<WHEN USING THE TENSION GAUGE>
Tension
gauge
Alternator
pulley
Use a belt tension gauge to check that the belt ten-
sion is within the standard value.
<BELT DEFLECTION CHECK>
Approximately
100N
Deflection
Alternator pulley
Apply approximately 100 N of force to the middle of
the drive belt between the pulleys (at the place indi-
cated by the arrow) and check that the amount of
deflection is within the standard value.
When the belt tension is adjusted by measuring the
deflection, adjust it with a tool for vibration frequency
measurement or tension measurement afterward.
If not within the standard value, adjust the belt ten-
sion by the following procedure.
Adjusting
bolt
Alternator
fixing nut
Alternator pivot bolt
1. Loosen the nut of the alternator pivot bolt.
2. Loosen the alternator fixing nut.
3. Use the adjusting bolt to adjust the belt tension
and belt deflection to the standard values.

A2. CHECK VACUUM PUMP OIL HOSE
FOR DAMAGE
1. Inspect the surface of hose for evidence of heat
and mechanical damage.
A3. CHECK INTAKE AIR HOSE AND
TURBOCHARGER OIL HOSE FOR
DAMAGE
Turbocharger
1. Inspect the intake air hoses for cracks or dam-
age.
2. Inspect the turbocharger oil hoses for cracks or
damage.
A4. REPLACE ENGINE TIMING BELT
<EXCEPT VEHICLES WITH TIMING
CHAIN>
For information concerning the replacement proce-
dures, refer to the Workshop Manual.
