FAILURE
(Woven fabric on outside,
circumference of belt has cracked or
separated from body of belt)
1. Tension sheeting contacting
stationary object
1. Correct rubbing condition
2. Excessive heat causing woven
fabric to age
2. Replace belt
3. Tension sheeting splice has
fractured
3. Replace belt
CORD EDGE FAILURE
(Tensile member exposed at edges
of belt or separated from belt body)
1. Incorrect belt tension
1. Inspect/Replace tensioner if
necessary

REMOVAL
Drive belts on 5.2L/5.9L engines are equipped with
a spring loaded automatic belt tensioner (Fig. 9).
This belt tensioner will be used on all belt configura-
tions, such as with or without power steering or air
conditioning. For more information (Refer to 7 -
COOLING/ACCESSORY
DRIVE/BELT
TENSION-
ERS - REMOVAL).
(1) Attach a socket/wrench to pulley mounting bolt
of automatic tensioner (Fig. 9).
(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.

INSTALLATION
CAUTION: When installing serpentine accessory
drive belt, the belt must be routed correctly. If not,
engine may overheat due to water pump rotating in
wrong direction. Refer to (Fig. 10) for correct engine
belt routing. The correct belt with correct length
must be used.
(1) Position drive belt over all pulleys except idler
pulley. This pulley is located between generator and
A/C compressor.
(2) Attach a socket/wrench to pulley mounting bolt
of automatic tensioner (Fig. 9).
(3) Rotate socket/wrench clockwise. Place belt over
idler pulley. Let tensioner rotate back into place.
Remove wrench. Be sure belt is properly seated on
all pulleys.
(4) Check belt indexing marks (Refer to 7 - COOL-
ING/ACCESSORY
DRIVE/BELT
TENSIONERS
-
INSTALLATION).
The tensioner is equipped with an indexing arrow
on back of tensioner and an indexing mark on ten-
sioner housing. If a new belt is being installed, arrow
must be within approximately 3 mm (1/8 in.) of
indexing mark. Belt is considered new if it has been
used 15 minutes or less. If this specification cannot
be met, check for:
• The wrong belt being installed (incorrect length/
width)
• Worn bearings on an engine accessory (A/C com-
pressor, power steering pump, water pump, idler pul-
ley or generator)
• A pulley on an engine accessory being loose
• Misalignment of an engine accessory
• Belt incorrectly routed. Refer to (Fig. 10)

OIL COOLERS
DESCRIPTION
CAUTION: On in-radiator type oil coolers, if trans-
mission oil cooler is leaking, engine coolant may
enter cooler, or transmission oil may enter engine
cooling system. Both engine cooling system and
transmission oil circuit should be drained, flushed,
and inspected (Fig. 2).
There are two types of transmission oil coolers
used. One type of cooler is the in-radiator type or oil
to coolant type. This type oil cooler is not serviceable.
The second type used is a remote type auxiliary oil
cooler or oil to air cooler. The oil to air type cooler is
located in front of the radiator, and is serviceable
(Fig. 1).

an
AM/FM/cassette
(RAS
sales
code)
receiver,
and
speakers in four locations. Several combinations of
radio receivers and speaker systems are offered as
optional equipment on this model. The audio system
uses an ignition switched source of battery current so
that the system will only operate when the ignition
switch is in the On or Accessory positions. The audio
system includes the following components:
• Antenna
• Clockspring (with remote radio switches only)
• High-line Central Timer Module (CTM) (with
remote radio switches)
• Power amplifier (with premium speaker system
only)
• Radio noise suppression components
• Radio receiver
• Remote radio switches (optional with RAZ radio
receiver only)
• Speakers
