+If the belt deflection of the current belt is out of the ªLimit
for re-tighteningº, adjust to the ªAdjusted valueº.
+When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning crankshaft two turns or more, re-adjust it to
the specified value to avoid variation in deflection
between pulleys.
+Make sure the belts are fully fitted into the pulley grooves
during installation.
+Handle with care to avoid smearing the belts with oil or
cooling water etc.
+Do not twist or bend the belts with strong force.

Trouble Diagnosis of Turbocharger=NJEM0104S0206Preliminary check:
+Check that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
+Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
+If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.
