When service is required, DaimlerChrysler Corpo-
ration recommends that only Mopartbrand parts,
lubricants and chemicals be used. Mopartprovides
the best engineered products for servicing
DaimlerChrysler Corporation vehicles.
Only lubricants bearing designations defined by
the following organization should be used.
²Society of Automotive Engineers (SAE)
²American Petroleum Institute (API)
²National Lubricating Grease Institute (NLGI)
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Certified. MOPARt
provides engine oils, that meet or exceed this
requirement.
SAE VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. Use only engine oils with multi-
ple viscosities such as 5W-30 or 10W-30. These are
specified with a dual SAE viscosity grade which indi-
cates the cold-to-hot temperature viscosity range.
Select an engine oil that is best suited to your par-
ticular temperature range and variation (Fig. 2).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for
gasoline engines. The designation of ENERGY CON-
SERVING is located on the label of an engine oil con-
tainer.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have
been adopted to aid in the proper selection of engine
oil. The identifying notations are located on the front
label of engine oil plastic bottles and the top of
engine oil cans (Fig. 3).
This symbol means that the oil has been certified
by the American Petroleum Institute (API). Diamler-
Chrysler only recommend API Certified engine oils.
Use Mopartengine oil or equivalent.

GEAR LUBRICANTS
SAE ratings also apply to multigrade gear lubri-
cants. In addition, API classification defines the
lubricants usage. Such as API GL-5 and SAE 75W-
90.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 4) on the label. At the bottom of the
NLGI symbol is the usage and quality identification
letters. Wheel bearing lubricant is identified by the
letter ªGº. Chassis lubricant is identified by the letter
ªLº. The letter following the usage letter indicates
the quality of the lubricant. The following symbols
indicate the highest quality.
SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may
require the use of specialized lubricants or oils. Con-
sult the appropriate sections in this manual for the
correct application of these lubricants.
DESCRIPTION - ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHENENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants
is not recommended, as they provide less freeze
protection and less boiling protection.
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 and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder
heads, and water pumps requires special corrosion
protection. MopartAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769), or the equiva-
lent ethylene glycol base coolant with hybrid organic
corrosion inhibitors (called HOAT, for Hybrid Organic
Additive Technology) is recommended. This coolant
offers the best engine cooling without corrosion when
mixed with 50% Ethylene Glycol and 50% distilled
water to obtain a freeze point of -37ÉC (-35ÉF). If it
loses color or becomes contaminated, drain, flush,
and replace with fresh properly mixed coolant solu-
tion.
The green coolantMUST NOT BE MIXEDwith
the orange or magenta coolants. When replacing cool-
ant the complete system flush must be performed
before using the replacement coolant.
CAUTION: MoparTAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769) may not be
mixed with any other type of antifreeze. Doing so
will reduce the corrosion protection and may result
in premature water pump seal failure. If non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.DESCRIPTION - FLEXIBLE FUEL ENGINE OIL
The information in this section is for Flexible Fuel
Vehicles (FFV) only. These vehicles can be identified
by the unique Fuel Filler Door Label that states
Ethanol (E-85) or Unleaded Gasoline Only. This sec-
tion only covers those subjects that are unique to
these vehicles. Please refer to the other sections of
this manual for information on features that are
common between Flexible Fuel and gasoline only
powered vehicles.
ETHANOL FUEL (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.

