should be above ADD mark. Add fluid only if level is
below ADD mark on dipstick when transaxle is
warm.The automatic transaxle does not require periodic
maintenance when used for general transportation. If
the vehicle is subjected to severe service conditions,
the automatic transaxle will require fluid/filter
change and band adjustments every 24 000 km
(15,000 miles). For additional information, refer to
Severe Service paragraph and Lubrication and Main-
tenance Schedules in General Information section of
this group. The fluid and filter should be changed
when water contamination is suspected. If fluid has
foamy or milky appearance, it is probably contami-
nated. If the fluid appears brown or dark and a foul
odor is apparent, the fluid is burned, transaxle re-
quires maintenance or service. A circular magnet lo-
cated in the transaxle pan, collects metallic particles
circulating in the oil. For proper diagnostic and ser-
vice procedures, refer to Group 21, Automatic Tran-
saxle.
SELECTING AUTOMATIC TRANSAXLE FLUID
Chrysler Corporation recommends Mopar ATF Plus
(automatic transmission fluid type 7176) be used to
add to or replace automatic transaxle fluid. If ATF
Plus is not available use Mopar Dexron II tAuto-
matic Transmission Fluid or equivalent.
DRIVE SHAFT CV AND TRIPOD JOINT BOOTS
The front drive shaft constant velocity and tripod
joint boots (Fig. 5) should be inspected when other
under vehicle service is performed. Inspect boots for
cracking, tears, leaks or other defects. If service re-
pair is required, refer to Group 2, Suspension.
FRONT WHEEL BEARINGS
The front wheel bearings are permanently sealed,
requiring no lubrication. For proper diagnostic and
service procedures refer to Group 2, Suspension.
TIRES
The tires should be inspected at every engine oil
change for proper inflation and condition. The tires
should be rotated at the distance intervals described
in the Lubrication and Maintenance Schedules of the
General Information section in this group. For tire
inflation specifications refer to the Owner's Manual.
A Tire Inflation sticker is located in the driver door
opening. For proper diagnostic procedures, see Group
22, Wheels and Tires.Fig. 2 3-speed Automatic Transaxle Fill hole

mount have been loosened for any reason, or if vehicle
has experienced front structural damage, driveshaft
lengths must be checked and corrected, if required. A
shorter than required driveshaft length can result in ob-
jectionable noise. A longer than required driveshaft
length may result in potential damage.
Use of the following procedure will ensure satisfac-
tory driveshaft engagement under all normal vehicle
operating conditions. (1) The vehicle must be completely assembled.
Front wheels must be properly aligned and in the
straight ahead position. The vehicle must be in a po-
sition so that the full weight of the body is distrib-
uted to all four tires. A platform hoist, or front end
alignment rack, is recommended.
(2) Using a tape measure or other suitable measuring
device. Measure the direct distance from the inner edge of the outboard boot to the inner edge of the inboard
boot on both driveshafts. This measurement must be
taken at the bottom (six o'clock position) of the drive-
shafts (Fig. 1).
Note that the required dimension varies with car-line,
engine, transaxle, and driveshaft manufacturer (Fig. 2).
(3) If the lengths of both shafts are within the
range specified, no further action is required. If either left or right driveshaft length is not
within the specified range. Refer to Group 09, Engine
Removal and Installation to properly position engine
according to specified driveshaft lengths.
(4) If proper driveshaft lengths cannot be achieved
within the travel limits available in the slotted engine
mounts. Check for any condition that could effect the
side to side position of the measurement locations (e.g.,
engine support brackets, siderail alignment, etc.).
(5) After ensuring proper driveshaft lengths the
transmission shift linkage must be adjusted to en-
sure proper operation. Refer to Transaxle, Group 21.

INSTALLING MASTER CYLINDER
Position master cylinder over studs of power brake
unit, align push rod with master cylinder piston. Install the master cylinder to power brake unit
mounting nuts (Fig. 4) and tighten to 28 N Im (250 in.
lbs.) torque. Connect brake tubes to master cylinder primary and
secondary ports. Tighten fittings to 17 N Im (145 in-
.lbs.) torque.
POWER BRAKES
GENERAL INFORMATION
All vehicles, except non turbo charged AP bodies,
equipped with manual transmissions use a 205 mm
tandem booster. The non turbo charged manual trans-
mission equipped AP body application use a 230 mm
non-tandem booster. The purpose of the vacuum operated power brake
booster. Is to reduce the amount of force applied to the
brake pedal by the drivers foot. To obtain the required
hydraulic pressure in the brake system to stop the
vehicle. The power brake booster can be identified if required,
by the tag attached to the body of the booster assembly
(Fig. 1). This tag contains the following information.
The production part number of the power booster
assembly, the date it was built and who manufactured
it. The power brake booster assembly is not a
repairable part and must be replaced as a com-
plete unit if it is found to be faulty in any way.
The power booster vacuum check valve is not
repairable but can be replaceable as an assembly. The power brake booster is vacuum operated. The
vacuum is supplied from the intake manifold on the
engine through the power brake booster check valve
(Fig. 2). As the brake pedal is depressed, the power boosters
input rod moves forward. This opens and closes valves
in the power booster, creating a vacuum on one side of
a diaphragm and allowing atmospheric pressure to enter on the other. This difference in
pressure forces the output rod of the power booster
out against the primary piston of the master cylin-
der. As the pistons in the master cylinder move for-
ward this creates the hydraulic pressure in the brake
system. Different systems and engine combinations require
different vacuum hose routings.

