SAFETY NOTICE
CAUTION
ALL SERVICE AND REBUILDING INSTRUCTIONS CONTAINED HEREIN ARE
APPLICABLE TO, AND FOR THE CONVENIENCE OF, THE AUTOMOTIVE
TRADE ONLY. All test and repair procedures on components or assemblies in
non-automotive applications should be repaired in accordance with instructions
supplied by the manufacturer of the total product.
Proper service and repair is important to the safe, reliable, operation of all motor vehicles.
The service procedures recommended and described in this publication were developed
for professional servlTe personnel and are effective methods for performing vehicle
repair. Following
these procedures will help assure efficient economical vehicle
performance and service reliability. Some of these service procedures require the use of
special tools designed for specific procedures. These special tools should be used when
recommended throughout this publication.
Special attention should be exercised when working with spring or tension loaded
fasteners and devices such as E-Clips, Circlips, Snap rings, etc., as careless removal
may cause personal injury. Always wear safety goggles whenever working on
vehicles or vehicle components.

It is important to note that this publication contains various Cautions and Warnings.
These should be carefully read in order to minimize the risk of personal injury, or the
possibility that, improper service methods may damage the vehicle or render it unsafe.
It is important to note that these Cautions and Warnings cover only the situations and
procedures Chrysler Motors has encountered and recommended. Chrysler Motors could
not possibly know, evaluate, and advise the service trade of all conceivable ways that
service may *be performed, or of the possible hazards of each. Consequently, Chrysler
Motors has not undertaken any such broad service review. Accordingly, anyone who
uses a service procedure, or tool, that is not recommended in this publication, must assure
oneself thoroughly that neither personal safety, nor vehicle safety, be jeopardized by
the service methods they select.

GENERAL - Technical Features
BASIC CONSTRUCTION
The 4WD vehicles are equipped with 2.OL DOHC
16-valve turbocharged engine and incorporate new
technologies such as full time 4WD of center
differential type with viscous coupling differential
limiting for excellent running stability and excellent
Steering
l Light weight and compact rack and pinion
type for high steering response
l Tilt steering mechanism to give optimum
driving position
\
driving across bad roads, and $-wheel independent
suspension for comfortable riding.
Adopted on 2WD vehicles are 2.OL DOHC 16-valve
engine, MacPherson strut type front suspension
and torsion axle typ.e 3-link rear suspension.
Rear suspension
l Self-aligning double wishbone type suspen-
sion for comfortable ride (4WD)
l Torsion axle type 3 link suspension for
outstanding driving stability (2WD)
l Negative chamber for outstanding steer-
ability during high speed driving
0 Anti-lift geometry for high stability during
braking
l Integral torsional bar type axle beam for
optimum roll stiffness (2WD)
\
Front propeller shaft (3-piece 4-joint type)
l Robro joint to absorb lengthwise and angular
change and prevent transmission of vibrations.
(4WD)
I
Front suspension
The front suspension of McPherson strut type
independent suspension system
l Under steer geometry for outstanding steering
stability
l Negative offset geometry for outstanding stabil-
ity at braking
0 Offset coil springs for comfortable ride
Brakes
l Cross piping dual type proportioning valve
that keeps balanced braking power even at
failure of the hydraulic system.
l Four wheel disc brake system for high
braking power.

GENERAL - Technical Features o-5
ENGINE
The engines are the transverse-mounted engine
especially for front-engine/front-wheeldrive or
front-engine/4-wheel drive models, the 2.OL DOHC
16-valve engine with high-performance, silent-
operation,
low-vibration, low-noise, low-fuel-
consumption features, an engine that fully displays
the most up-todate engine technology.

FEATURES
High performance and low fuel consumption
l The rocker arm reduces the valve-actuation torque as well as fuel consumption.
l Air-intake efficiency improved through the adoption of the optimum air-intake system layout.
l Improved response and fuel consumption has been achieved by electronic control multipoint
fuel injection.
l Water-cooled turbocharger. <Turbo>
Quiet operation
l Noise and vibration have been decreased by the adoption of roller rocker arms.
l Noise generated by the valve mechanism has been decreased by the hydraulic auto lash adjusters.
l Vibrations have been decreased by the adoption of bearing caps with beams which increase the
rigidity of the crankshaft support points.
-
Serviceability
l Complete self-diagnosis functions.
l Enhanced reliability through the adoption of gold-plated connector terminals.
l Use of an auto tensioner achieves maintenance-free, automatic adjustment of timing belt
tension.
l Use of the auto lash adjusters achieves maintenance-free, automatic adjustment of valve clearance
.o The 2coil ignition system without a distributor supplies sufficient ignition energy even during
high speed operation.
