ALL A
TION/ADJUSTMENT
The engine speed sensor uses a slotted hole on one
side (Fig. 10) to adjust its depth. A brass (non-mag
netic) feeler gauge must be used to adjust the sensor.

Sensor—Installation
Sensor-to-vibration damper air gap is: 1.25 MM
(.049 in.) minimum to 1.30 MM (.051 in.) maximum.
(2) Position speed sensor, its two mounting spacers
and two mounting nuts to the engine. Install mount
ing nuts finger tight.
(3) Route sensor wiring harness behind engine pul
leys.
Install and tighten wiring harness clip bolts. (4) Place the feeler gauge between the sensor and
the vibration dampener. (5) Gently seat (push down) the sensor until it con
tacts the feeler gauge. Be sure the sensor is not
near either of the notches (Fig. 9) on the vibra
tion damper. If sensor is adjusted at or near
these notches, it will be damaged when engine is started.
(6) Tighten sensor mounting nuts to 24 N#m (18 ft.
lbs.) torque.
(7) Remove feeler gauge.

INFLATION
PRESSURES
Under inflation (Fig. 2) causes rapid shoulder wear
and tire flexing. Over inflation (Fig. 3) causes rapid center wear
and loss of the tire's ability to cushion shocks. Improper inflation can cause;
• Uneven wear patterns
• Reduced tread life
• Reduced fuel economy
• Unsatisfactory ride
• Cause the vehicle to drift Refer to the Owner's Manual for information re
garding proper tire inflation pressure. This pressure has been carefully selected to provide
for safe vehicle operation. Tire pressure should be

pressure. Cold inflation pres sure is obtained after the vehicle has not been
operated for at least 3 hours. Tire inflation pressures may increase from 2 to 6 pounds per square inch (psi) during operation. Do not reduce this normal
pressure build-up.

not be driven at continuous speeds above 75 mph (120 km/h).

REMOVAL
(1) Remove exterior trim as necessary to clear cap
tured edges of the tape stripe being removed
(2) Remove tape stripe using a suitable heat gun
or lamp. This will soften the adhesive backing.
(3) Clean adhesive residue from body finish using
a suitable adhesive remover.
INSTALLATION
INSTALLATION EQUIPMENT
• Bucket filled with a mild dish soap solution.
• Lint free applicator cloth or sponge. • Body putty applicator squeegee.
• Heat gun or sun lamp.
• Razor knife.
The painted surface of the body panel to be covered
by a tape stripe must be smooth and completely cured before the stripe can be applied. If the painted surface is not smooth, wet sand with 600 grit wet/dry
sand paper until surface is smooth.
Ripples and feather edges will read through the
stripe if surface is not properly prepared. (1) With backing still in place, position stripe
across panel to receive the stripe. Apply masking at
top of stripe to hold it in position. (2) Mark outside edge of panel on stripe with
grease pencil. (3) Trim stripe to within 17 mm (0.750 in.) of out
line marks.
(4) Spread stripe across a smooth flat work surface,
stripe side down. (5) Peel paper backing away from stripe exposing
adhesive backing of stripe.
(6) Apply soap solution liberally to adhesive back
ing of stripe. (7) Apply soap solution to body panel surface.
(8) Place stripe into position on body panel.
Smooth out wrinkles by pulling lightly on edges of
tape stripe until it lays flat on panel surface. (9) Push air pockets from under tape stripe to the
perimeter of the panel from the center of the tape stripe out. (10) Remove air bubbles from under tape stripe us
ing a body putty squeegee (Fig 34).
CAUTION:
Do nut cut

(11) Trim tape stripe to size using a razor knife.
Leave at least 13 mm (0.5 in.) for edges of doors and openings.
CAUTION;
Do not overheat

(12) Apply heat to tape stripe to evaporate residual
moisture from edges of tape stripe. This will also al
low tape stripe to be stretched into concave surfaces.
(13) Edge turn tape stripe around doors or fenders
(Fig 35). (14) Install exterior trim if necessary. Small air or
water bubbles under tape stripe can be pierced with a pin and smoothed out.
