protection. MopartAntifreeze or the equivalent is
recommended for best engine cooling without corro-
sion. When mixed only to a freeze point of -37ÉC
(-35ÉF) to -59ÉC (-50ÉF). If it looses color or becomes
contaminated, drain, flush, and replace with fresh
properly mixed solution.
COOLANT RECOVERY SYSTEM
This system works in conjunction with the radiator
pressure cap to utilize thermal expansion and con-
traction of the coolant to keep the coolant free of
trapped air. The system provides space for expansion
and contraction. Also, the system provides a conve-
nient and safe method for checking and adjusting the
coolant level at atmospheric pressure without remov-
ing the pressure cap. It also provides some reserve
coolant to compensate for minor leaks and evapora-
tion or boiling losses. All vehicles are equipped with
this system (Fig. 2).
Refer to Coolant Level Check, Deaeration, and
Pressure Cap sections for operation and service.
ENGINE THERMOSTAT
The engine thermostat is located on the front of
the engine (radiator side) in the thermostat housing/
engine outlet connector. The thermostat has an air
bleed (vent) located in the flange and a O-ring for
sealing incorporate on it. There is a relief in the ther-
mostat housing/outlet connector for the O-ring.
The engine thermostat is a wax pellet driven,
reverse poppet choke type. It is designed to provide
the fastest warm up possible by preventing leakage
through it and to guarantee a minimum engine oper-
ating temperature of 88 to 93ÉC (192 to 199ÉF). Also,
the thermostat will automatically reach wide open, to
accommodate unrestricted flow to the radiator astemperature of the coolant rises in hot weather to
around 104ÉC (220ÉF). Above this temperature the
coolant temperature is controlled by the radiator, fan,
and ambient temperatureÐnot the thermostat.
A thermostats primary purpose is to maintain
engine temperature in a range that will provide sat-
isfactory engine performance and emission levels
under all expected driving conditions. It also provides
hot water (coolant) for heater performance. It does
this by transferring heat from engine metal and
automatic transmission oil cooler (if equipped) to
coolant, moving this heated coolant to the heater core
and radiator, and then transferring this heat to the
ambient air.
RADIATOR
The radiator is a down-flow type (vertical tubes)
with design features that provide greater strength,
as well as sufficient heat transfer capabilities to keep
the engine coolant within operating temperatures.
The radiator functions as a heat exchanger, using
air flow across the exterior of the radiator tubes. This
heat is then transferred from the coolant and into
the passing air.
The radiator has an aluminum core with plastic
tanks. Although stronger than brass, plastic tanks
are subject to damage by impact. Always handle radi-
ator with care.
RADIATOR COOLING FAN MODULE
The radiator cooling fan is a single speed electric
motor driven fan. The fan module includes an electric
motor, fan blade, and a support shroud that is
attached to the radiator (Fig. 3).

GENERAL INFORMATION
INTRODUCTION
The purpose of the dash gauges and indicator
lamps is to keep the driver informed about the oper-
ating condition of the vehicle. If an abnormal condi-
tion occurs, the driver is informed by indicator lamp.
The driver can seek service before damage occurs.
Indicator lamps use ON/OFF switch functions for
operation, while gauges use a sending unit or sensor.
The Instrument Panel can be removed as an
assembly after a few part are removed to allow
access to the retaining bolts. There is one self-align-
ing bulkhead connector on the left underside of the
instrument panel replacing most of the main harness
connectors. Once removed, the instrument panel can
be serviced for replacement. Most of the parts of the
instrument panel can be replaced individually with-
out removing the complete instrument panel assem-
bly.

MULTIPLE/INDIVIDUAL GAUGES INOPERATIVE
Test speedometer, tachometer and other gauges for
malfunction:
(1) Remove the cluster. Refer to Cluster Removal
and Installation.
(2) Check for ignition voltage at Pin 15 of the clus-
ter wire harness connector (Fig. 5). Check for battery
voltage at Pin 21 of the connector. If no voltage,
repair as necessary.
(3) Check Pin 10 of the connector for continuity to
ground. If no ground, repair as necessary.
(4) If the voltage and ground are OK, and the pins
or the connectors are not distorted, replace the
instrument cluster.
(5) Install cluster. Refer to Instrument Cluster
Removal and Installation in this section.
SERVICE PROCEDURES
INSTRUMENT CLUSTER SELF-DIAGNOSTICS
To put the cluster in self-diagnostics mode press
the trip reset button down and then turn the ignition
to the RUN position simultaneously, then release the
button. The gauges will increment to selected stoops
and all indicators will light with the exception of the
turn signals, high beam, and fog lamp indicators.
The oil lamp will come on when the ignition is
turned ON and the engine is OFF.

DESCRIPTION AND OPERATION
REAR WINDOW DEFOGGER SYSTEM
For proper operation of the Rear Window Defogger
system refer to the Owner's Manual.
The system consists of a rear glass with two verti-
cal bus bars and a series of electrically connected
grid lines fired on the inside surface (Fig. 1). A con-
trol switch and a timing circuit are combined into a
single assembly.
Circuit protection is provided by a cartridge fuse
located in the Power Distribution Center (PDC) for
the heated grid circuit, and by a fuse in the fuse
block for the control circuit.
When the switch is turned to the ON position, cur-
rent is directed to the rear defogger grid lines. The
heated grid lines heat the rear glass to clear the sur-
face of fog or frost.CAUTION: Grid lines can be damaged or scraped
off with sharp instruments. Care should be taken in
cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents
or hot water used with rags or toweling is recom-
mended.
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch is a control
switch and timing circuit integrated into a single
panel mounted assembly (Fig. 2). Actuating the
switch energizes the circuit which allows current to
flow through the grid lines. Upon initial actuation for
approximately eight to ten minutes, or until either
the switch or ignition is turned off. An indicating
lamp illuminates a Light Emitting Diode (LED)
inlaid in the control switch.
