<When using a tension gauge>
Use a belt tension gauge to check that the belt tension is
within the standard value.
<Belt deflection check>
Apply approx. 100 N of force to the middle of the drive belt
between the pulleys (at the place indicated by the arrow)
and check that the amount of deflection is within the
standard value.
ALTERNATOR DRIVE BELT TENSION ADJUSTMENT
(1) Loosen the nut of the alternator pivot bolt.
(2) Loosen the lock bolt.
(3) Use the adjusting bolt to adjust the belt tension and belt
deflection to the standard values.

DRIVE BELT TENSION CHECK AND ADJUSTMENT
<4G6>
(1) Check that the indicator marking of the auto-tensioner is
within the range as shown in the illustration A of the
tensioner bracket.
Caution
Inspection must be carried out after turning the
crankshaft clockwise for more than once.
(2) If the marking is outside the range as shown in the
illustration A, replace the drive belt.
NOTE
Due to the adoption of the auto-tensioner, no adjustment
for belt tension is required.
A3.
CHECK IGNITION CABLES FOR DAMAGE
(1) Check the ignition cable and rubber cap for damage or
weakness, and check the installation condition.
(2) Check the ignition cable and spark plug, distributor, and
ignition coil connections for contamination, dirt, etc.
(3) If dirty, clean it; if damaged, replace it.
A6.
REPLACE ENGINE TIMING BELT (EXCEPT
VEHICLES WITH TIMING CHAIN)
For information concerning the replacement procedures,
refer to the Workshop Manual.

CHECK OPERATION OF CRANKCASE
EMISSION CONTROL SYSTEM
(PETROL-POWERED VEHICLES)
BREATHER HOSE
(1) Inspect the blow-by hose for cracks or damage.
(2) Clean the inside of the blow-by gas hoses if necessary.
(3) Inspect the ventilation filter for clogging.
VENTILATION HOSE
(1) Check entire circumference and length of hoses using a
mirror as required.
(2) Check all clamps for tightness and the connections for
leakage.
(3) Hoses should be replaced immediately if there is any
evidence of deterioration or damage.
POSITIVE CRANKCASE VENTILATION SYSTEM CHECK
(1) Remove the ventilation hose from the PCV (Positive
crankcase ventilation) valve.
(2) Remove the PCV valve from the rocker cover.
(3) Reinstall the PCV valve at the ventilation hose.
(4) Start the engine and run at idle.
(5) Place finger at the opening of the PCV valve and check
that vacuum of the intake manifold is felt.
NOTE
At this moment, the plunger in the PCV valve moves
back and forth.
(6) If vacuum is not felt, clean the PCV valve or replace it.

PCV VALVE CHECK
(1) Insert a thin rod into the PCV valve from the side shown
in the illustration (rocker cover installation side), and
move the rod back and forth to check that the plunger
moves.
(2) If the plunger does not move, there is clogging in the
PCV valve. In this case, clean or replace the PCV valve.
A8.
REPLACE SPARK PLUGS
After removing old spark plugs, install new ones and tighten
them at the specified torque.
A9.
CHECK RADIATOR HOSES FOR DAMAGE
AND PROPER CONNECTION
(1) Check entire circumference and length of hoses, using a
mirror as required.
(2) Check that hoses installed in grommets pass through
the centre of the grommets.
(3) Check all clamps for tightness and connections for
leakage.
A10. CHECK ENGINE COOLANT LEVEL IN
RESERVOIR
Check that the coolant level is between the “FULL” and
“LOW” lines when the engine is at the normal operating
temperature.