WARNING: Ethanol vapors are extremely flammable
and could cause serious personal injury. Never
have any smoking materials lit in or near the vehi-
cle when removing the fuel filler tube cap (gas cap)
or filling the tank. Do not use E-85 as a cleaning
agent and never use it near an open flame.
FUEL REQUIREMENTS
The vehicle will operate on both unleaded gasoline
with an octane rating of 87, or E-85 fuel, or any mix-
ture of these two.
For best results, a refueling pattern that alternates
between E-85 and unleaded gasoline should be
avoided. When you do switch fuels, it is recom-
mended that
²you do not switch when the fuel gauge indicates
less than 1/4 full
²you do not add less than 5 gallons when refuel-
ing
²you operate the vehicle immediately after refuel-
ing for a period of at least 5 minutes
Observing these precautions will avoid possible
hard starting and/or significant deterioration in
driveability during warm up.
FFV STARTING
The characteristics of E-85 fuel make it unsuitable
for use when ambient temperatures fall below 0ÉF. In
the range of 0ÉF to 32ÉF, you may experience an
increase in the time it takes for your engine to start,
and a deterioration in driveability (sags and/or hesi-
tations) until the engine is fully warmed up.
Engine Operating on E-85 Fuel
If vehicle operates on E-85 fuel either full or part-
time, use only MopartFlexible Fuel 5W-30 engine oil
or an equivalent that meets DaimlerChrysler Stan-
dard MS-9214. Equivalent commercial Flexible Fuel
engine oils may be labeled as Multi-Fuel, Variable
Fuel, Flexible Fuel, etc. These engine oils may be
satisfactory if they meet the DaimlerChrysler Stan-
dard.
SAE 5W-30 engine oil is preferred for use in Flex-
ible Fuel engines.
CAUTION: If Flexible Fuel engine oil is not used
when using E-85 fuel, engine wear or damage may
result.
CRUISING RANGE
Because E-85 fuel contains less energy per gallon
than gasoline, you will experience an increase in fuel
consumption. You can expect your MPG and your
driving range to decrease by about 30% compared to
gasoline operation.
DESCRIPTION - AUTOMATIC TRANSMISSION
FLUID
NOTE: Refer to the maintenance schedules for the
recommended maintenance (fluid/filter change)
intervals for this transaxle.
NOTE: All transaxles have a common transmission
and differential sump. Filling the transaxle accom-
modates the differential as well.
TRANSMISSION FLUID
MopartATF+4 (Automatic Transmission Fluid-
Type 9602) is required in the 41TE automatic and
T850 manual transaxles. Substitute fluids can induce
torque converter clutch shudder.
MopartATF+4 (Automatic Transmission Fluid-
Type 9602) when new is red in color. The ATF is dyed
red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red
color is not permanent and is not an indicator of fluid
condition. As the vehicle is driven, the ATF will begin
to look darker in color and may eventually become
brown.This is normal.ATF+4 also has a unique
odor that may change with age. Consequently,odor
and color cannot be used to indicate the fluid
condition or the need for a fluid change.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.
DESCRIPTION - FUEL REQUIREMENTS
Your engine is designed to meet all emissions reg-
ulations and provide excellent fuel economy and per-
formance when using high quality unleaded gasoline
having an octane rating of 87. The use of premium
gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality reg-
ular gasoline, and in some circumstances may result
in poorer performance.

²The use of fuel additives which are now being
sold as octane enhancers is not recommended. Most
of these products contain high concentrations of
methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such fuels
or additives is not the responsibility of
DaimlerChrysler Corporation and may not be covered
under the new vehicle warranty.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
DESCRIPTION - FUEL REQUIREMENTS -
DIESEL ENGINE
WARNING: DO NOT USE ALCOHOL OR GASOLINE
AS A FUEL BLENDING AGENT. THEY CAN BE
UNSTABLE UNDER CERTAIN CONDITIONS AND
HAZARDOUS OR EXPLOSIVE WHEN MIXED WITH
DIESEL FUEL.
Use good quality diesel fuel from a reputable sup-
plier. For most year-round service, number 2 diesel
fuel meeting ASTM specification D-975 will provide
good performance. If the vehicle is exposed to
extreme cold (below -18ÉC/0ÉF) or is required to oper-
ate at colder than normal conditions for prolonged
periods, use climatize No. 2 diesel fuel or dilute the
No. 2 diesel fuel with 50% No. 1 diesel fuel. This will
provide better protection from fuel gelling or wax
plugging of the fuel filters.
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, including fuel line freez-
ing in winter, drain the accumulated water from the
fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and fol-
low the cold weather advice above, fuel conditioners
should not be required in your vehicle. If available in
your area, a high cetane ªpremiumº diesel fuel may
offer improved cold starting and warm up perfor-
mance.
DESCRIPTION - ENGINE OIL - DIESEL
ENGINES
Use only Diesel Engine Oil meeting standardMIL-
2104Cor API ClassificationCD or higherorCCML
D4, D5.
SAE VISCOSITY GRADE
CAUTION: Low viscosity oils must have the proper
API quality or the CCMC G5 designation.
To assure of properly formulated engine oils, it is
recommended that SAE Grade 10W-40 engine oilsthat meet Chrysler material standard MS-6395, be
used. European Grade 10W-40 oils are also accept-
able.
Oils of the SAE 5W-40 or 8W-80 grade number are
preferred when minimum temperatures consistently

STRUT
DESCRIPTION - STRUT ASSEMBLY
A Macpherson type strut assembly is used in place
of a conventional front suspension's upper control
arm and upper ball joint. The bottom of the strut
mounts directly to the steering knuckle using two
bolts and nuts going through the strut clevis bracket
and steering knuckle. The top of the strut mounts
directly to the strut tower of the vehicle using the
threaded studs on the strut assemblies upper mount.
The strut assembly includes the components listed
in the figure (Fig. 38).
Each component is serviced by removing the strut
assembly from the vehicle and disassembling it.
The coil springs are side-oriented. Springs on the
left side of the vehicle have a left-hand wind top-to-
bottom while springs on the right side have a right-
hand wind top-to-bottom. This helps provide better
vehicle stability during jounce and rebound maneu-
vers of the front suspension. Left and right springs
must not be interchanged. Coil springs are rated sep-
arately for each corner or side of the vehicle depend-
ing on optional equipment and type of vehicle
service. If the coil springs require replacement, be
sure that the springs are replaced with springs meet-
ing the correct load rating and spring rate for the
vehicle and its specific options.
OPERATION - STRUT ASSEMBLY
The strut assembly cushions the ride of the vehicle,
controlling vibration, along with jounce and rebound
of the suspension.

