DRIVE BELTS - 2.4L (Continued)
CONDITION
NOISE (Objectionable squeal,
squeak, 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
REMOVAL
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 let tensioner arm snap back to
the freearm position, severe damage may occur to
the tensioner.
Belt tension is not adjustable. Belt adjustment is
maintained by an automatic ( spring load ) belt ten-
sioner.
(1) Disconnect negative battery cable from battery.
(2) Rotate belt tensioner until it contacts its stop.
Remove belt, then slowly rotate the tensioner into
the freearm position.
POSSIBLE CAUSES
1. Belt slippage
2. Bearing noise
3. Belt misalignment
4. Belt to pulley mismatch
5. Driven component induced
vibration
6. System resonant frequency
induced vibration
1. Tension sheeting contacting
stationary object
2. Excessive heat causing woven
fabric to age
3. Tension sheeting splice has
fractured
1. Excessive tension
2. Belt contacting stationary object
3. Pulley(s) out of tolerance
4. Insufficient adhesion between
tensile member and rubber matrix
