x 38(.23 x 1.50)(3) Turn the crankshaft clockwise by two teeth of the
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.)

JMANIFOLD VACUUM INSPECTION
NO9FNAO(1) Before inspection and adjustment, put the vehicle into the
following state.
l Engine coolant temperature:
85-g5”C (185-205°F)
l Lights, electric, cooling fan, and accessories: OFF
lTransaxle: Neutral (N or
P for vehicles with an automa-
tic transaxle)
l Steering wheel: Neutral position
(2) Check that the idling revolution speed is normal.
(3) Remove the PCV hose from the PCV valve and attach a
vacuum gauge.
(4) Check that the negative pressure at the intake manifold
during idle revolution is normal.
Standard value:: 490
mmHg (19.3 in.Hg): 480
mmHg (18.9 in.Hg)(5) If outside the standard value, isolate the cause by referring
to the following table and repair the fault.
ymptomICause1 Remedy
The vacuum gauge reading is less than
standard value, but the pointer is
stable.
The vacuum gauge pointer swingsslowly.
l Ignition timing is retarded.
l Air mixture concentration too
rich.
l Adjust the ignition timing.
l Check ECI-MULTI system.
The vacuum gauge pointer drops
irre-gularly.l Air mixture concentration too
lean.
l Check ECI-MULTI system.
The vacuum gauge pointer drops inter-mittently to 30 to 160
mmHg (1.2 to
6.3 in.Hg).
The vacuum gauge pointer drops sud-
denly from the normal reading to 250
mmHg (9.8 in.Hg), then returns tonormal.
l Incomplete close contact of in-
take and exhaust valve seat.
l Broken cylinder head gasket
l Check and repair the valve.
l Replace cylinder head gasket.
