INTRODUCTION
Jeeptlubrication and maintenance is divided into
required and recommended service tasks.
The recommendations and procedures listed in this
group are intended for JeeptDealer Service Personnel.
Because conditions vary, it is necessary to schedule
service tasks according to a time interval as well as a
distance interval.
It is the owner's responsibility to have vehicle ser-
viced. Owner is to pay for labor and necessary parts
that are not covered by the warranty.
Additional lubrication and maintenance informa-
tion is listed in the Owner's Manual, which is in-
cluded with the vehicle.
SEVERE DRIVING CONDITIONS
When a vehicle is subjected to a severe driving con-
dition, time between recommended maintenance
should be decreased.
Refer to Engine Maintenance for the engine oil and
filter maintenance interval when involved with a se-
vere driving condition.
A severe driving condition is defined as either:
²frequent short trip driving less than 24 km (15
miles);
²frequent driving in a dusty environment;
²trailer towing;
²extensive engine idling;
²sustained high-speed operation;
²desert operation;
²frequent starting and stopping;²cold-climate operation;
²off-road driving; or
²commercial service.
To service a Jeeptvehicle for a severe driving con-
dition, change all the lubricating fluids and lubricate:
²the body components,
²all the driveline coupling joints, and
²the steering linkage
more often than for a normal driving condition to
prevent excessive wear of the components.
DUSTY AREAS
Driving in an area with dust-filled air increases the
risk of particles entering the engine and crankcase.
With this type of severe driving condition, attention
should be given to the engine and crankcase compo-
nents.
OFF-ROAD (4WD) OPERATION
After completion of off-road (4WD) operation, the
underside of the vehicle should be thoroughly in-
spected. Examine threaded fasteners for looseness.
HARSH SURFACE ENVIRONMENTS
After vehicle operation in a harsh surface environ-
ment, the following components should be inspected
and cleaned as soon as possible:
²brake drums,
²brake linings,
²front wheel bearings (2WD vehicles only), and
²axle coupling joints.
This will prevent wear and/or unpredictable brake
action.

PORTABLE STARTING UNIT
There are many types of portable starting units
available for starting engines. Follow the manufac-
turer's instructions when involved in any engine
starting procedure.
HOISTING RECOMMENDATIONS
FLOOR JACK
When properly positioned, a floor jack can be used
to lift a Jeeptvehicle. Support the vehicle in the
raised position with jack stands at the front and rear
ends as applicable (Fig. 7).
CAUTION: Do not attempt to lift a JeepTvehicle
with a floor jack positioned under:
²an axle tube,
²a body side sill,
²a steering linkage component,
²a drive shaft,
²the engine or transmission oil pan,
²the fuel tank, or
²a front suspension arm.
Use the correct sub-frame rail or frame rail
lifting locations only (Fig. 7).
HOIST
A Jeeptvehicle can be lifted with a swiveling-arm
type hoist; with a wheel-lift, twin-post hoist; or with
a ramp-type, drive-on hoist.
When a swiveling-arm, frame-contact type
hoist is used, ensure that the lifting pads are po-
sitioned at the correct sub frame rail (Fig. 7).
TOWING RECOMMENDATIONS
TOWING EQUIPMENT
A vehicle equipped with SAE approved sling-type
towing equipment can be used to tow all Jeeptvehi-
cles (Fig. 8). When it is necessary to rear-tow a vehi-
cle, use the wheel-lift towing method with a tow
dolly located under the front wheels. A vehicle with
flat-bed towing equipment can also be used to trans-
port a disabled vehicle.
A wooden crossbeam with spacer blocks could pos-
sibly be required for proper connection when using
the sling-type, front-end towing method (Fig. 9).
SAFETY PRECAUTIONS
The following safety precautions must be consid-
ered when preparing for and during a vehicle towing
operation:

