(9) Remove the air conditioning drive belt and the generator drive belt.
(10)Removle the access covers. There are easily removed by
inserting a screwdriver into the slots indicated by the raised
arrows in the timing belt cover and twisting. (1l)lnset-t
the special tool (MD998051-01)
from the pivot side
access hole and loosen the tension spacer (with a tensioner lock nut on it) 1 to 2 turn.
Next insert a 14 mm socket wrench from the slot side
access hole and loosen the tensioner lock bolt 1 to 2 turn.
(12)Turn the crankshaft clockwise by two teeth of the camshaft
sprocket.
(13)First ticjhten the timing belt tensioner installation bolt (on
the
lo&er side), and then tighten the tensioner spacer
(upper side).
Caution
Be sure to tighten the bolt (lower side) first. lf the
tensioner spacer of pivot side is tightened first, the
tensioner will rotate with it and belt tension may
becorn; loose.
(14)lnstall the access cover. The access cover may be easily
installeNd by passing the hooks between the guides and
sliding it in.
(15)lnstall the air conditioning drive belt and generator drive
belt and adjust the slack. (Refer to P.l
l-l 2.)
(16)lnstall the timing belt front upper cover.
(17)lnstall the engine mounting bracket.
(18)lnstall the spark plugs.
(19)lnstall the left side undercover panel.

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 b’elt tension is too weak, however, sounds of its
slipping 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
PUMP DRIVE BELT
1. Loosen power steering oil pump fixing bolt.
2. Move power steering pump, tension belt moderately and adjust deflection.
3. Tighten fixing bolts.
4. Run the engine one time or more.
5. Check the belt deflection. Readjust, if necessary.
TENSION ADJUSTMENT OF THE AIR CONDITIONING
COMPRESSOR DRIVE BELT
1. Loosen tension pulley fixing bolt A.
2. Adjust belt deflection with adjusting bolt B.
3. Tighten fixing bolt A.
4. Run the engine one time or more. 5. Check the belt tension. 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.
