*The 1.6L engine is not equipped with
silent shafts. Disregard all instructions per-
taining to silent shafts if working on that en-
gine.
1. Disconnect the negative battery cable.
2. Remove the engine undercover.
3. If necessary, remove the coolant reservoir.
4. Using the proper equipment, slightly raise
the engine to take the weight off the side engine
mount. Remove the engine mount bracket.
5. Remove the drive belts, tension pulley brack-
ets, water pump pulley and crankshaft pulley.
6. Remove all attaching screws and remove the
upper and lower timing belt covers.
7. Rotate the crankshaft clockwise and align the
timing marks so No. 1 piston will be at TDC of the
compression stroke. At this time the timing marks on
the camshaft sprocket and the upper surface of the
cylinder head should coincide, and the dowel pin of
the camshaft sprocket should be at the upper side.
*Always rotate the crankshaft in a clockwise
direction. Make a mark on the back of the
timing belt indicating the direction of rotation
so it may be reassembled in the same direc-
tion if it is to be reused.
8. Remove the auto tensioner and remove the
outermost timing belt.
9. Remove the timing belt tensioner pulley, ten-
sioner arm, idler pulley, oil pump sprocket, special
washer, flange and spacer.
10. Remove the silent shaft (inner) belt tensioner
and remove the belt.
To install: 11. Align the timing marks on the crankshaft
sprocket and the silent shaft sprocket. Fit the inner
timing belt over the crankshaft and silent shaft
sprocket. Ensure that there is no slack in the belt.
12. While holding the inner timing belt tensioner
with your fingers, adjust the timing belt tension by
applying a force towards the center of the belt, until
the tension side of the belt is taut. Tighten the ten-
sioner bolt.
*When tightening the bolt of the tensioner,
ensure that the tensioner pulley shaft does
not rotate with the bolt. Allowing it to rotate
with the bolt can cause excessive tension on
the belt.
13. Check belt for proper tension by depressing
the belt on it’s long side with your finger and noting
the belt deflection. The desired reading is 0.20-0.28
in. (5-7mm). If tension is not correct, readjust and
check belt deflection.
14. Install the flange, crankshaft and washer to
the crankshaft. The flange on the crankshaft sprocket
must be installed towards the inner trming belt
sprocket. Tighten bolt to 80-94 ft. Ibs. (110-130
Nm).
15. To install the oil pump sprocket, insert a
Phillips screwdriver with a shaft 0.31 in. (8mm) in di-
ameter into the plug hole in the left side of the cylin-
der block to hold the left silent shaft. Tighten the nut
to 36-43 ft. Ibs. (50-60 Nm).
16. Using a wrench, hold the camshaft at it’s
hexagon between journal No. 2 and 3, then tighten
the bolt to 58-72 ft. Ibs. (80-100 Nm). If no hexagon
is present between journal No. 2 and 3, hold the
sprocket stationary with a spanner wrench while
tightening the retainer bolt.
17. Carefully push the auto tensioner rod in until
the set hole in the rod aligns with the hole in the
cylinder. Place a wire into the hole to retain the rod.
18. Install the tensioner pulley onto the tensioner
arm. Locate the pinhole in the tensioner pulley shaft
to the left of the center bolt. Then, tighten the center
bolt finger-tight.
19. When installing the timing belt, turn the 2
camshaft sprockets so their dowel pins are located on
top. 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 1 tooth in
the counterclockwise direction. This should be taken
into account when installing the timing belts on the
sprocket.
*Both camshaft sprockets are used for the
intake and exhaust camshafts and are pro-
vided with 2 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
camshafl sprocket, use the 1 on the left with
the dowel pin hole on top.
20. Align the crankshaft sprocket and oil pump
sprocket timing marks.
