Fitting the camshaft sprocket (inlet side)
1. Apply engine oil to the edges of the camshaft, and to the parts
of the camshaft sprocket which will make contact with the
camshaft.
2. Match up the camshaft dowel pins with the dowel pin holes in
the camshaft sprocket, and fit the camshaft into the camshaft
sprocket.
3. Hold the hexagonal part of the camshaft with a wrench, and
check that the camshaft sprocket cannot be twisted.
Note
This operation is necessary because it is impossible to check by
looking whether the camshaft dowel pins are inserted into the
dowel pin holes in the camshaft sprocket.
4. Apply engine oil to the screw thread and the underside of the
camshaft sprocket mounting bolt, and in the same way as when
the camshaft sprocket was removed, hold the camshaft in place
using a wrench and tighten the bolt to the specified torque.
Tightening torque: 65 ± 5 N•m
I
Fitting the camshaft sprocket (exhaust side)
In the same way as when the camshaft sprocket was removed,
hold the hexagonal part of the camshaft with a wrench and
tighten the bolt to the specified torque.
Tightening torque: 89 ± 9 N•m
J
Fitting the camshaft position sensor support
1. Remove any sealant from the camshaft position sensor support.
2. As shown in the diagram, apply sealant to the flange of the
camshaft position sensor support, and then fit it to the cylinder
head.
Semi-dry sealant: Three bond 1207F
3. Tighten the mounting bolts for the camshaft position sensor
support to the specified torque.
Tightening torque: 14 ± 1 N•m

Removal guidelines
A
Removing the timing belt
1. Turn the crankshaft in a clockwise direction, and match up all
the timing marks until the No.1 cylinder is in the compressor top
dead centre position.
Caution
Turn the crankshaft in the normal way.
2. Remove the rubber plug from the rear cover of the timing belt,
and prepare the special tool for adjusting bolts (MD998738).

GENERAL
Servicing guidelines have been changed because of the changes listed below.
•Avariable valve timing control system (V.V.T.) has been adopted. Because of this, an oil feeder control valve and an intake
cam position sensor have been added.
•Amanifold absolute pressure (MAP) sensor has been added.
•An air temperature sensor has been added.

If a MUT-III main harness A is connected to
