7) Install in the reverse order of removal.
Tightening torque (Spark plug):
20.6
±2.9 N´m (2.10±0.30 kg-m, 15.19±2.14
ft-lb)
CAUTION:
The above torque should be only applied to
new spark plugs without oil on their threads.
In case their threads are lubricated, the torque
should be reduced by approximately 1/3 of the
specified torque in order to avoid over-stress-
ing.
B: INSPECTION
Check electrodes and inner and outer porcelain of
plugs, noting the type of deposits and the degree
of electrode erosion.

(A) Electrode gap
(B) Carbon accumulation or wear
(C) Cracks
(D) Damage
(E) Damaged gasket
1) Normal
Brown to grayish-tan deposits and slight electrode
wear indicate correct spark plug heat range.
G6M0087
2) Carbon fouled
Dry fluffy carbon deposits on insulator and elec-
trode are mostly caused by slow speed driving in
city, weak ignition, too rich fuel mixture, dirty air
cleaner, etc.
It is advisable to replace with plugs having hotter
heat range.
G6M0088
3) Oil fouled
Wet black deposits show excessive oil entrance
into combustion chamber through worn rings and
pistons or excessive clearance between valve
guides and stems. If same condition remains after
repair, use a hotter plug.
G6M0089
4) Overheating
White or light gray insulator with black or gray
brown spots and bluish burnt electrodes indicate
engine overheating. Moreover, the appearance
results from incorrect ignition timing, loose spark
plugs, wrong selection of fuel, hotter range plug,
etc. It is advisable to replace with plugs having
colder heat range.

A: ADJUSTMENT
1. HEADLIGHT AIMING
NOTE:
As this headlight is the ªVISUAL AIMING TYPEº, it
is possible to adjust aiming only in the vertical
direction. It cannot be adjusted in the horizontal
direction.
CAUTION:
Turn off the light before adjusting headlight
aiming. If the light is necessary to check
aiming, do not turn on for more than two min-
utes.
NOTE:
Before checking the headlight aiming, be sure of
the following:
IThe area around the headlight has not sustained
any accident, damage or other type of deformation.
IVehicle is parked on level ground.
IThe inflation pressure of tires is correct.
IVehicle's gas tank is fully charged.
IBounce the vehicle several times to normalize
the suspension.
IMake certain that someone is seated in the driv-
er's seat.
1) Place a cloth over the headlight that does not