21. After alignment of the oil pump sprocket tim-
ing marks, remove the plug on the cylinder block and
insert a Phillips screwdriver with a shaft diameter of
0.31 in. (8mm) through the hole. If the shaft can be
inserted 2.4 in. deep, the silent shaft is in the correct
position. If the shaft of the tool can only be inserted
0.61 .O in. (2C-25mm) deep, turn the oil pump
sprocket 1 turn and realign the marks. Reinsert the
tool making sure it is inserted 2.4 in. deep. Keep the
tool inserted in hole for the remainder of this proce-
dure.
*The above step assures that the oil pump
socket is in correct orientation to the silent
shafts. This step must not be skipped or a vi-
bration may develop during engine opera-
tion.
22. Install the timing belt as follows:
a. Install the timing belt around the intake
camshaft sprocket and retain it with 2 spring
clips or binder clips.
b. Install the timing belt around the exhaust
sprocket, aligning the timing marks with the
cylinder head top surface using 2 wrenches. Re-
tain the belt with 2 spring clips. c. Install the timing belt around the idler pul-
ley, oil pump sprocket, crankshaft sprocket and
the tensioner pulley. Remove the 2 spring clips.
d. Lift upward on the tensioner pulley in a
clockwise direction and tighten the center bolt.
Make sure all timing marks are aligned.
e. Rotate the crankshaft ‘14 turn counterclock-
wise. Then, turn in clockwise until the timing
marks are alrgned again.
23. To adjust the timing (outer) belt, turn the
crankshaft ‘14 turn counterclockwise, then turn it
clockwise to move No. 1 cylinder to TDC.
24. Loosen the center bolt. Using tool
MD998738 or equivalent and a torque wrench, apply
a torque of 22-25 inch. Ibs. (2.6-2.8 Nm). Tighten
the center bolt.
25. Screw the special tool into the engine left
support bracket until its end makes contact with the
tensioner arm. At this point, screw the special tool in
some more and remove the set wire attached to the
auto tensioner, if the wire was not previously re-
moved. Then remove the specral tool.
26. Rotate the crankshaft 2 complete turns clock-
wise and let it sit for approximately 15 minutes. Then,
measure the auto tensioner protrusion (the distance
between the tensioner arm and auto tensioner body)
to ensure that it is within 0.15-0.18 in. (3.8-4.5mm).
If out of specification, repeat Step l-4 until the spec-
ified value is obtained.
27. If the timing belt tension adjustment is being
performed with the engine mounted in the vehicle,
and clearance between the tensioner arm and the auto
tensioner body cannot be measured, the following al-
ternative method can be used:
a. Screw in special tool MD998738 or equiv-
alent, until its end makes contact with the ten-
sioner arm.
b. After the special tool makes contact with
the arm, screw it in some more to retract the auto
tensioner pushrod while counting the number of
turns the tool makes until the tensioner arm is
brought into contact with the auto tensioner
body. Make sure the number of turns the special
tool makes conforms with the standard value of
21/a-3 turns.
c. Install the rubber plug to the timing belt
rear cover.
28. Install the timing belt covers and all related
items.
29. Connect the negative battery cable.

ENGlNEANDENGlliEOVERHAUL 3-39
To install: IO. Align the timing marks of the silent shaft
sprockets and the crankshaft sprocket with the timing
marks on the front case.
11. Wrap the timing belt around the sprockets so
there is no slack in the upper span of the belt and the
timing marks are still aligned.
12. Install the tensioner pulley and move the pul-
ley by hand so the long side of the belt deflects about
l/d in. (6mm).
13. Hold the pulley tightly so the pulley cannot
rotate when the bolt is tightened. Tighten the bolt to
15 ft. Ibs. (20 Nm) and recheck the deflection
amount.
14. Install the timing belt tensioner fully toward
the water pump and tighten the bolts. Place the upper
end of the spring against the water pump body.
15. Align the timing marks of the camshaft,
crankshaft and oil pump sprockets with their corre-
sponding marks on the front case or rear cover.
*There is a possibility to align all timing
marks and have the oil pump sprocket and
silent shaft out of time, causing an engine vi-
bration during operation. If the following step
is not followed exactly, there is a 50 percent
chance that the silent shaft alignment will be
180 degrees off.