0 - 8 LUBRICATION AND MAINTENANCEJ

²if the vehicle is damaged, secure the loose and pro-
truding parts;
²always use a safety chain system that is indepen-
dent of the lifting and towing equipment;
²do not allow any of the towing equipment to con-
tact the disabled vehicle's fuel tank;
²do not allow anyone to be under the disabled vehi-
cle while it is lifted by the towing equipment;
²do not allow passengers to ride in a vehicle being
towed;
²always observe all state and local laws involving
warning signals, night illumination, speed, etc.
²do not attempt a towing operation that could jeop-
ardize the safety of the operator, bystanders or other
motorists;
²do not exceed a towing speed of 48 km/h (30 mph);
²avoid towing distances of more than 24 km (15
miles) whenever possible; and
²do not attach tow chains or a tow sling to a
bumper, the steering linkage, the universal joints,
the constant velocity (CV) joints, or a drive shaft.
CLEARANCES AND RAMP ANGLE
SURFACE CLEARANCE
The end of the disabled vehicle that is attached to
the tow vehicle should be lifted a minimum of 10 cm
or four inches off the surface. Inspect to ensure that
the opposite end of the disabled vehicle has clearance
from the surface.
RAMP ANGLEÐFLAT-BED TOWING
If a vehicle with flat-bed towing equipment is used,
the approach ramp angle should not exceed 15 de-
grees.
SLING-TYPE, FRONT-END TOWING
XJ VEHICLES
Use the following guidelines when the tow vehicle
is attached to the front end of a disabled vehicle.
(1) Always tow with the front wheels lifted off the
surface and turned all the way to the right.
(2) Attach a J-hook to the disabled vehicle at the
left side of the axle (Fig. 10).
(3) Position the sling crossbar close to the J-hook
and below the front bumper (Fig. 11).
(4) Secure a chain to the right side of vehicle by
placing it over the axle shaft tube and attaching it to
a structural member.
(5) Attach the safety chains to the vehicle.
2WD With Manual Or Automatic Transmission
(6) Turn the ignition switch to the OFF position to
unlock the steering wheel.
(7) Shift the transmission to NEUTRAL, mark the
drive shaft and axle drive pinion gear shaft yoke for
installation reference. Remove the drive shaft from
the vehicle.(8) Cover the exposed end of the transmission ex-
tension housing and the universal joints. Store the
drive shaft in a safe place.
4WD, Command-Trac (231 Part-Time 4WD
Transfer Case) And Manual Transmission
(6) Turn the ignition switch to the OFF position to
unlock the steering wheel.
When the transfer case is in the NEUTRAL po-
sition, both axles are disengaged from the pow-
ertrain. This allows the vehicle to be towed
without removing the drive shafts.
(7) Shift the manual transmission into a forward
gear and the transfer case to NEUTRAL.
4WD, Command-Trac (231 Part-Time 4WD
Transfer Case) And Automatic Transmission
(6) Turn the ignition switch to the OFF position to
unlock the steering wheel.

ENGINE BREAK-IN
After first starting a new engine, allow it to idle
and warm up for at least 15 seconds before shifting
the transmission into a drive gear.
Drive the vehicle at:
²varying speeds less than 80 km/h (50 mph) for the
first 160 km (100 miles), and
²speeds less than 88 km/h (55 mph) for the first 800
km (500 miles).
Avoid driving at full-throttle for extended periods
of time. Also, avoid fast acceleration and sudden
stops.
A special break-in engine oil is not required. The
original oil installed in a vehicle is a quality lubri-
cant. There is no requirement to have the oil
changed or the oil filter replaced until the first
scheduled maintenance interval.
The engine oil, coolant and all the other engine re-
lated fluid levels should be determined on a regular
basis.
ENGINE OIL
SPECIFICATIONS
API SERVICE GRADE
For maximum engine protection during all driving
conditions, install an engine oil that conforms to API
Service Grade. MOPAR Engine Oil conforms to all of
these API Service Grades.
SAE VISCOSITY
SAE designated multi-viscosity grade engine oil is
to protect engines. This type of engine oil can usually
be installed and remain in the engine until the next
scheduled oil change. Select the engine oil viscosity
according to the lowest ambient air temperature ex-
pected before the next scheduled oil change (Fig.1).
Low viscosity engine oil allows easier engine starting
during cold weather. SAE 5W-30 viscosity engine oil
is recommended when the ambient air temperatures
consistently decrease to below 10ÉF (-12ÉC).ENERGY CONSERVING OIL
In selecting the correct API grade and SAE grade,
anENERGY CONSERVINGtype engine oil is also
recommended.
CONTAINER IDENTIFICATION
Standard engine oil notations have been adopted
for selection of engine oil. The notations are located
on side of plastic bottles and on the top of engine oil
cans (Fig. 2).
²The top, outer field contains theAPI Service
Gradenotation for the engine oil.

