INSTALLATION SERVICE POINTS
>>A<< IGNITION COIL BOOT INSTALLA-
TION

CAUTION

• When the ignition coil boot is not installed as

indicated, realize that it would be possibly the
causes of the malfunctions which lead to an
inappropriate ignition coil operation, a dam-
aged ignition coil, a high voltage leakage
toward the outside and water immersion into
the hole.

• White powders are applied to the fitting area

of the spark plug on the ignition coil boot in
order to prevent the fitting area from baking
onto the spark plug. Do not touch or clean
them.

1. Confirm the spring is attached to the new ignition

coil boot inside.

2. Push and install the new ignition coil boot into the

ignition coil without a clearance, turning the fitting
area twice or three times.

3. After the installation, turn the ignition coil boot so

that the air bleeding hole can be in position
indicated in the illustration.

REMOVAL SERVICE POINTS
<<A>> PLUG CAP REMOVAL

Loosen the plug cap, holding the hexagonal portion
of the camshaft with a wrench.

<<B>> TIMING BELT REMOVAL

1. If the timing belt is to be reused, make an arrow

mark with something like chalk on the back of the
belt indicating the direction of rotation so it may be
reinstalled in the same direction.

CAUTION

Never remove the timing belt with any piston at
the top dead centre (TDC). If a piston is at TDC,
the exhaust valves of the cylinder are pushed by
the exhaust cams, compressing the valve
springs. If the belt is removed under this condi-
tion, the sprocket will be turned in the reverse
direction by the force of the springs, incurring
risk of injury.
2. Set the timing mark of the exhaust camshaft

sprocket to a point about one tooth before the
TDC of the No.1 cylinder piston on compression
stroke.

3. Loosen the lock nut of the tensioner pulley, then

remove the timing belt.