16. Before installing the timing belt, ensure that
the left side (rear) silent shaft (oil pump sprocket) is
in the correct position as follows:
a. Remove the plug from the rear side of the
block and insert a tool with shaft diameter of
0.31 in. (8mm) into the hole.
b. With the timing marks still aligned, the
shaft of the tool must be able to go in at least
2’13 in. (59mm). If the tool can only go in about
1 in. (25mm), the shaft is not in the correct ori-
entation and will cause a vibration during engine
operation. Remove the tool from the hole and
turn the oil pump sprocket 1 complete revolution.
Realign the timing marks and insert the tool. The
shaft of the tool must go in at least 21/3 in.
(59mm).
c. Recheck and realign the timing marks.
d. Leave the tool in place to hold the silent
shaft while continuing
17. Install the belt to the crankshaft sprocket, oil
pump sprocket, then camshaft sprocket, in that order.
While doing so, make sure there is no slack between
the sprocket except where the tensioner is installed.
18. Recheck the timing marks’alignment. If all
are aligned, loosen the tensioner mounting bolt and
allow the tensioner to apply tension to the belt.

19. Remove the tool that is holding the silent
shaft and rotate the crankshaft a distance equal to 2
teeth on the camshaft sprocket. This will allow the
tensioner to automatically apply the proper tension
on the belt. Do not manually overtighten the belt or it
will howl.
20. Tighten the lower mounting bolt first, then the
upper spacer bolt.
21. To verify correct belt tension, check that the
deflection at the longest span of the belt is about 1/2
in. (13mm).
22. The installation of the timing belt covers and
all related items, is the reverse of the removal proce-
dure. Make sure all pieces of packing are positioned
in the inner grooves of the covers when installing.

too tight
21. Install the timing belt tensioner fully toward
the water pump and temporarily tighten the bolts.
Place the upper end of the spring against the water
pump body. Align the timing marks of the cam,
crankshaft and oil pump sprockets with the corre-
sponding marks on the front case or head.
*If the following steps are not followed ex-
actly, there is a chance that the silent shaft
alignment will be 180 degrees off. This will
cause a noticeable vibration in the engine
and the entire procedure will have to be re-
peated.
22. Before installing the timing belt, ensure that
the left side silent shaft is in the correct position.
*It is possible to align the timing marks on
the camshaft sprocket, crankshaft sprocket
and the oil pump sprocket with the lefl bal-
ance shaft out of alignment.
23. With the timing mark on the oil pump pulley
aligned with the mark on the front case, check the
alignment of the left balance shaft to assure correct
shaft timing. a. Remove the plug located on the left side of
the block in the area of the starter.
b. Insert a tool having a shaft diameter of 0.3
in. (8mm) into the hole.
c. With the timing marks still aligned, the tool
must be able to go in at least 2l/s in. (59mm). If
it can only go m about 1 in. (25mm), turn the oil
pump sprocket one complete revolution.
d. Recheck the position of the balance shaft
with the timing marks reahgned. Leave the tool in
place to hold the silent shaft while continuing.
24. Install the belt to the crankshaft sprocket, oil
pump sprocket and the camshaft sprocket, in that or-
der. While doing so, be sure there is no slack be-
tween the sprockets except where the tensioner will
take it up when released.
25. Recheck the timing marks’ alignment.
26. If all are aligned, loosen the tensioner mount-
ing bolt, and allow the tensioner to apply tension to
the belt.
27. Remove the tool that is holding the silent
shaft in place and turn the crankshaft clockwise a dis-
tance equal to two teeth of the camshaft sprocket.
This will allow the tensioner to automatically tension
the belt the proper amount.
Do not manually apply pressure to the ten-
sioner. This will overtighten the belt and will
cause a howling noise.
28. First tighten the lower mounting bolt and then
tighten the upper spacer bolt.
If any binding is felt when adiustino the tim-
