NOTE: The belt routing schematics are published
from the latest information available at the time of
publication. If anything differs between these sche-
matics and the Belt Routing Label, use the sche-
matics on Belt Routing Label.This label is located in
the engine compartment.
CAUTION: Do not attempt to check belt tension with
a belt tension gauge on vehicles equipped with an
automatic belt tensioner. Refer to Automatic Belt
Tensioner in this group.
Drive belts on these engines are equipped with a
spring loaded automatic belt tensioner (Fig. 11). This
belt tensioner will be used on all belt configurations,
such as with or without power steering or air condi-
tioning. For more information, (Refer to 7 - COOL-
ING/ACCESSORY DRIVE/BELT TENSIONERS -
DESCRIPTION).
(1) Attach a socket/wrench to pulley mounting bolt
of automatic tensioner (Fig. 11).
(2) Rotate tensioner assembly clockwise (as viewed
from front) until tension has been relieved from belt.
(3) Remove belt from idler pulley first.
(4) Remove belt from vehicle.
POSSIBLE CAUSES
1. Incorrect belt tension
2. Bearing noise
3. Belt misalignment

5. Driven component induced
vibration
1. Tension sheeting contacting
stationary object
2. Excessive heat causing woven
fabric to age
3. Tension sheeting splice has
fractured
1. Incorrect belt tension
2. Belt contacting stationary object
3. Pulley(s) out of tolerance
4. Insufficient adhesion between
tensile member and rubber matrix
