GLASS AND MIRRORS 9L – 17

INSIDE REARVIEW MIRROR
The inside rearview mirror is attached to a support which
is secured to the windshield glass. The support is installed
by the glass supplier using a plastic–polyvinyl butyl adhe-
sive.
Service replacement windshield glass has the mirror sup-
port bonded to the glass assembly. In order to install a de-
tached mirror support or to install a new part, the following
items will be needed:
S Loctite® Minute–Bond Adhesive.
S Original or replacement mirror support.
S Wax marking pencil or crayon.
S Rubbing alcohol.
S Clean paper towel.
S Fine grit sandpaper (grit #320 or #360).
S 2 mm allen wrench.
Installation Procedure
1. Measure the distance from the headliner to the bot-
tom of the location where the mirror support will be
mounted on the windshield.
2. Mark this position on the outside of the glass with a
wax pencil or crayon. Draw a large diameter circle
around the mirror support location on the outside of
the glass.
3. Clean the inside surface of the glass with a domes-
tic scouring cleanser, a glass cleaning solution, or a
polishing compound and paper towels. Rub the
glass until the area is completely dry. When the
area is dry, clean the area with an alcohol–satu-
rated paper towel in order to remove any traces of
the scouring powder or the glass cleaning solution.
4. If the mirror support is new, clean the bonding sur-
face with fine grit sandpaper #320 or #360. If the
original mirror support is being used, all traces of
factory installed adhesive must be removed prior to
reinstallation.
5. Wipe the sanded mirror support with a clean paper
towel saturated with rubbing alcohol. Allow the sup-
port to dry.
6. Follow the adhesive kit manufacturer’s directions
for adhesive application and mirror support prepa-
ration before installing the mirror support to the
glass.
7. Position the mirror support to its premarked posi-
tion. Use steady pressure and press the support
against the glass for 30 to 60 seconds.
8. After 5 minutes, remove the excess adhesive with
an alcohol–moistened towel or a glass–cleaning
solution.
9. Install the inside rearview mirror to the mirror sup-
port with the mounting screw.
Tighten
Tighten the rearview mirror mounting bolt to 1.2 NSm
(11 lb–in).

ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram gauge
set used to perform the recommended measuring checks
must include a vertical pointer able to reach 457 mm (18
inches).
Two types of measurements can be made with a tram
gauge: direct point–to–point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point–to–point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical pointers
to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions–to–gauge holes are measured to the center
of the holes and flush to the adjacent surface metal unless
otherwise specified. It is recommended that the diagonal
dimensions to the cross–body be checked on both sides
in order to verify the dimensional accuracy of the vehicle
underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the higher
floor pan temperatures that result from the use of the cata-
lytic converter in the exhaust system. Therefore, when
servicing a vehicle, it is essential that any insulators that
may have been disturbed or removed be reinstalled in the
original sequence and location. Also, if an insulator needs
to be replaced, use only the insulation specified for that
location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.
S Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.
S If it is necessary to replace an insulator, use only
the specified insulation.
S Use the 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.
S When installing the insulator, do not enlarge any
cutouts or holes that are used for the attachment of
interior parts such as the instrument panel or the
floor console.
S Route the cross–body harness for interior parts
over the floor pan insulators. Clip it in the original
location.
S Do not apply spray–on deadeners or trim adhesives
to the top of the floor pan at the area directly over
the catalytic converter or the muffler.

GENERAL DESCRIPTION
AND SYSTEM OPERATION
GENERAL BODY CONSTRUCTION
This vehicle is constructed with a unitized body which in-
corporates integral front and rear frame side rails.
The front suspension lower control arms are bolted to and
retained by supports, one each on the right and left sides.
The front suspension lower control arm supports are at-
tached to the underbody with three bolts at two locations.
The engine is bolted to the integral front side rails. The
suspension strut towers must be dimensionally correct in
relation to the remainder of the underbody in order to main-
tain specified suspension strut and caster/ camber angles.Since the individual underbody parts contribute directly to
the overall strength of the body, it is essential to observe
proper welding techniques during service repair opera-
tions. The underbody parts should be properly sealed and
rustproofed whenever body repair operations destroy or
damage the original sealing and rustproofing. When rust-
proofing critical underbody parts, use a good–quality type
of air–dry primer, such as a corrosion–resistant chromate
or an equivalent material. Combination–type primer/sur-
facers are not recommended.
ENGINE UNDER COVERS
The engine under covers are molded pieces of plastic that
serve as shields for the underside of the engine. The cov-
ers help protect the engine from small rocks, gravel and
other objects that would otherwise come into contact with
the engine during normal driving conditions.