The coil spring controls ride quality and maintains
proper ride height.
The spring isolators isolate the coil spring at the
top and bottom from coming into metal-to-metal con-
tact with the upper seat and strut.
The jounce bumper limits suspension travel and
metal-to-metal contact under full jounce condition.
The strut dampens jounce and rebound motions of
the coil spring and suspension.
During steering maneuvers, the strut assembly
(through a pivot bearing in the upper strut mount)
and steering knuckle (through the lower ball joint)
turn as an assembly.
DIAGNOSIS AND TESTING - STRUT ASSEMBLY
(1) Inspect for damaged or broken coil springs
(Fig. 38).
(2) Inspect for torn or damaged strut assembly
dust boots (Fig. 38).
(3) Inspect the coil spring isolator on the lower
spring seat for any signs of damage or deterioration.
(4) Lift dust boot (Fig. 39) and inspect strut
assembly for evidence of fluid running from the
upper end of fluid reservoir. (Actual leakage will be astream of fluid running down the side and dripping
off lower end of unit). A slight amount of seepage
between the strut rod and strut shaft seal is not
unusual and does not affect performance of the strut
assembly (Fig. 39). Also inspect jounce bumpers for
signs of damage or deterioration.
REMOVAL - STRUT ASSEMBLY
WARNING: DO NOT REMOVE THE NUT FROM THE
STRUT ROD WHILE STRUT ASSEMBLY IS
INSTALLED IN VEHICLE, OR BEFORE STRUT
ASSEMBLY SPRING IS COMPRESSED.
(1) Raise the vehicle. See Hoisting in Lubrication
and Maintenance.
(2) Remove the wheel and tire assembly from loca-
tion on front of vehicle requiring strut removal.
(3) If both strut assemblies are to be removed,
mark the strut assemblies right or left according to
which side of the vehicle they were removed from.
(4) Remove the hydraulic brake hose routing
bracket and the speed sensor cable routing bracket
from the strut damper brackets (Fig. 40).

remove the strut assembly from the vehicle.
(8) To disassemble the strut assembly, (Refer to 2 -
SUSPENSION/FRONT/STRUT - DISASSEMBLY).
DISASSEMBLY - STRUT ASSEMBLY
The strut assembly must be removed from the
vehicle for it to be disassembled and assembled.
For the disassembly and assembly of the strut
assembly, use of Strut Spring Compressor, Pentastar
Service Equipment (PSE) tool W-7200, or the equiva-
lent, is recommended to compress the coil spring.
Follow the manufacturer's instructions closely.
WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT BEFORE THE COIL SPRING IS COMPRESSED.
THE COIL SPRING IS HELD UNDER PRESSURE
AND MUST BE COMPRESSED, REMOVING SPRING
TENSION FROM THE UPPER MOUNT AND PIVOT
BEARING, BEFORE THE SHAFT NUT IS REMOVED.
(1) Position the strut assembly in the strut coil
spring compressor following the manufacturers
instructions. Position the lower hooks on the coil
spring first. The strut clevis bracket should be posi-
tioned straight outward from the compressor.
(2) Turn the upper mount of the strut assembly
toward the inside of the compressor as shown to
allow positioning of the compressor upper hooks (Fig.
44). Position the upper hooks on top of the coil spring
upper seat approximately 1 inch from outside diame-
ter of seat (Fig. 47).Do not allow hooks to be
placed closer to edge.Place a clamp on the lowerend of the coil spring, so the strut is held in place
once the strut shaft nut is removed.
(3) Compress the coil spring until all coil spring
tension is removed from the upper mount.
(4) Install Strut Nut Socket, Special Tool 6864, on
the strut shaft retaining nut (Fig. 45). Next, install a
10 mm socket on the hex on the end of the strut
shaft. While holding the strut shaft from turning,
remove the nut from the strut shaft.
(5) Remove the upper mount from the strut shaft.
(6) If the pivot bearing needs to be serviced,
remove it from the top of the coil spring upper seat
by pulling it straight up.
(7) Remove the clamp from the bottom of the coil
spring and remove the strut out through the bottom
of the coil spring.
NOTE: If the coil spring or upper spring seat needs
to be serviced, proceed with the next step, other-
wise, proceed with step 10.
(8) Release the tension from the coil spring by
backing off the compressor drive fully. Push back the
compressor upper hooks and remove the upper spring
seat with upper spring isolator.
(9) Remove the coil spring from the spring com-
pressor.
