WHEEL & TIRE SPECIFICATIONS
TIRE REPLACEMENT
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for wear and
correct inflation pressure. Chrysler strongly recommends that you use
tires equivalent to the originals in quality and performance when
replacement is needed. Failure to use equivalent replacement tires may
adversely affect the safety, handling and ride of your vehicle. We
recommend that you contact your original equipment tire dealer on any
questions you may have on tire specifications or capability.

GENERAL INFORMATION
METRIC CONVERSIONS
METRIC CONVERSIONS
Metric conversions are making life more difficult for the
mechanic. In addition to doubling the number of tools required,
metric-dimensioned nuts and bolts are used alongside English
components in many new vehicles. The mechanic has to decide which tool
to use, slowing down the job. The tool problem can be solved by trial
and error, but some metric conversions aren't so simple. Converting
temperature, lengths or volumes requires a calculator and conversion
charts, or else a very nimble mind. Conversion charts are only part of
the answer though, because they don't help you "think" metric, or
"visualize" what you are converting. The following examples are
intended to help you "see" metric sizes:
LENGTH
Meters are the standard unit of length in the metric system.
The smaller units are 10ths (decimeter), 100ths (centimeter), and
1000ths (millimeter) of a meter. These common examples might help you
to visualize the metric units:
* A meter is slightly longer than a yard (about 40 inches).
* An aspirin tablet is about one centimeter across (.4 inches).
* A millimeter is about the thickness of a dime.
VOLUME
Cubic meters and centimeters are used to measure volume, just
as we normally think of cubic feet and inches. Liquid volume
measurements include the liter and milliliter, like the English quarts
or ounces.
* One teaspoon is about 4 cubic centimeters.
* A liter is about one quart.
* A liter is about 61 cubic inches.
WEIGHT
The metric weight system is based on the gram, with the most
common unit being the kilogram (1000 grams). Our comparable units are
ounces and pounds:
* A kilogram is about 2.2 pounds.
* An ounce is about 28 grams.
TORQUE
Torque is somewhat complicated. The term describes the amount
of effort exerted to turn something. A chosen unit of weight or force
is applied to a lever of standard length. The resulting leverage is
called torque. In our standard system, we use the weight of one pound
applied to a lever a foot long, resulting in the unit called a foot-
pound. A smaller unit is the inch-pound (the lever is one inch long).
Metric units include the meter kilogram (lever one meter long
with a kilogram of weight applied) and the Newton-meter (lever one

CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
INTRODUCTION
Removal, overhaul and installation procedures are covered in
this article. If component removal and installation is primarily an
unbolt and bolt-on procedure, only a torque specification may be
furnished.
COMPUTERIZED ENGINE CONTROLS
POWERTRAIN CONTROL MODULE (PCM)
Removal & Installation
1) Disconnect negative battery cables. Disconnect electrical
connectors from PCM. The PCM is located at passenger's side rear
corner of engine compartment, on the firewall. See Fig. 1. Remove
mounting bolts and PCM.
2) To install, reverse removal procedure. Tighten mounting
bolts to specification. See TORQUE SPECIFICATIONS.

INTERCOOLER
NOTE: Intercooler may also be referred to as charge air cooler.
CAUTION: If vehicle had a turbocharger failure, or for any reason oil
was discharged into the intercooler, intercooler must be
removed and cleaned.
Removal
1) Remove front bumper. Remove front support bracket located
above center of intercooler. On A/C-equipped models, discharge A/C
system using approved refrigerant recovery/recycling equipment.
2) Disconnect and plug hoses and openings at condenser.
Remove condenser-to-intercooler screws and nuts. Remove condenser from
front of intercooler. Plug all openings on condenser.
3) On all models, remove intercooler inlet and outlet ducts.
See Fig. 2 . Remove intercooler bolts. Pivot intercooler forward and
upward to remove.
Inspection & Cleaning
1) Inspect intercooler for damaged fins or cracks. Replace
intercooler if damaged.
CAUTION: DO NOT use caustic cleaners to clean intercooler, or
intercooler may be damaged.
2) If intercooler cleaning is required, flush intercooler
with a non-caustic solvent in the opposite direction of normal
airflow. Use soft-faced hammer to lightly tap on end tanks on
intercooler to dislodge any trapped material.
3) Continue flushing intercooler until all material is
removed from intercooler. Use light to inspect inside of intercooler
for remaining material.
4) Once intercooler is clean, wash intercooler with soap and
hot water to remove remaining solvent. Once remaining solvent is
removed, use clean water to rinse intercooler. Blow compressed air
into intercooler in the opposite direction of the normal airflow until
intercooler is dry.
Installation
To install, reverse removal procedure. Tighten fasteners to
specification. See TORQUE SPECIFICATIONS. On A/C-equipped models,
evacuate and charge A/C system.

TURBOCHARGER
Page 924 of 1691
CAUTION: If turbocharger failure exists, intercooler must be cleaned.
See INTERCOOLER under AIR INDUCTION SYSTEMS.
Removal
1) Disconnect negative battery cables. Disconnect air inlet
tube and exhaust pipe from turbocharger. Disconnect intercooler inlet
duct from turbocharger. See Fig. 2.
2) Disconnect and plug turbocharger oil supply line and
turbocharger oil drain line at turbocharger. Remove turbocharger
retaining nuts, turbocharger and gasket from exhaust manifold. Plug
all air intake openings.
Installation
1) Apply anti-seize compound on turbocharger mounting studs.
Using NEW gasket, install turbocharger. Install and tighten
turbocharger retaining nuts to specification. See TORQUE
SPECIFICATIONS.
2) Using NEW gasket, install turbocharger oil drain line on
turbocharger. Install and tighten turbocharger oil drain line bolts to
specification. See TORQUE SPECIFICATIONS.
CAUTION: Turbocharger must be pre-lubricated by pouring clean engine
oil in turbocharger oil supply line fitting on turbocharger
before starting the engine.
WARNING: DO NOT rotate turbine wheel in turbocharger with your finger,
as sharp edges may exist.
3) Pour 3 ozs. (60 cc) of clean engine oil into turbocharger\
oil supply line fitting on turbocharger while using soft object to
rotate turbine wheel in turbocharger. This must be done to pre-
lubricate the turbocharger.
4) Install turbocharger oil supply line on turbocharger and
tighten nut to specification. See TORQUE SPECIFICATIONS. To install
remaining components, reverse removal procedure. Tighten bolts/nuts to
specification. See TORQUE SPECIFICATIONS.
