camshaft sprocket.
Caution
As the purpose of this procedure is to apply the
proper amount of tension on the timing belt, be
sure not to rotate the crankshaft counterclockwise
or place pressure on the belt to check the amount of
tension.(4) Apply force on tensioner toward turning direction, (in
the direction of the arrow) such that no portion of the
belt raises out in portion A, place the belt on the
camshaft sprocket such that the belt sprocket teeth arefully engaged.
(5) Tighten the tensioner installation bolt and tensioner
spacer in that order.
Caution
If the tensioner spacer is tightened first, the ten-
sioner will rotate with it and belt tension be thrown
out of adjustment. Always tighten the bolt first.(6) Check to see that the clearance between the outside of
the belt and the cover are within the standard value by
grasping the tension side (between the camshaft
sprocket and oil pump sprocket) of the centre part of
the timing belt between the thumb and index finger.
Standard value: 12 mm (.40 in.)

-35. INSTALLATION OF SPACER
(1) Apply a thin coat of engine oil to the outer circumfer-
ence of the spacer.
(2) Install the spacer with the chamfered end facing the oil
seal.
NOTEIf the spacer is installed adversely, the oil seal may be
damaged, resulting in the oil leaks.
33. INSTALLATION OF TIMING BELT “B”
(1) Ensure that crankshaft sprocket “B” timing mark and
the silent shaft sprocket timing mark are aligned.
(2) Fit timing belt “B” over crankshaft sprocket “B” and
the silent shaft sprocket. Ensure that there is no slack inthe belt.
.ADJUSTMENT OF TIMING BELT “B” TENSION
(1) Temporarily fix the timing belt “B” tensioner such that
the center of the tensioner pulley is to the left and
above the center of the installation bolt, and temporarilyattach the tensioner pulley so that the flange is toward
the front of the engine.
(2) Holding the timing belt “B” tensioner up with your
finger in the direction of the arrow, place pressure on
the timing belt so that the tension side of the belt is
taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, 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.
(3) To ensure that the tension is correct, depress the belt
(point A) with a finger. If not, adjust.
Standard value: 5-7 mm
(.20-.28 in.)

tool, install the pressure switch.
Specified sealant: MOPAR Part No.4318034
orequivalent
Caution
1. Do not let sealant ooze out of the top of the
thread area.
2. Do not overtighten the pressure switch.
(2) Install the oil pressure switch terminals.
5. INSTALLATION OF OIL COOLER
First insert the oil cooler projecting stopper in the oil filter
bracket groove and then tighten the oil cooler bolts.lu3. INSTALLATION OF OIL FILTER
Wipe clean the mounting surface on the filter bracket.
Then, apply a thin coat of engine oil to filter O-ring and
tighten the oil filter by hand.
Caution
-.Never use a wrench to tighten the oil filter.

TROUBLESHOOTING
When checking and correcting engine troubles, it is
important to start with inspection of the basic
systems.
In case you have such troubles as (1) engine start
failure, (2) rough idling or (3) poor acceleration,
therefore, you should first check the following basic
systems:
(1) Power supply
0 Batteryl
Fusible linkl
Fuse
(2) Body ground
(3) Fuel supplyl
Fuel linel
Fuel filter
l
Fuel pump
N14EBBH
(4) Ignition systeml

0 Ignition coil
(5) Emission control systeml
Crankcase ventilation systeml
Exhaust gas recirculation systeml

(6) Others
0 Ignition timing
l
Idle speed
Troubles with the MPI system are often caused by
poor contact of harness connector. It is, therefore,
important to check harness connector contact.
