Alternator belt and water pump tension
The belts are properly tense if
they deflect 10 to 12 mm (0.39
to
0.47
in)
as
they
are
de-
pressed
wi th
a
finger
between
the
pulley
and
pulley
of
the
long distance side.
Excessi ve
tension can cause quick wear of
the
belt
and
bearings
of
the
water pump and the al ternator.
Excessive slackness or presence
of
oil
on
the
belt,
on

overheating
and

charging
due
to
a
slipping
belt.

Never
attempt
to adjust
tension of
the
fan
belt while the
engine is in operation.
