INSTALLATION
1. Position the slave cylinder assembly to the tran-
saxle deck and secure with the nut and washer
assemblies (2) and tighten to specifications (Fig. 14).
2. Make sure the slave cylinder pushrod is prop-
erly seated in the cup end of the clutch release lever.
3. Connect the quick connect coupling. Refer to the
ªQuick Connect Couplingº removal and installation
procedure in this section.
MODULAR CLUTCH ASSEMBLY (2.0L AND 2.4L
GASOLINE)
The transaxle must be removed to service the mod-
ular clutch assembly and components (Fig. 17). Refer
to Group 21 for the ªA-558 Manual Transaxleº
removal procedure.
CLUTCH ASSEMBLY (2.5L DIESEL)
The transaxle must be removed to service the
clutch disc assembly and components.
REMOVAL
(1) Remove the transaxle, refer to Group 21, Tran-
saxle.
(2) Install universal clutch alignment tool into the
clutch assembly (this will prevent the clutch from
inadvertently being dropped).
(3) To avoid distortion of the pressure plate,
remove the clutch pressure plate bolts a few turns at
a time. Use a crisscross pattern until all bolts are
loosened.
(4) Carefully remove the clutch pressure plate and
disc (Fig. 18).To service the flywheel, refer to Group 9, Engine.
INSPECTION
Inspect for oil leakage through engine rear main
bearing oil seal and transaxle input shaft seal. If
leakage is noted, it should be corrected at this time.
The friction faces of the flywheel and pressure
plate should not have:
²Excessive discoloration
²Burned areas
²Small cracks
²Deep grooves
²Ridges
Replace parts as required.
CAUTION: Do not polish flywheel to a mirror like
surface. Clean the flywheel face with medium sand-
paper (80-160 grade), then wipe the surface with
mineral spirits. If the surface is severely scored,
heat checked, or warped, replace the flywheel.
CAUTION: Do not flat-machine the flywheel face.
The surface profile is slightly tapered and has a
0.30 mm step.
The disc assembly should be handled without
touching the facings. Replace disc if the facings show
evidence of grease or oil soakage, or wear to within
less than .38 mm (.015 inch) of the rivet heads. The
splines on the disc hub and transaxle input shaft
should be a snug fit without signs of excessive wear.
Metallic portions of disc assembly should be dry and
clean, and not been discolored from excessive heat.
Each of the arched springs between the facings
should not be broken and all rivets should be tight.
Wipe the friction surface of the pressure plate with
mineral spirits.
Using a straight edge, check clutch cover (pressure
plate) for flatness. The clutch cover (pressure plate)

REMOVAL AND INSTALLATION (Continued)

friction area should be slightly concave, with the
inner diameter 0.02 mm to 0.1 mm (.0008 in. to .0039
in.) below the outer diameter. It should also be free
from discoloration, burned areas, cracks, grooves, or
ridges.
Using a surface plate, test cover for flatness. All
sections around attaching bolt holes should be in con-
tact with surface plate within .015 inch.
The cover should be a snug fit on flywheel dowels.
If the clutch assembly does not meet these require-
ments, it should be replaced.
INSTALLATION
(1) Position the clutch and pressure plate onto the
flywheel.
(2) Insert the universal clutch alignment tool into
the clutch disc.
(3) To avoid distortion of the pressure plate, bolts
should be tightened a few turns at a time (Fig. 19).
Use a crisscross pattern until all bolts are seated.
Tighten pressure plate bolts to 27 N´m (20 ft. lbs.).
(4) Remove the universal clutch alignment tool.
(5) Install the transaxle, refer to Group 21, Tran-
saxle.
(6) Fill transaxle to the proper level with the spec-
ified lubricant.
(7) While the vehicle is elevated slightly, run the
transaxle through all the forward gears. Apply
brakes and shift into reverse. Run the transaxle
through reverse gear.
(8) Check the transaxle for leaks and recheck the
level of the transaxle lubricant.
CLUTCH RELEASE BEARING AND FORK
Remove the transaxle from the vehicle. See Group
21, for removal and installation procedures.
REMOVAL
(1) Remove clutch release shaft E-clip (Fig. 20).
(2) Remove the clutch release shaft and then slide
the fork and bearing assembly off the bearing pilot
(Fig. 21).

