(1) Turn the two sprockets so that their dowel
pind arti
located on top. Then, align the timing marks facing each
-
*other with the top surface of the cylinder head. When,
you let go of the exhaust camshaft sprocket, it will
rotate one tooth in the counterclockwise direction. This
should be taken into account when installing the timing
belt on the sprockets.
NOTE
The same camshaft sprocket is used for the intake andexhaust camshafts and is provided with two timing
marks. When the sprocket is mounted on the exhaust
camshaft, use the timing mark on the right with the
*dowel pin hole on top. For the intake camshaft
-sprocket, use the one on the left with the dowel pin
hole on top.
(2) Align the crankshaft sprocket timing mark.
(3) Align the oil pump sprocket timing mark.
(4) Remove the plug on the cylinder block and insert a
Phillips screwdriver [shank diameter 8 mm
(.31 in.)]
through the hole.
If it can be inserted as deep as 60 mm (2.4 in.) or more,the timing marks are correctly aligned. If the inserted
depth is only
20-25 mm (.8-l .O in.), turn the oil pump
sprocket one turn and realign timing marks. Then checkto ensure that the screwdriver can be inserted 60 mm
(2.4 in.) or more. Keep the screwdriver inserted until theinstallation of the timing belt is finished.,+
.
NOTEStep (4) is performed to ensure that the oil pump
sprocket is correctly positioned with reference to the
silent shafts.

P(5) Thread the timing belt over the intake side camshaft
sprocket and fix it an indicated position by a clip.
(6) Thread the timing belt over the exhaust side sprocket,
aligning the timing marks with the cylinder head top
surface using two wrenches.
(7) Fix the belt at indicated position by a clip.
(8) Thread the timing belt over the idler pulley, the oil pumpsprocket, the crankshaft sprocket and the tension
pulley in the order shown.
(9) Remove the two clips.
(1O)Lift up the tensioner pulley in the direction of arrow andtighten the center bolt.
(11)Check to see that all timing marks are lined up.
(12)Remove the screwdriver inserted in step (4) and fit the
plug.
(13)Give the crankshaft a quarter counterclockwise turn.
Then, turn it clockwise until the timing marks are lined
up again.

9-106ENGINE <2.0L DOHC Engine> - Timing Belt. ADJUSTMENT OF TIMING BELT TENSION
(1) After turning the crankshaft
l/4 turn counterclockwise,.5;;turn it clockwise to move the No. 1 cylinder to top dead
center.(2) Loosen the center bolt, and then, as shown in the
illustration, attach the special tool and a torque wrench
and apply a torque of 2.6-2.8 Nm
(1.88-2.03 ft.lbs.).If the body interferes with the special tool and the
torque wrench, use a jack to slightly raise the engine
assembly.
NOTEUse a torque wrench that is capable of measurement
within a range of
O-3 Nm (O-2.2 ft.lbs.).(3) Holding the tensioner pulley with the special tool and
torque wrench, tighten the center bolt to specification.
(4) Screw the special tool into the engine left support
bracket until its end makes contact with the tensioner
arm. At that point, screw the special tool in some more
and then remove the set wire attached to the auto
tensioner.(5) Remove the special tool.
(6) Rotate the crankshaft two complete turns clockwise
and leave it as is for about 15 minutes. Then, measure
the auto tensioner protrusion “A” (distance between
the tensioner arm and auto tensioner body) to ensure,.+
that it is up to specification.
Standard value:
3.8-4.5 mm (.15-.18 in.)
If it is out of specification, repeat steps (6) through (1)
until the specified value is obtained.
(7) If the clearance between the tensioner arm and the
auto tensioner body cannot be measured (when the
engine is being mounted, etc.), the following proce-
dures can be used to substitute for the ordinan/ methodof measurement.
@ Screw in the special tool until it contacts the
tensioner arm.
@ From that point of contact, further screw in the
special tool, screwing it in until the push rod of the
auto tensioner body is caused to move backward
and the tensioner arm contacts the auto tensioner
body.Check to be sure that the amount that the special
tool has been screwed in (when the push rod
moves backward) is the standard value.
Standard value: 2.5-3 turns

(1) Warm up the engine, then stop it.
(2) Remove the air intake hose from the throttle body.
(3) Spray cleaning solvent into the valve through the throttle
body intake port and leave it for about 5 minutes.
(4) Start the engine, race it several times and idle it for about 1minute. If the idling speed becomes unstable slightly open
the throttle valve to keep the engine running.
(5) If the throttle valve deposits are not removed, repeat steps
(3) and (4).
(6) Attach the air intake hose.

IDLE POSITION SWITCH ADJUSTMENT
Caution
N14UDAThe idle position switch has been adjusted by the manu-
facturer.Do not, therefore, disturb the setting of the idle-position
switch.
If the setting is disturbed as a result of carelessness, or if
the idle-position switch is replaced, make the necessary
setting as described below.
(1) Sufficiently loosen the tension of the accelerator cable.
(2) Disconnect the connector of the idle position switch (fixed
speed adjusting screw).
(3) Loosen the lock nut of the idle position switch (fixed speed
adjusting screw).
(4) Sufficiently loosen the idle position switch by turning it in
the counterclockwise direction and fully close the throttle
valve.Caution
Be sure to completely close the throttle valve.
(5) Connect a tester (ohm range) between the switch’s
terminal and the body.
(6) Turn down the idle position switch until it enter the “ON”
state where the switch establishes a continuity to body
(this point is called “touch point”). Turn the switch down
15/16 of a turn more from that point.
NOTEThe “touch point” refers to the point where the throttle
valve begins opening.
(7) While holding the idle position switch to make sure that it
does not turn, tighten the lock nut.
(8) Adjust the accelerator cable.
(9) Adjust the basic idle speed. (Refer to P.14-48.)
(lO)Setting the throttle position sensor.
FUEL PRESSURE TESTN14FNAO(1) Reduce the fuel pressure in the fuel line.
(Refer to
P.14-44.)(2) Disconnect the high pressure fuel hose from the delivery
pipe.Caution
Cover the hose connection with shop towel to prevent
splash of fuel that could be caused by residual pressurein the fuel pipe line.
(3) Remove the throttle body stay.
