3. Alternator belt tension
The alternator belt is properly
tense if it deflects 10 to
12 mm (0.39 to 0.47 in) as it
is depressed with a finger be-
tween the pulley and pulley of
the long distance side.
Excess i ve tens ion can cause
quick wear of the belt and
bearings of the water pump and
the alternator. Excessive
slackness or presence of oil on
the belt, on the other hand,
can lead to engine overheating
and insufficient charging due
to a slipping belt.
CAUTION:
Never attempt to adjust tension of the fan belt while the
engine is in operation.