REMOVAL AND INSTALLATION (Continued)

(3) Remove the fork from the bearing thrust plate
(Fig. 22).
(4) Examine the condition of the bearing. It is pre-
lubricated and sealed and should not be immersed in
oil or solvent.
(5) The bearing should turn smoothly when held in
the hand under a light thrust load. A light drag
caused by the lubricant fill is normal. If the bearing
is noisy, rough, or dry, replace the complete bearing
assembly with a new bearing.
(6) The bearing has a plastic sleeve pre-lubricated
at assembly. Wipe out the old grease. Refill the sleeve
cavities and coat the inner surface with multipurpose
grease. If the liner is cracked or worn, replace the
bearing assembly.
(7) Check the condition of the spring clips. If the
clips are broken or distorted, replace the bearing
assembly.
INSTALLATION
(1) Before assembling the fork, lubricate the
rounded thrust pads and the spring clip cavities with
multipurpose grease.
(2) Assemble the fork to the bearing by sliding the
thrust pads under the spring clips. Be careful to
avoid distorting the spring clips. These clips prevent
the bearing thrust plate from rotating with the bear-
ing.
(3) Slide the bearing and fork assembly onto the
input shaft bearing retainer.
(4) Position the release shaft bushings in the hous-
ing and install the release shaft. A small amount of
bearing grease between the release shaft bushing
and the shaft is beneficial but not required. Install
the retainer clip in the shaft groove near the large
bushing.
(5) Install the release lever and retaining clip on
the outer end of the release shaft.
CLEANING AND INSPECTION
CLUTCH CONTAMINATION
Fluid contamination is a frequent cause of clutch
malfunctions. Oil, grease, water, or other fluids on
the clutch contact surfaces will cause faulty opera-
tion.
During inspection, note if any components are con-
taminated. Look for evidence of oil, grease, or water/
road splash on clutch components.
OIL CONTAMINATION
Oil contamination indicates a leak at the rear main
seal and/or transaxle input shaft. Oil leaks produce a
residue of oil on the transaxle housing interior, clutch
cover and flywheel. Heat buildup caused by slippage
can bake the oil residue onto the components. This
glaze-like residue ranges in color from amber to
black.
GREASE CONTAMINATION
Grease contamination is usually a product of over-
lubrication. During clutch service, apply only a small
amount of grease to the input shaft splines. Excess
grease may be thrown off during operation, contami-
nating the disc.
ROAD SPLASH/WATER CONTAMINATION
Road splash contamination is usually caused by
driving the vehicle through deep water puddles.
Water can be forced into the clutch housing, causing
clutch components to become contaminated. Facing of
disc will absorb moisture and bond to the flywheel
and/or, pressure plate, if vehicle is allowed to stand
for some time before use. If this condition occurs,
replacement of clutch assembly may be required.
Drive the vehicle until normal clutch operating tem-
perature has been obtained. This will dry off disc
assembly, pressure plate, and flywheel.
CLEANING PRECAUTIONS
Condensation from steam vapors tend to accumu-
late on the internal clutch mechanism when the vehi-
cle is steam cleaned. Facing of disc will absorb
moisture and will bond to flywheel and/or pressure
plate, if vehicle is allowed to stand for some time
before use. If this condition occurs, it may require
replacement of clutch assembly. After cleaning, drive
the vehicle to its normal clutch operating tempera-
ture. This will dry off disc assembly, pressure plate,
and flywheel.

ADJUSTMENTS
CLUTCH CABLE Ð LHD
The manual transaxle clutch release system has a
unique self-adjusting mechanism to compensate for
clutch disc wear. This adjuster mechanism is located
within the clutch cable assembly. The preload spring
maintains tension on the cable. This tension keeps
the clutch release bearing continuously loaded
against the fingers of the clutch cover assembly.
ADJUSTER MECHANISM FUNCTION CHECK Ð
LHD
(1) With slight pressure, pull the clutch release
lever end of the cable to draw the cable taut. Push
the clutch cable housing toward the dash panel (With
less than 20 lbs. of effort, the cable housing should
move 30-50mm.). This indicates proper adjuster
mechanism function. If the cable does not adjust,
determine if the mechanism is properly seated on the
bracket.
(2) If the adjust mechanism functions properly,
route cable to the transaxle.
(3) Insert cable into transaxle and through clutch
release lever. Ensure the cable is routed through the
smaller hole in the transaxle deck (Fig. 10).
(4) Pull down on cable and insert cable retaining
clip onto clutch cable end.
(5) Check clutch pedal position switch operation.
CLUTCH PEDAL POSITION SWITCH
The clutch pedal position switch is mounted to a
bracket located behind the clutch pedal. The switch
is held in place by four plastic wing tabs.
The clutch pedal position switch IS NOT adjust-
able. The pedal blade contacts the switch in the down
position.

