INSTALLATION - RHD
(1) Install the ICU on the mounting bracket (Fig.
5). Install the 3 bolts (Fig. 5) attaching the ICU to
the mounting bracket. Tighten the 3 mounting bolts
to a torque of 11 N´m (97 in. lbs.).
CAUTION: The ICU mounting bracket to front sus-
pension cradle mounting bolts have a unique corro-
sion protection coating and a special aluminum
washer. For this reason, only the original, or origi-
nal equipment Mopar replacement bolts can be
used to mount the ICU bracket to the front suspen-
sion crossmember.
(2) Install the ICU and its mounting bracket as an
assembly on the front suspension crossmember.
Install the 3 bolts attaching the ICU bracket to the
crossmember (Fig. 4). Tighten the 3 mounting bolts
to a torque of 28 N´m (250 in. lbs.).
CAUTION: Because of the flexible section in the pri-
mary and secondary brake tubes, and the brake
tubes between the HCU and the proportioning
valve, the brake tubes must be held in proper ori-
entation when tightened and torqued. These tubes
must not contact each other or other vehicle com-
ponents when installed. Also, after the brake tubes
are installed on the HCU, ensure all spacer clips are
reinstalled on the brake tubes.
CAUTION: When installing the chassis brake tubes
on the HCU valve block, they must be located cor-
rectly in the valve block to ensure proper ABS oper-
ation. Refer to (Fig. 3) for the correct chassis brake
tube locations.
NOTE: The chassis brake tube attachment locations
to the HCU, are marked on the bottom of the ICU
mounting bracket.
(3) Install the 6 chassis brake tubes into their cor-
rect port locations on the HCU valve block as shown
in (Fig. 3). Tighten the tube nuts to a torque of 17
N´m (145 in. lbs.).
NOTE: Before installing the 24-way connector in the
CAB be sure the seal is properly installed in the
connector.(4) Install the 24-way connector (Fig. 1) on the
CAB using the following procedure. Position the
24-way connector in the socket of the CAB and care-
fully push it down as far as possible. When connector
is fully seated by hand into the CAB socket, push in
the connector lock (Fig. 2). This will pull the connec-
tor into the socket of the CAB and lock it in the
installed position.
NOTE: The CAB wiring harness must be clipped to
the ICU mounting bracket. This will ensure the wir-
ing harness is properly routed and does not contact
the brake tubes or the body of the vehicle.
(5) Clip the cab wiring harness (Fig. 1) to the ICU
mounting bracket.
(6) Install the routing clips (Fig. 9) on the brake
tubes.
(7) Lower the vehicle.
(8) Connect negative cable back on negative post of
the battery.
(9) Bleed the base and ABS hydraulic systems.
Refer to ANTILOCK BRAKE SYSTEM BLEEDING.
(10) Road test vehicle to ensure proper operation
of the base and antilock brake systems.

CLEANING
Drain cooling system and refill with clean water.
Refer to procedures in this section. Run engine with
radiator cap installed until upper radiator hose is
hot. Stop engine and drain water from system. If
water is dirty; fill, run, and drain system again, until
water runs clear.
INSPECTION
After performing a cleaning/flush procedure,
inspect all hoses, clamps and connections for deterio-
ration and leaks. Inspect radiator and heater core for
leaks.
COOLANT
DIAGNOSIS AND TESTING - COOLANT
CONCENTRATION
Coolant concentration should be checked when any
additional coolant was added to system or after a cool-
ant drain, flush and refill. The coolant mixture offers
optimum engine cooling and protection against corrosion
when mixed to a freeze point of -37ÉC (-34ÉF) to -59ÉC
(-50ÉF). The use of a hydrometer or a refractometer can
be used to test coolant concentration.
A hydrometer will test the amount of glycol in a
mixture by measuring the specific gravity of the mix-
ture. The higher the concentration of ethylene glycol,
the larger the number of balls that will float, and
higher the freeze protection (up to a maximum of
60% by volume glycol).

