14. Remove timing belt.
CAUTION:
1. Do not bend or twist the belt, otherwise its core
could be damaged. The belt should not be bent at
a radius less than 30 mm (1.1811 in).
2. Do not allow oil or other chemical substances to
come in contact with the belt. They will shorten
the life.
3. Do not attempt to pry or stretch the belt with a
screw driver or any other tool during installation.
4. Store timing belt in a cool and dark place. Never
expose the belt direct sunlight or heat.

mark on oil pump (1).
Align the mark on the crankshaft timing pulley (3)
with alignment mark (white dotted line) on the tim-
ing belt (4).

2. Align the alignment mark on the RH bank
camshaft drive pulley (2) to the alignment mark of
the cylinder head cover RH (3).
The camshaft pulley is not 1:1 with the camshafts.
It is necessary to rotate the camshaft pulley until
the camshaft lobes are in the position as shown
in the diagram on page 6A±34.
The camshaft pulley alignment mark should also
align with alignment mark on the cylinder head
cover.
It may require up to four revolutions of the
camshaft pulley to achieve alignment of all marks.

3. Align the alignment mark (white line) on the timing
belt (1) with alignment mark on the RH bank
camshaft drive pulley (2) (on the left side as
viewed from the front of the vehicle) and put the

4. Align the alignment mark on the LH bank
camshaft drive pulley (2) to the alignment mark of
the cylinder head cover LH (3).
The camshaft pulley is not 1:1 with the camshafts.
It is necessary to rotate the camshaft pulley until
the camshaft lobes are in the position as shown
in the diagram on page 6A±34.
The camshaft pulley alignment mark should also
align with alignment mark on the cylinder head
cover.
It may require up to four revolutions of the cam-
shaft pulley to achieve alignment of all marks.
5. Align the alignment mark (white line) on the timing
belt (1) with the alignment mark on the LH bank
camshaft drive pulley (2).
When aligning the timing marks, use a wrench to
turn the camshaft drive pulley, then set the timing
mark between timing belt and camshaft drive
pulley and put the timing belt on the camshaft
drive pulley.
Secure the belt with a double clip or equivalent
clip.NOTE: It is recommended for easy installation that the
belt be secured with a double clip or equivalent clips after
it is installed to each pulley.

6. Install crankshaft pulley temporarily and tighten
center bolt by hand (do not use a wrench).
Turn the crankshaft pulley clockwise to give some
belt slack between the crankshaft timing pulley
and the RH bank camshaft drive pulley.
2. Install pusher and tighten bolt to the specified torque.
Torque : 25 N´m (2.5 kg´m/18 lb ft)
1. Install the pusher while pushing the tension pulley
to the belt.
2. Pull out pin from the pusher.
NOTE: When reusing the pusher, press the pusher with
approximately 100Kg to retract the rod, and insert a pin
(1.4 mm (0.055 in) piano wire).