GENERAL INFORMATION
ACCESSORY DRIVE BELTS
The accessory drive system utilizes two different
style of drive belts. The conventional V-belt and the
Poly-V belt are used to drive the generator, air con-
ditioning compressor, power steering pump and waterpump. Satisfactory performance of these belts
depends on belt condition and proper belt tension.
Belt tensioning should be performed with the aid of a
Burroughs gauge Special Tool C-4162. Because of
space limitations in the engine compartment, the use
of the gauge may be restricted. Raise the vehicle on a
hoist and then remove the splash shield to gain
access to the drive belts.
NSCOOLING SYSTEM 7 - 1

COOLING SYSTEM
The cooling system has a radiator, coolant, electric fan
motor, shroud, pressure cap, thermostat, coolant reserve
system, transmission oil cooler, a water pump to circulate
the coolant, hoses, and clamps to complete the circuit.
²When Engine is cold: thermostat is closed, cool-
ing system has no flow through the radiator. The
coolant bypass flows through the engine only.
²
When Engine is warm: thermostat is open, cooling
system has bypass flow and coolant flow through radia-
tor.
Its primary purpose is to maintain engine temper-
ature in a range that will provide satisfactory engine
performance and emission levels under all expected
driving conditions. It also provides hot water (cool-
ant) for heater performance and cooling for automatic
transmission oil. It does this by transferring heat
from engine metal to coolant, moving this heated
coolant to the radiator, and then transferring this
heat to the ambient air.
Coolant flow circuits for 2.4L and 3.3/3.8L engines
are shown in (Fig. 1), and 3.0L engine coolant rout-
ing is shown in (Fig. 2)

7 - 2 COOLING SYSTEMNS
GENERAL INFORMATION (Continued)

COOLANT RECOVERY SYSTEM (CRS)
This system works with the radiator pressure cap
to use thermal expansion and contraction of the cool-
ant to keep the coolant free of trapped air. Provides a
convenient and safe method for checking coolant
level and adjusting level at atmospheric pressure
without removing the radiator pressure cap. It also
provides some reserve coolant to cover deaeration
and evaporation or boiling losses. All vehicles are
equipped with this system and take various shapes
and forms. (Fig. 3) shows a typical system in the typ-
ical location.
See Coolant Level Service, and Deaeration, and
Pressure Cap sections for operation and service.
AUTOMATIC TRANSMISSION OIL COOLERÐ2.4L
Oil cooler is internal oil to coolant type, mounted
in the radiator left tank (Fig. 4). Rubber oil lines feed
the oil cooler and the automatic transmission. Use
only approved transmission oil cooler hose. Since
these are molded to fit space available, molded hoses
are recommended.
ENGINE THERMOSTAT
The engine cooling thermostats are a wax pellet
driven, reverse poppet choke type. They are designed
to provide the fastest warm up possible by prevent-
ing leakage through them and to guarantee a mini-
mum engine operating temperature of 88 to 93ÉC
(192 to 199ÉF). They also automatically reach wide
open so they do not restrict flow to the radiator as
temperature of the coolant rises in hot weather to
around 104ÉC (220ÉF). Above this temperature the
coolant temperature is controlled by the fan, the
radiator, and the ambient temperature, not the ther-
mostat.
WATER PUMPS
A quick test to tell whether the pump is working is
to see if the heater warms properly. A defective pump
can not circulate heated coolant through the long
heater hose.The water pump on all models can
be replaced without discharging the air condi-
tioning system.
COOLANT
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves. Cool-
ant then carries this heat to the radiator, where the
tube/fin assemblies of these components can give it
up to the air.
The use of aluminum cylinder heads, intake mani-
folds, and water pumps requires special corrosion
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 loses color or becomes
contaminated, drain, flush, and replace with fresh
properly mixed solution.
CAUTION: Do not use well water, or suspect water
supply in cooling system. A 50/50 ethylene glycol
and distilled water mix is recommended.
RADIATOR
The radiators are cross-flow types (horizontal
tubes) with design features that provide greater
strength along with sufficient heat transfer capabili-

Fig. 4 Automatic Transmission Oil Cooler
NSCOOLING SYSTEM 7 - 3
GENERAL INFORMATION (Continued)

ties to keep the engine satisfactorily cooled (Fig. 5),
(Fig. 6), (Fig. 7) and (Fig. 8).
CAUTION: Plastic tanks, while stronger then brass
are subject to damage by impact, such as wrenches
etc., or by excessive torque on hose clamps.
If the plastic tank is damaged, replace the radia-
tor.
RADIATOR PRESSURE CAP
The radiator is equipped with a pressure cap that
releases excessive cooling system pressure; maintain-
ing a range of 97-124 kPa (14-18 psi).
The cooling system will operate at higher than
atmospheric pressure. The higher pressure raises thecoolant boiling point thus, allowing increased radia-
tor cooling capacity.
There is also a vent valve in the center of the cap.
This valve also opens when coolant is cooling and
contracting allowing coolant to return to radiator
from coolant reserve system tank by vacuum through
connecting hose.If valve is stuck shut, or the
coolant recovery hose is pinched, the radiator
hoses will be collapsed on cool down. Clean the
vent valve (Fig. 9) and inspect coolant recovery
hose routing, to ensure proper sealing when
boiling point is reached.
The gasket in the cap seals the filler neck, so that
vacuum can be maintained, allowing coolant to be
drawn back into the radiator from the reserve tank.