RADIATOR FAN RELAY
DESCRIPTION
The radiator fan relay is a solid state type and is
located on the front bumper reinforcment (Fig. 22).
Refer to WIRING DIAGRAMS for a circuit sche-
matic.
OPERATION
The solid state radiator fan relay is controlled by
the Powertrain Control Module (PCM) by way of a
Pulse Width Modulated (PWM) signal. The relay con-
trol circuit supplies a 12 volt signal to the PCM. The
PCM then pulses the ground circuit to achieve fan on
time. The relay provides a voltage to the fan motors
which is proportional to the pulse width it receives
from the PCM. The duty cycle ranges from 30% for
low speed operation, then ramps-up to 100% for high
speed operation. This fan control system provides
infinitely variable fan speeds, allowing for improved
fan noise, A/C performance, better engine cooling,
and additional vehicle power.
To control operation of the relay, the PCM looks at
inputs from:
²Engine coolant temperature
²A/C pressure transducer
²Ambient temperature from the body controller
²Vehicle speed
²Transmission oil temperature
The PCM uses these inputs to determine when the
fan should operate and at what speed. For further
information on fan operation, (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - OPERATION).
REMOVAL
(1) Open hood.
(2) Disconnect and isolate the battery negative
cable.
(3) Remove the radiator crossmember to front fas-
cia closure panel.
(4) Disconnect the relay electrical connector (Fig.
22).
(5) Remove the rivet attaching the relay to the
front bumper beam (Fig. 22).
(6) Remove the relay.
INSTALLATION
CAUTION: The relay mounting location is designed
to dissipate heat. Ensure the relay is securely
attached to prevent relay ªthermalº shutdown and
relay damage, resulting in possible engine over-
heating.

INSPECTION
Hold the cap in your hand,top side up(Fig. 21).
The vent valve at the bottom of the cap should open.
If the rubber gasket has swollen, preventing the
valve from opening, replace the cap.
Hold the cleaned cap in your hand,upside down.
If any light can be seen between vent valve and the
rubber gasket, replace the cap.Do not use a
replacement cap that has a spring to hold the
vent shut.
A replacement cap must be of the type designed for
coolant reserve systems. This design ensures coolant
return to the radiator.

DIAGNOSIS AND TESTING
If the vehicle is equipped with remote radio
switches located on the backs of the steering wheel
spokes, and the problem being diagnosed is related to
one of the symptoms listed below, be certain to check
the remote radio switches and circuits as described
in this group, prior to attempting radio diagnosis or
repair.
²Stations changing with no remote radio switch
input
²Radio memory presets not working properly
²Volume changes with no remote radio switch
input
²Remote radio switch buttons taking on other
functions
²CD player skipping tracks
²Remote radio switch inoperative.

appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

QUARTER GLASS INTEGRAL
ANTENNA
DESCRIPTION
The quarter glass integral antenna element is
bonded to the right rear quarter glass and is replaced
with the glass assembly only (Fig. 1).
OPERATION
The integral antenna receives RF (Radio Frequen-
cies) and sends them to the antenna module for
amplification.
DIAGNOSIS AND TESTING - QUARTER GLASS
INTEGRAL ANTENNA
The antenna grid pattern is divided into two sepa-
rate patterns. Each terminal connects to a separate
grid pattern, one for AM and the other for FM.
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds. To detect breaks in the
integral antenna elements, the following procedure is
required:
(1) Disconnect the antenna module connector from
the antenna terminals on the glass.
(2) Using an ohmmeter, place a lead on one of the
terminals and check each end of the grid pattern con-
nected to this terminal for continuity. If continuity is
not present, move one lead through the grid in pro-
gression starting at the terminal with the other lead
on the terminal until continuity is lost. Repeat pro-
cedure for the other terminal. A break in the antenna
grid can be repaired using a Mopar Rear Window
Defogger Repair Kit (Part Number 4267922) or
equivalent. (Refer to 8 - ELECTRICAL/HEATED
GLASS/WINDSHIELD GRID - STANDARD PROCE-
DURE).
