAK DIAGNOSIS AND REPAIR
GM vehicles are designed to operate under
normal environmental conditions. The design criteria
for sealing materials and components takes into
consideration the sealing forces required to withstand
the natural elements. These specifications do not, and
cannot, take into consideration all artificial conditions
such as may be encountered in some high pressure car
washes.
The watertest procedure has been correlated to
the natural elements and will determine the ability of
a car to perform under normal operating conditions.
Repairing body waterleaks is a problem of proper
testing, diagnosis and repair through adjustment of
misaligned components and/or application of proven
repair materials. The first step in waterleak diagnosis
is finding the conditions under which the leak occurs.
For example, leak noticed only when parked on an
inclined drive or water in spare tire compartment.
If the general leak area can be found, the exact
entry point can be quickly isolated by use of a localized
test such as a water hose or air hose. If the leak source
is not obvious, the generalized testing method using
watertest equipment such as the watertest stands
shown in Figures
7 and 8 should be used. It may be
necessary to remove some interior trim panels or
components to locate and confirm repairs.
GENERALIZED TESTING
Specifications for construction of the watertest
stand are shown in Figure 9.
If the specified water pressure of 155
kPa (22 psi)
cannot be obtained because of a local situation, both
test stands may be moved toward body until water
spray overlap can be obtained.
LOCALIZED TEST lNG (SPOT TEST)
Localized testing may be made with either water
or air. Begin test at the base of the suspected area and
continue up slowly until the leak is located.

FLEXIBLE EXTERIOR PLASTIC PARTS
REPAIR AND
REFlNlSHlNG (EXCEPT
E/P OR TPO)
Soft plastic parts used for exterior or cosmetic
application are compounded of resins that have flexible
characteristics in order to absorb minor impact
without sustaining damage. Typical examples include
bumpers, front end fascia or side panels such as
fenders. These parts are generally fabricated of
thermosetting plastics which, when cured, cannot be
melted with application of heat such as through hot air
welding. However, if the impact force is great enough
to create damage, thermoset plastics can be
successfully repaired with structural adhesives.
Briefly, the repair system amounts to a filling
and, where necessary, a reinforcing operation. After
curing, the patch is dressed to conform to the
surrounding contour.
Following are typical damage conditions and
respective repair procedures:
1. Gouge or puncture repair
a. Clean the repair area with a wax, grease and
silicone-removing solvent applied with a
water-dampened cloth. Wipe dry. With a
random orbit sander fitted with a
# 180 grit
disc, remove the paint film in and
surrounding the area to be filled. The repair
material should
not overlap the painted
surface (Fig. 24).
Fig. 24-Removing Paint Surrounding Damage
b. Use a clean 2" or 3" # 50 grit disc to enlarge
the gouge or puncture in order to ensure
removal of grease, oil or dirt from the area
to be contacted by the repair material. This
action should also create at least a 25 mm
(1
") taper around the damage for extended
contact between the repair material and
substrate. Remove all dust and loose
particles from the repair area (Fig. 25).
Aluminum
Autobody Repair Tape (3M
#06935, &to6936 or equivalent) can be
used on the back side of a puncture
to
support the repair material (Fig. 26).