GENERAL INFORMATION
Throughout this group, references may be made to
a particular vehicle by letter or number designation.
A chart showing the breakdown of these designations
is included in the Introduction Section at the front of
this service manual. The clutch used in all models are a single, dry disc
type with no adjustment for wear being provided in
the clutch itself. The clutch pedal is connected to the release shaft
through a cable and lever. The upper end of the clutch pedal pivots in the
pedal bracket on two nylon bushings. These bushings
do not require periodic lubrication.
CLUTCH CHATTER COMPLAINTS
For all clutch chatter complaints, do the following:
(1) Check for loose, misaligned, or broken engine
and transmission mounts. If present, they should be
corrected at this time. Test vehicle for chatter. If
chatter is gone, there is no need to go any further. If
chatter persists: (2) Check to see if clutch cable routing is correct
and operates smoothly. (3) Check for loose connections in drive train. Cor-
rect any problems and determine if clutch chatter
complaints has been satisfied. If not, (4) Remove transaxle. See Group 21, Manual Tran-
saxle, for procedure. (5) Check to see if the release bearing is sticky or
binding. Replace bearing, if needed. (6) Check linkage for excessive wear on bushings.
Replace all worn parts. A small amount of bearing
grease between the release shaft bushings and the
shaft is beneficial, but not required. (7) Check flywheel and clutch pressure plate for
contamination (dirt, oil) or scored. Replace flywheel
and/or pressure plate, if required. (8) Check to see if the clutch disc hub splines are
damaged. Replace with new disc. (9) Check input shaft splines for damage. Replace
if necessary. (10) Check for uneven wear on clutch fingers.
EXCESSIVE CLUTCH SPIN TIME/CLASH INTO
REVERSE COMPLAINTS
For all excessive clutch spin time/clash into reverse
complaints, do the following: (1) Depress clutch pedal to floor and hold. After
three seconds, shift to reverse. If clash is present,
clutch has excessive spin time. (2) Remove transaxle. See Group 21, Manual Tran-
saxle, for procedure. (3) Check the input shaft spline, clutch disc splines
and release bearing for dry rust. If present, clean
rust off and apply a light coat of bearing grease to
the input shaft splines. Apply grease on the input
shaft splines only where the clutch disc slides. (4) Check to see if the clutch disc hub splines are
damaged, replace with new disc if required. (5) Check the input shaft for damaged splines. Re-
place as necessary. (6) Check for excessive clutch disc runout or
warpage. (7) Install clutch assembly and transaxle.
CLUTCH CABLE MECHANISM
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 pedal. The preload spring main-
tains tension on the cable. This tension keeps the
clutch release bearing continuously loaded against
the fingers of the clutch cover assembly. When the pedal is depressed, teeth on the adjuster
and the positioner engage and pull the release cable.
A spring located behind the adjuster ensures proper
tooth engagement. When the pedal is released, the adjuster contacts
the bumper. This separates the adjuster and posi-
tioner teeth, allowing the preload spring to function.

GENERAL INFORMATION
Throughout this group, references may be made to
a particular vehicle by letter or number designation.
A chart showing the breakdown of these designations
is included in the Introduction Section at the front of
this service manual.
COOLING SYSTEM
The cooling system consists of an engine cooling
module, thermostat, coolant, a water pump to circu-
late the coolant. The engine cooling module may con-
sist of a radiator, electric fan motor, shroud, radiator
pressure cap, coolant reserve system, transmission oil
cooler, hoses, clamps, air condition condenser, trans-
mission oil lines and charge air cooler.
² When Engine is cold: Thermostat is closed, cooling
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 ra-
diator. 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 auto-
matic 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 2.2L and 2.5L engine
equipped vehicles are shown in (Fig 1). Turbocharged
equipped engines coolant routing and plumbing are
shown in (Fig 2). The 3.0L engine coolant routing is
shown in (Fig 3). The 3.3L and 3.8L engine coolant
routing is shown in (Fig 5).

WATER PUMPS
A quick test to tell whether or not the pump is
working is to see if the heater warms properly. A
defective pump will not be able to circulate heated
coolant through the long heater hose. The water pump on all models can be replaced
without discharging the air conditioning system.
WATER PUMPÐ2.2/2.5L ENGINE
The 2.2/2.5L engine water pump has a diecast alu-
minum body and housing with a stamped steel impel-
ler. The 2.2/2.5L pump uses an O-ring gasket between
body and housing. The assembly bolts directly to the
block. Cylinder block to water pump sealing is provided
by a rubber O-ring.
REMOVAL (1) Drain cooling system. Refer to Draining Cooling
System in this group. (2) If equipped with air conditioning, see Solid
Mount Accessory Bracket in (Standard Service Proce-
dures) Group 9, Engine: (a) Remove air conditioning compressor and gen-
erator from solid mount bracket and set aside.It is
not necessary to discharge the a/c system. (b) Remove solid mount bracket.
(3) If the vehicle is not equipped with air condi-
tioning, remove generator and mounting bracket. (4) Disconnect lower radiator and heater hoses
from pump. (5) Remove water pump attaching screws to engine
(Fig. 1). Turbo III has a spacer between the water
pump and block on the lower screw.
DISASSEMBLY (1) Remove three screws holding pulley to water
pump. (2) Remove nine screws holding water pump body
to housing. Remove the pump body from housing
(Fig. 2). (3) Clean gasket surfaces on water pump housing
and engine block. (4) Remove and discard O-ring gaskets and clean
O-ring grooves.
