Cooling Fan Installation
Inspect fan belt and pulleys for damage.
Fan belt must not have any cracks or contact
bottom of pulley grooves.
Be sure there is no oil on fan belt.
If fan belt is worn, oily, or damaged, clean or
replace, as necessary.
Fan Belt Tensioning
Particular attention should be paid to
V-belt tension, as slipping belts are
the cause of many other problems in
accessory drives as well as in the
cooling system. Low belt tension can
excessive belt and pulley wear.
A slipping belt will not drive the alternator to full output,
eventually leading to battery discharge problems. A belt
which has been slipping will be glazed and cracked.
Such a belt should be replaced. Excessive belt tension
will create an overload condition in the alternator front
bearing and in water pump bearings.
