API CERTIFICATION AND LICENSE SYMBOL
Use an engine oil that is API Certified (GF-3) and
Licensed to display the certification mark (Fig. 2).
MOPARtprovides engine oils that meet or exceed,
Material Standard MS-6395 requirement.
SAE VISCOSITY
SAE 5W-20 and SAE 5W-30 engine oils are rec-
ommended for all operating temperatures.
These engine oils are designed to improve low
temperature starting and vehicle fuel economy.
Refer to the engine oil filler cap for the pre-
ferred engine oil viscosity grade for each vehi-
cle (Fig. 3).SAE viscosity grades are used to specify
the correct viscosity oil for an engine. Use only Multi-
Viscosity oils such as SAE 5W-20 or 5W-30. These
are specified with a dual SAE viscosity grade which
indicates the cold (5W) to hot (20, 30) temperature
performance range of the oil.
CONTAINER IDENTIFICATION
The Engine Oil Certificarion Mark was developed
and trademarked by the API to refer customers to
those engine oils preferred by the automobile manu-
facturers. This symbol means that the oil has been
certified and licensed by the American Petroleum
Institute (API). This certification mark will only be
found on the front of the oil containers. Those oilsthat do not display the ªMarkº on the front of the
container should not be used (Fig. 2).
DiamlerChrysler only recommends API Certified
engine oils that meet the requirements of Material
Standard MS-6395. Use Mopar or an equivalent oil
meeting the specification MS-6395.
SYNTHETIC ENGINE OILS
There are a number of engine oils being promoted
as either synthetic or semi-synthetic. If you chose to
use such a product, useonlythose oils that are cer-
tified by the American Petroleum Institute (API) to
display the ªCertification Markº and show SAE vis-
cosity grade recommended for each vehicle. Follow
the service schedule that describes your driving type.
ENGINE OIL ADDITIVES/SUPPLEMENTS
The manufacturerdoes not recommendthe addi-
tion of any engine oil additives/supplements to the
specified engine oil. Engine oil additives/supplements
should not be used to enhance engine oil perfor-
mance. Engine oil additives/supplements should not
be used to extend engine oil change intervals. No
additive is known to be safe for engine durability and
can degrade emission components. Additives can con-
tain undesirable materials that harm the long term
durability of engines by:
²Increasing the level of Phosphorus and Sulfur in
the engine oil. The API Certified Engine Oils control
the Phosphorus and Sulfur contents of the oil to lev-
els that reduce the contamination effect on the vehi-
cles emission control system.
²Altering the viscosity characteristics of the
engine oil so that it no longer meets the require-
ments of the specified viscosity grade.
²Creating potential for an undesirable additive
compatibility interaction in the engine crankcase.
The engine oils contain a performance additive sys-
tem carefully developed to optimize the oils perfor-
mance in the engine. The addition of supplements
may cause the oil to thicken prematurely, cause
excessive deposit build up and potentially shorten
engine life.
AXLE 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

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 WHEN
ENGINE 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 theradiator 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.

FLUID TYPES (Continued)

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/MANUAL
TRANSAXLE FLUID
NOTE: Refer to the maintenance schedules for the
recommended maintenance (fluid/filter change)
intervals for these transaxles.
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) is
required in the 4XTE automatic and T850 manual
transaxles. Substitute fluids can induce transmission
problems and/or failure.
MopartATF+4 (Automatic Transmission Fluid)
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.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued heavy
spark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers world-wide have
issued and endorsed consistent gasoline specifications
(the Worldwide Fuel Charter, WWFC) to define fuel

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 DIN EN 590 (Class0-4)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 as long as
it meets ASTM D 975: 1D and 2D and the quality of
lubrication behavior is in accordance with DIN EN
590. This will provide better protection from fuel gel-
ling 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 follow
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 performance.

OPERATION
OPERATION - COOLING SYSTEM
The engine cooling systems primary purpose is to
maintain engine temperature in a range that will
provide satisfactory engine performance and emission
levels under all expected driving conditions. It also
provides hot water (coolant) for heater performance
and cooling for automatic transmission oil. It does
this by transferring heat from engine metal to cool-
ant, moving this heated coolant to the radiator, and
then transferring this heat to the ambient air.
²When engine is cold: thermostat is closed, cool-
ing system has no flow through the radiator. The
coolant bypass flows through the engine only.
²When engine is warm: thermostat is open, cool-
ing system has bypass flow and coolant flow through
radiator.
Coolant flow circuits for the 2.4L and 3.3/3.8L
engines are shown in (Fig. 2).
OPERATION - HOSE CLAMPS
The spring type hose clamp applies constant ten-
sion on a hose connection. To remove a spring type
hose clamp, use Special Tool 6094 or equivalent, con-
stant tension clamp pliers (Fig. 3) to compress the
hose clamp.

COOLING (Continued)

With engine not running, remove radiator pressure
cap and wipe the radiator filler neck sealing seat
clean. The radiator should be full.
Attach the Cooling System Tester 7700 or equiva-
lent to the radiator, as shown in (Fig. 4) and apply
104 kPa (15 psi) pressure. If the pressure drops more
than 13.8 kPa (2 psi) in 2 minutes, inspect all points
for external leaks.
All radiator and heater hoses should be shaken
while at 104 kPa (15 psi), since some leaks occur only
while driving due to engine movement.If there are no external leaks, after the gauge dial
shows a drop in pressure, detach the tester. Start
engine and run until the thermostat opens, allowing
the coolant to expand. Reattach the cooling system
tester. If the needle on the dial fluctuates it indicates
a combustion leak, usually a head gasket leak.
WARNING: WITH TOOL IN PLACE, PRESSURE WILL
BUILD UP FAST. EXCESSIVE PRESSURE BUILT UP,
BY CONTINUOUS ENGINE OPERATION, MUST BE
RELEASED TO A SAFE PRESSURE POINT. NEVER
PERMIT PRESSURE TO EXCEED 138 kPa (20 psi).
If the needle on the dial does not fluctuate, raise
the engine rpm a few times. If an abnormal amount
of coolant or steam emits from the tailpipe, it may
indicate a coolant leak caused by a faulty head gas-
ket, cracked engine block, or cracked cylinder head.
There may be internal leaks that can be deter-
mined by removing the oil dipstick. If water globules
appear intermixed with the oil it will indicate an
internal leak in the engine. If there is an internal
leak, the engine must be disassembled for repair.
DIAGNOSIS AND TESTING - COOLING SYSTEM
FLOW CHECK
To determine whether coolant is flowing through
the cooling system, use one of the following proce-
dures:
PREFERRED METHOD
WARNING: DO NOT REMOVE THE COOLING SYS-
TEM PRESSURE CAP OR ANY HOSE WITH THE
SYSTEM HOT AND UNDER PRESSURE BECAUSE
SERIOUS BURNS FROM COOLANT CAN OCCUR.
²Remove pressure cap when engine is cold.
Remove small amount of coolant. Idle engine until
thermostat opens. You should observe coolant flow
while looking down the filler neck. Once flow is
detected install the pressure cap. Replace removed
