O 
Fitting the O-ring/oil feeder control valve
Caution
1. Do not re-use O-rings.
2. When fitting O-rings, first wind some non-adhesive tape
(seal tape etc) around the oil channel of the oil feeder
control valve, in order to prevent damage to the O-ring.
If the O-ring touches the oil it could start an oil leak.
1. Apply engine oil to the O-ring on the oil feeder control valve.
2. Fit the oil feeder control valve to the cylinder head.
3. Tighten the mounting bolts for the oil feeder control valve to the
specified torque.
Tightening torque: 11 ± 1 N•m

2.
(1) As shown in the diagram, apply a force of about 100N to the
middle of the belt between the sprockets (indicated by the
arrow), and check that the amount of give is as specified.
Specified values:
5~7mm
5~7mm
(2) If the specified values are not met, readjust the tension of the
belt.
3.
(1) Connect the special belt tension meter set (MB991668) to the
MUT-II/III.
(2) Connect the special battery harness (MB991704) to the MUT-
II/III, and also connect it to the batteries.
(3) Give the crankshaft two turns in a clockwise direction, and check
that the No.1 cylinder is in the top dead centre position, and that
the timing marks on each sprocket are aligned.
(4) Select the “belt tension measurement” option from the display
on the MUT-II/III.
(5) As shown in the diagram hold the special belt tension meter set
(MB991668) in the middle of the belt between the sprockets
(indicated by the arrow), 10~20mm away from the outer side of
the belt and vertically to the belt (not leaning more than ±15°
away from vertical).
(6) As shown in the diagram, lightly pull the middle of the belt
between the sprockets (indicated by the arrow) using fingertips
and check that the vibration frequency of the belt is within the
limits specified.
Specified values: 76 ~ 92 Hz
Caution
(1) The meter may give an incorrect reading if the
microphone is affected by a strong wind, or if there are
loud noises nearby, while testing is taking place.
(2) The meter may give an incorrect reading if testing is
performed while the microphone is touching the belt.
(7) If the specified values are not met, readjust the tension of the
belt.

5. Using the special wrench for the tensioner pulley socket
(MD998767) or a torque wrench, apply tension torque (3.5 N·m)
to the timing belt in the direction shown in the diagram, and
tighten the mounting bolt for the tensioner pulley to the specified
torque.
Tightening torque: 48 ± 5 N·m
Caution
When tightening the installed bolt, take care that the
tensioner pulley does not turn around with it. If the pulley
does turn around with the bolt, the tension of the belt will
become too strong.
6. Remove the wire or pin which had been inserted when the auto-
tensioner was fitted.
7. Remove by hand the special adjusting bolt (MD998738) which
had been fitted in step 1.
8. Turn the crankshaft two complete turns in a clockwise direction,
and leave it for about 15 minutes.
9. Reinsert the wire or pin which had been removed in step 6, and
check that it can be easily pulled out again.
If the wire or pin can be easily pulled out the tension of the
timing belt is just right, so the wire or pin should be removed
completely. At this point check that the auto-tensioner rod is not
projecting more than the amount specified.
Specified projection (A): 3.8 ~ 4.5 mm
10. If the wire or pin cannot be easily pulled out, repeat steps 1 to 8
until the tension of the timing belt is just right.
11.Recheck that the timing marks on all of the sprockets are in line.
Caution
If the crankshaft bolt is turned in an anti-clockwise
direction, the tightening torque of the crankshaft bolt must
be checked, and if it is loose, it must be retightened.

Inter-cooler water spray circuit systemProbable causes of the malfunction
•If the inter-cooler water spray switch (manual) is turned ON, the inter-cooler
water spray manual ‘ON’ signal will be input in the engine ECU. When this
signal is received, the engine ECU will turn the inter-cooler water spray relay
ON, and will start the inter-cooler water spray motor. Water will be sprayed
into the inter-cooler to cool intake air, and filling efficiency will improve.
•If the inter-cooler water spray switch (auto) is turned ON, the inter-cooler
water spray auto ‘ON’ signal will be input in the engine ECU. When this
signal is received the engine ECU will intermittently run at a high load, it will
turn the inter-cooler water spray relay ON, and it will start the inter-cooler
water spray motor. Water will be sprayed into the inter-cooler to cool intake
air, and filling efficiency will improve.•Malfunction of the inter-cooler water
spray switch.
•Malfunction of the inter-cooler water
spray relay.
•Malfunction of the inter-cooler water
spray motor.
•Circuit break, short circuit or a faulty