7 - 4 COOLING SYSTEMNS
GENERAL INFORMATION (Continued)

If the gasket is dirty or damaged, a vacuum
may not be achieved, resulting is loss of coolant
and eventual overheating due to low coolant
level in radiator and engine.
ENGINE BLOCK HEATER
The engine block heater is available as an optional
accessory on all models. The heater is operated by
ordinary house current (110 Volt A.C.) through a
power cord located behind the radiator grille. This
provides easier engine starting and faster warm-up
when vehicle is operated in areas having extremely
low temperatures. The heater is mounted in a core
hole (in place of a core hole plug) in the engine block,
with the heating element immersed in coolant.

GENERAL INFORMATION (Continued)

DESCRIPTION AND OPERATION
WATER PIPESÐ3.0L ENGINE
The 3.0L engine uses metal piping beyond the
lower radiator hose to route (suction) coolant to the
water pump, which is located in the V of the cylinder
banks (Fig. 10).
These pipes are provided with inlet nipples for
thermostat bypass and heater return coolant hoses,
and brackets for rigid engine attachment. The pipes
employ O-rings for sealing at their interconnection
and to the water pump (Fig. 10).
COOLANT PERFORMANCE
Performance is measurable. For heat transfer pure
water excels (Formula = 1 btu per minute for each
degree of temperature rise for each pound of water).
This formula is altered when necessary additives to
control boiling, freezing, and corrosion are added as
follows:
²Pure Water (1 btu) boils at 100ÉC (212ÉF) and
freezes at 0ÉC (32ÉF)
²100 percent Glycol (.7 btu) can cause a hot
engine and detonation and will lower the freeze point
to -22ÉC (-8ÉF).
²50/50 Glycol and Water (.82 btu) is the recom-
mended combination that provides a freeze point of
-37ÉC (-35ÉF). The radiator, water pump, engine
water jacket, radiator pressure cap, thermostat, tem-
perature gauge, sending unit and heater are all
designed for 50/50 glycol.CAUTION: Do not use well water, or suspect water
supply in cooling system. A 50/50 ethylene glycol
and distilled water mix is recommended.
Where required, a 56 percent glycol and 44 percent
water mixture will provide a freeze point of -59ÉC
(-50ÉF).
CAUTION: Richer mixtures cannot be measured
with field equipment. This can lead to problems
associated with 100 percent glycol.
RADIATOR HOSES AND CLAMPS
WARNING: IF VEHICLE HAS BEEN RUN
RECENTLY, WAIT 15 MINUTES BEFORE WORKING
ON VEHICLE. RELIEVE PRESSURE BY PLACING A
SHOP TOWEL OVER THE CAP AND WITHOUT
PUSHING DOWN ROTATE IT COUNTERCLOCKWISE
TO THE FIRST STOP. ALLOW FLUIDS AND STEAM
TO ESCAPE THROUGH THE OVERFLOW TUBE.
THIS WILL RELIEVE SYSTEM PRESSURE
The hoses are removed by using constant tension
clamp pliers to compress the hose clamp.
A hardened, cracked, swollen or restricted hose
should be replaced. Do not damage radiator inlet and
outlet when loosening hoses.
Radiator hoses should be routed without any kinks
and indexed as designed. The use of molded hoses is
recommended.
Spring type hose clamps are used in all applica-
tions. If replacement is necessary replace with the
original MOPARtequipment spring type clamp.
WATER PUMPÐ2.4L ENGINE
The water pump has a diecast aluminum body and
housing with a stamped steel impeller. The water
pump bolts directly to the block. Cylinder block to
water pump sealing is provided by a rubber O-ring.
The water pump is driven by the timing belt. Refer
to Timing Belt in Group 9, Engine for component
removal providing access to water pump.
WATER PUMPÐ3.0L ENGINE
The pump bolts directly to the engine block, using
a gasket for pump to block sealing (Fig. 11). The
pump is serviced as a unit.
The water pump is driven by the timing belt. See
Timing Belt in Group 9, Engine for component
removal providing access to water pump.
