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.

body construction which
incorporates integral front
and rear frame side rails. FLOOR PAN INSULATORS
Consideration must be given when checking
underbody dimensions. The engine front suspension
lower control arms are supported by a cross member.
The cross member, in turn, is bolted to the body at six
locations
-- three on each side of the engine front
compartment lower rails. Mounting provisions for the
front suspension system are shared by chassis
components (suspension lower control arms and cross
member) and body components (engine compartment
side panels). The suspension strut towers must be
dimensionally correct in relation to the remainder of
the underbody in order to maintain specified
suspension strut and
castedcamber angles.
Since the individual underbody components also
contribute directly to the overall strength of the body,
it is essential that proper welding techniques be
observed during service repair operations. The
underbody components should be properly sealed and
rustproofed whenever body repair operations destroy
or damage the original sealing and rustproofing. When
rustproofing critical underbody components, it is
essential that a good quality type of air dry primer be
used (such as corrosion resistant chromate or
equivalent material). It is not advisable to use
combination type primer-surfacers.
ALIGNMENT CHECKING
An accurate method of determining the
alignment of the underbody utilizes a measuring tram
gage. The tram gage set required to perform the
recommended measuring checks must include a
vertical pointer capable of reaching 914 mm (36").
Two types of measurements can be made with
a
tram gage: direct point-to-point measurements and
measurements calculated on a horizontal
vlane (datum
line) parallel to the underbody. In the
latter case, the
vertical pointers must be set as specified for each point
to be measured (Fig. 3-1).
Point-to-point measurements are generally taken
only on engine compartment components (Fig. 3-2)
and simply require the vertical pointers to be equally
set.
Figure #3-3 describes the alphabetically
identified points of measurement. Figure 3-4 provides Floor
pan insulators have been designed for the
higher floor pan temperatures that result from the use
of the catalytic converter in the exhaust system.
Therefore, when servicing a vehicle in the field, it is
essential that any insulators that may have been
disturbed or removed be reinstalled in the original
sequence and location. Also, if it becomes necessary to
replace an insulator, the material specified for that
particular location on the floor pan must be used. The
types of materials are listed below. Items 1 and
2 are
rolled stock and are ordered by linear foot and cut to
fit.
1. Insulator floor pan
(cerra blanket thermal) -
consists of 10 mm (3/8") thick aluminum silica
(type 1).
2. Insulator floor pan (amberlite) - consists of 10
mm
(3/8") thick resinated fibers (type 2).
3. Insulator floor pan sheet (phenolic bonded fiber
glass)
305 mm x 457 mm (12" x 18") cut to size,
(type 3).
All of the above materials must meet
Motor Vehicle Safety Standard No. 302 for
flammability.
When servicing or replacing interior insulators,
the following instructions must be observed:
1. Insulators must be installed in the original
position and sequence. Pieces should be butted
together in order to avoid gapping or
overlapping.
2. If it is necessary to replace an insulator, the
specified material must be used.
3. Use original
part to determine the amount of
replacement material required and as a template
for cutting and fitting the new piece to the floor
pan.
4. When installing insulator, do not enlarge cutouts
or holes that are used for the attachment of
interior components such as seats or seat belts.
5. Cross body harnesses for interior components
such as power seats, lap belt warning light and
buzzer or rear speakers must be routed over the
floor pan insulators in the original location and
clipped in place.
