(3) Install the timing belt around sprockets as follows.
@ Install the timing belt around the tensioner pulley
and crankshaft sprocket and secure the timing belt
onto the tensioner pulley with your left hand.
@Pulling the belt with your right hand, install it around
the oil pump sprocket.
@Install the belt around the idler pulley.
@ Turn the camshaft sprocket one tooth clockwise to align its timing mark with the cylinder head top sur-
face (see illustration in step
0). Then, pulling the
belt with both hands, install it around the camshaft
sprocket.
@ Gently raise the tensioner pulley as shown by the arrow, so that the belt does not sag, and temporar-
ily tighten the center bolt.
. ADJUSTMENT OF TIMING BELT TENSION (1) After turning the crankshaft
l/4 turn counterclockwise,
turn it clockwise to move the
No.1 cylinder to top dead
center.
(2) Loosen the center bolt, and then, as shown in the illus- tration, 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 assem-
bly.
NOTE
Use a torque wrench that is capable of measurement
within a range of
O-3 Nm (O-2.2
ftlbs.)
(3) Holding the tensioner pulley with the special tool and
torque wrench, tighten the center bolt to specification.
(4) Screw the tool into the engine left support bracket until its end makes contact with the tensioner arm. At that
point, screw the tool in some more and then remove
the set wire attached to the auto tensioner.
(5) Remove the 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 (11)
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 ordinary
method of measurement.
@Screw in the tool until it contacts the tensioner arm.
@From that point of contact, further screw in the tool,
screwing it in until the push rod of the auto ten-
sioner body is caused to move backward and the
tensioner arm contacts the auto tensioner body. Check to be sure that the amount that the tool has
been screwed in (when the push rod moves back-
ward) is the standard value.
Standard value: 2.5-3 turns

6EN0515
(3) lf
any abnormal noise IS not eliminated by racing. check the
lash adjuster
@ Stop the engine.
@ Set the engine so that cylinder
No. 1 IS positioned at
the top dead centre of the compression.
@ Press the rocker arm at the area indicated by the+
arrow mark to check whether the rocker arm is lowered
or not.
@ Slowly turn the crankshaft 360 degrees clockwise.
@ ln the same procedure as Step 0, check the rocker
arm at the area indicated by the
4 arrow mark.
@ If the rocker arm lowers easily when the part directly above the rocker arm lash adjuster is pressed, the lash
adjuster is defective and must be replaced. When re- placing the lash adjuster, bleed the air from all adjus-
ters and then assemble them. Then inspect with proce- dures
@I to 0, and confirm that there are no abnormal-
ities.
NOTE
lThe lash adjuster can be accurately checked for de-
fects with the leak down test.
l Refer to the engine service manual for the leak
down test and lash adjuster air bleeding procedure.
If the rocker arm is extremely hard when pressed
down, the lash adjuster is normal, so look for a different
cause of abnormal sound.
DASH POT INSPECTION AND ADJUSTMENT

(1) Perform after inspecting the idle rotation speed.
(2) The vehicle should be prepared as follows before the inspection.
l Engine coolant temperature:
80- 95°C
(176- 203°F)
lLights, electric cooling fan and accessories: OFF
l Transaxle: Neutral
l Steering wheel: neutral position
(3) Either set the tachometer or connect the data link connec- tor (white) to the scan tool.
NOTE
For setting the tachometer. refer to GROUP 13 - Service
Adjustment Procedures.
(4) Start the
engine.
(5) Open the throttle valve until the dash pot rod is fully
stroked.
(6) Gradually close the throttle valve until you find the point where the throttle lever touches the dash pot rod (the dashpot begins to shorten).
Maintain the throttle valve at this touching point,
(7) Check the engine speed (speed when the dash pot begins to operate).
Standard value: 3,900
f 200 rpm
(8) If outside the standard value, loosen the rod’s lock nut and turn the rod to adjust.
(9) To release the maintained state of the throttle valve, check that the engine speed gradually decreases to the idle speed, (10)Disconnect
the closed throttle position switch connector
(fixed SAS).

BELT
Caution
1. Before checking, turn the engine one time or more.
2.If the belt tension is too strong, it is possible that the
generator or water pump bearing is damaged. If the belt tension is too weak, however, sounds of its slip-
ping will be heard, and the belt’s service life will be
reduced.
1.Loosen the generator pivot nut
2. Loosen the lock bolt of the belt tension adjuster.
3. Using the adjustment bolt, adjust the belt tension to
specified.
4. Tighten the lock bolt.
5.Tighten the generator pivot nut.
6.Check the deflection or the tension of the belt; readjust if
necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been used for as long as five minutes or more.
DEFLECTION ADJUSTMENT OF POWER STEERING OIL

32. DISCONNECTION OF POWER STEERING OIL PUMP Disconnect the oil pump with hoses from the bracket.
NOTE
The removed power steering oil pump should be fastened(by using rope, etc.) in a position that will not interfere
with the removal/installation of the engine assembly.
33. DISCONNECTION OF AIR CONDITIONING COMPRESSOR
Disconnect air conditioning compressor connector and re-
move it with hoses from the compressor bracket.
NOTE
The removed air conditioning compressor should be fas-
tened (by using rope, etc.) in a position that will not inter-
fere with the removal/installation of the engine assembly. OlA0177
37. DISCONNECTION OF ENGINE MOUNT BRACKETBefore removing the engine mount bracket installation
bolt, use a chain block or similar arrangement to suspend
the engine assembly (to the extent that there is no
looseness of the chain).
39. REMOVAL OF ENGINE ASSEMBLY After checking that the cables, hoses, harness connec-
tors, etc. are all removed, slowly raise the chain block tolift the engine assembly upward out of the engine
