NOTE: To remove the water pump pulley, it MUST
first be positioned between water pump housing
and drive hub. The pulley can then be removed with
the water pump assembly.
(5) Rotate pulley until openings in pulley align
with water pump drive hub spokes (Fig. 28). Move
pulley inward between pump housing and hub (Fig.
28).
(6) Position pulley to allow access to water pump
mounting bolts. Remove water pump mounting bolts
(Fig. 29).
(7) Remove water pump with the pulley loosely
positioned between hub and the pump body.
(8) Remove and discard the seal.
(9) Clean seal groove and sealing surfaces on
pump and timing chain case cover. Take care not to
scratch or gouge sealing surfaces.
CLEANING
Clean gasket mating surfaces as necessary.
INSPECTION
Replace the water pump if it has any of the follow-
ing defects.
(1) Damage or cracks on the pump body.
(2) Coolant leaks; this will be evident by a wet
stream of coolant running down the pump body and
components below. A thin stain below the weep hole
reservoir slot (Fig. 30) is considered normal opera-
tion.
(3) Impeller rubs inside of chain case cover.
(4) Excessively loose or rough turning bearing.
NOTE: A weepage stain that is black, brown, or grey
is considered normal, if it is dry. If the weep
appears wet; pressure test the cooling system at
15±18 psi and observe the weep area. If weep arearemains unchanged, do not replace the water pump
for this condition. Replace the water pump, if a
steady flow of engine coolant is evident from the
weep hole/reservoir slot (Fig. 30) (shaft seal failure).
Be sure to perform a thorough analysis before
replacing water pump.
INSTALLATION
(1) Install new seal into water pump housing
groove (Fig. 31).
NOTE: The water pump pulley MUST be positioned
loosely between the pump housing and drive hub
BEFORE water pump installation.

AUDIO/VIDEO
DESCRIPTION
An audio system is standard factory-installed
equipment on this model. A rear seat video system is
an available option. Several combinations of radio
receivers are offered on this model. The audio/video
system uses an ignition switched source of battery
current so that the system will only operate when
the ignition switch is in the RUN or ACCESSORY/
ACCESSORY DELAY positions.
The audio system includes the following compo-
nents:
²Antenna
²CD changer (if equipped)
²DVD player (if equipped)²Radio noise suppression components
²Radio receiver
²Speakers
²Video screen (if equipped)
Certain functions and features of the audio/video
system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communication Interface (PCI) bus network. The
data bus network allows the sharing of sensor infor-
mation. For diagnosis of these electronic modules or
of the data bus network, the use of a DRB IIItscan
tool and the proper Diagnostic Procedures manual
are recommended.
Refer to the appropriate wiring information in this
service manual for complete standard and premium
audio system circuit diagrams. The wiring informa-
tion includes proper wire and connector repair proce-