2H-4 STATIONARY GLASS - F STYLE
7. Watertest car at once using soft spray. Use warm
or hot water if available. Do not direct hard
stream of water at fresh adhesive material. If any
leaks are found, paddle in extra adhesive at leak
point using a small disposable brush or
flat-bladed tool. Water applied on top of urethane
adhesive, either during watertest or as a separate
operation, will speed up the cure of the urethane.
8. Install windshield reveal molding.
9. Install
all other previously removed parts and
clean up.
10. On windshield installations, car must remain at
normal room temperature for six hours to
complete proper cure of adhesive.
Extended Method
It will be necessary to use extended installation
method if prior service installation was made with
butyl tape or if urethane material remaining in window
opening after window removal is damaged, or must be
removed to permit refinishing of window opening.
Spacers are used to maintain the dimensions of
the windshield stand off from the pinchweld flange.
The spacers are specific to certain styles and can be
found in the service parts manual. Spacers should be
reused or replaced before reinstallation of windshield
(Fig. 6).
Fig. 6 - Glass Spacer Location
Using a sharp scraper or chisel, remove the old
adhesive material from window opening. On butyl tape
installations or installations of unknown material, it
will be necessary to remove all traces of the material.
On urethane installations, it is not necessary that all
traces of material be removed, but there should not be
any mounds or loose pieces left.
If refinishing or painting operations are required,
or painted surface is exposed during removal of
material, black primer should be applied to exposed
area.
Install or Connect
1. Locate glass stops in their original positions.
2. With aid of helper, lift glass into window opening.
The windshield glass can be positioned without
aid of carrying devices as shown in Figure 5. Place window
in vertical position and support it
on lower glass supports. While one man holds
glass in position, second man can reach one arm
around body pillar and support glass while other
man assumes the same position.
With glass positioned in opening, check
relationship of glass to pinchweld flange around
entire perimeter. The opening between glass and
pinchweld flange should be equal for installation
of the vinyl reveal molding. The opening at the
top of windshield may be corrected by
repositioning lower glass supports.
After final adjustments have been made and glass
is in proper position, apply pieces of masking tape
over edges of glass and body, slit tape at edge of
glass. Tape on glass can be aligned with tape on
body to guide glass into opening during
installation. Remove glass from opening.
For extended method, enlarge nozzle opening by
removing material as indicated in Figure
4.
Clean
Surface of glass to which bead of adhesive
material will be applied (around edge of inside
surface of glass) by wiping with a clean, alcohol
dampened cloth. Allow to air dry.
Two primers are provided in Urethane Adhesive
Kit No. 9636067 or equivalent. The clear primer
is used on the glass prior to the black primer and
is applied to the entire perimeter of glass edge and
6 mm
(1/4") inboard on inner surface. Allow
primer to dry for five minutes. Apply black
primer to any portion of glass opening that
required refinishing and painting operations, or
any portion that was cleaned of former adhesive
enough to expose the painted surface. Allow
primer to dry for five minutes.
With caulking gun and nozzle positioned as
illustrated in Figure 4, carefully apply smooth
continuous bead of adhesive 10 mm
(3/8") high
by 5 mm
(3/16") wide at base completely around
inside edge of glass. Make sure bead of adhesive
is tipped slightly inboard.
With glass centered at opening, place glass on
lower supports. Use tape guides previously
applied to place glass in proper position. On
windshield installation, guide lower outer surface
of glass along rear edge of front fenders to avoid
smearing fresh adhesive on instrument panel
(Fig. 5). Make certain glass is aligned properly to
tape guides on pillars, and positioned on lower
metal supports. Apply light hand pressure to
wet-out adhesive and obtain bond to body
opening. Using small, disposable brush or
flat-bladed tool, paddle material around edge of
glass to ensure watertight seal. If necessary,
paddle additional material to fill voids in seal.
Watertest at once using soft spray. Use warm or
hot water if available. Do not direct stream of
water at fresh adhesive. Allow water to spill over
edges of glass. If waterleak is encountered, use
flat-bladed tool to work in additional adhesive
material at leak point.

RECLINING SEATBACK
All styles have bucket seats with a tubular frame
design
seatback (Fig. 15) and a recliner control
mechanism. The tubular frame
seatback has a single
side, recliner control mechanism. This recliner
mechanism, which is mounted on the outboard side of
the seat, is the sole control of the
seatback angle. The
inner hinge arm attaching bolt acts only as a point of
rotation for the seatback. The inertia lock is an integral
part of the recliner control mechanism (Fig.
16).
To recline the seatback, rearward pressure must
be applied to the
seatback before lifting the recliner
release handle. When pressure is applied against the
seatback, the lockout lever tab disengages from the cam
plate tab. Then the release handle can be moved,
allowing the
seatback to move rearward. Releasing the
handle will allow the cam plate to move
counterclockwise and cause the sector lock teeth to
engage the upper hinge arm, locking the
seatback in the
desired reclined position. To return the
seatback to an
upright position, raise the recliner release handle.
