DRIVE BELTS - 5.9L DIESEL (Continued)
CONDITION
NOISE (Objectional squeal, spueak,
or rumble is heard or felt while drive
belt is in operation)
TENSION SHEETING FABRIC
FAILURE
(Woven fabric on outside,
circumference of belt has cracked or
separated from body of belt)
CORD EDGE FAILURE
(Tensile member exposed at edges
of belt or separated from belt body)
REMOVAL
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.
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.
Drive belts on diesel engines are equipped with a
spring loaded automatic belt tensioner (Fig. 20).
(Fig. 20)displays the tensioner for vehicles
without air conditioning.
This belt tensioner will be used on all belt config-
urations, such as with or without air conditioning.
For more information, (Refer to 7 - COOLING/AC-
CESSORY DRIVE/BELT TENSIONERS - DESCRIP-
TION).
(1) A 3/8 inch square hole is provided in the auto-
matic belt tensioner (Fig. 20). Attach a 3/8 inch
drive-long handle ratchet to this hole.
(2) Rotate ratchet and tensioner assembly counter-
clockwise (as viewed from front) until tension has
been relieved from belt.
POSSIBLE CAUSES
1. Incorrect belt tension
2. Bearing noise
3. Belt misalignment
4. Belt to pulley mismatch
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