CAUTION: Do not tap the filter element or immerse
the filter in liquid to remove trapped particles.
(3) Clean filter element by gently blowing the
trapped particles from the filter with compressed air.
Direct air in the opposite direction of normal intake
air flow. Keep air nozzle at least two inches away
from the filter to avoid damage to filter.
(4) If the filter has become partially saturated with
oil, replace the filter. Test the crankcase ventilating
(CCV) system for proper operation.
(5) Wash the air cleaner cover and body/housing
(Figs. 10) with cleaning solvent and wipe dry.
(6) Install the air cleaner filter element and attach
the cover to the body/housing.
CRANKCASE VENTILATION SYSTEM
All Jeept2.5L and 4.0L engines are equipped with
a crankcase ventilation (CCV) system. Refer to
Group 25ÐEmissions, for additional information.
FUEL USAGE STATEMENTÐGAS ENGINES
Jeeptvehicles are designed to meet all emission
regulations and provide excellent fuel economy using
high quality unleaded gasoline. Only use unleaded
gasolines having a minimum posted octane of 87.
If a Jeeptvehicle develops occasional light spark
knock (ping) at low engine speeds, this is not harm-
ful. However,continued heavy knock at high
speeds can cause damage and should be
checked immediately.Engine damage as a result of
heavy knock operation may not be covered by the
new vehicle warranty.In addition to using unleaded gasoline with the
proper octane rating,those that contain deter-
gents, corrosion and stability additives are rec-
ommended.Using gasolines that have these
additives will help improve fuel economy, reduce
emissions and maintain vehicle performance. Gener-
ally, premium unleaded gasolines contain more addi-
tive than regular unleaded gasolines.
Poor quality gasolinecan cause problems such as
hard starting, stalling and stumble. If these problems
occur, use another brand of gasoline before consider-
ing servicing the vehicle.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
materials that contain oxygen such as alcohol, MTBE
and ETBE. The type and amount of oxygenate used
in the blend is important. The following are gener-
ally used in gasoline blends:
ETHANOL
Ethanol (Ethyl or Grain Alcohol) properly blended,
is used as a mixture of 10 percent ethanol and 90
percent gasoline.Gasoline with ethanol may be
used in your vehicle.
METHANOL
CAUTION: Do not use gasolines containing metha-
nol. Use of methanol/gasoline blends may result in
starting and driveability problems. In addition, dam-
age may be done to critical fuel system compo-
nents.
Methanol (Methyl or Wood Alcohol) is used in a va-
riety of concentrations blended with unleaded gaso-
line. You may encounter fuels containing 3 percent
or more methanol along with other alcohols called co-
solvents.
Problems that are the result of using methanol/gas-
oline blends are not the responsibility of Chrysler
Corporation. They may not be covered by the vehicle
warranty.
MTBE/ETBE
Gasoline and MTBE (Methyl Tertiary Butyl Ether)
blends are a mixture of unleaded gasoline and up to
15 percent MTBE. Gasoline and ETBE (Ethyl Ter-
tiary Butyl Ether) are blends of gasoline and up to
17 percent ETBE. Gasoline blended with MTBE or
ETBE may be used.
CLEAN AIR GASOLINE
Many gasolines are now being blended that con-
tribute to cleaner air, especially in those areas of the
country where air pollution levels are high. These
new blends provide a cleaner burning fuel and some
are referred to asReformulated Gasoline.

FUEL PUMP MODULE
The fuel pump module is installed in the top of the
fuel tank. The fuel pump module contains the follow-
ing components:
²Electric fuel pump
²Fuel pump reservoir
²In-tank fuel filter
²Fuel gauge sending unit
²Fuel supply and return tube connections
The fuel pump used on all vehicles is a gear/rotor
type pump. It is driven by a permanent magnet 12
volt electric motor that is immersed in the fuel tank.
The electrical pump is integral with the fuel sender
unit. The pump/sender assembly is installed inside
the fuel tank.
The fuel pump has a check valve at the outlet end
that consists of a ball held against a seat by force ap-
plied from a spring. When the pump is operating,
fuel pressure overcomes spring pressure and forces
the ball off its seat, allowing fuel to flow. When the
pump is not operating, spring pressure forces the ball
back against the seat preventing fuel backflow
through the pump.
Fuel system pressure is maintained at approxi-
mately 214 kPa (31 psi). This is when the pump is
operating and vacuum is supplied to the fuel pres-
sure regulator. If vacuum is not supplied to the pres-
sure regulator, fuel pressure will be approximately
55-69 kPa (8-10 psi) higher. This may be due to a
broken or clogged vacuum line. When the fuel pumpis not operating, system fuel pressure of 131-269 kPa
(19-39 psi) is maintained. This is done by the fuel
pump outlet check valve and the vacuum assisted
fuel pressure regulator.
REMOVALÐXJ MODELS
The fuel pump/gauge sender unit assembly can be
removed from the fuel tank without removing the
tank from the vehicle.
WARNING: THE FUEL SYSTEM IS UNDER A CON-
STANT PRESSURE (EVEN WITH THE ENGINE OFF).
BEFORE SERVICING THE FUEL PUMP MODULE,
THE FUEL SYSTEM PRESSURE MUST BE RE-
LEASED. REFER TO THE FUEL PRESSURE RE-
LEASE PROCEDURE IN THIS GROUP.
WARNING: EXTINGUISH ALL TOBACCO SMOKING
PRODUCTS BEFORE SERVICING THE FUEL SYS-
TEM. KEEP OPEN FLAME AWAY FROM FUEL SYS-
TEM COMPONENTS.
(1) Remove fuel filler cap. Perform the Fuel Pres-
sure Release Procedure as outlined in this group.
(2) Disconnect negative battery cable.
(3) Using an approved portable gasoline siphon/

nect Fittings.
WARNING: THE FUEL SYSTEM IS UNDER A CON-
STANT PRESSURE (EVEN WITH THE ENGINE OFF).
BEFORE SERVICING ANY FUEL SYSTEM HOSES,
FITTINGS OR LINES, THE FUEL SYSTEM PRES-
SURE MUST BE RELEASED. REFER TO THE FUEL
PRESSURE RELEASE PROCEDURE IN THIS
GROUP.
Inspect all hose connections such as clamps, cou-
plings and fittings to make sure they are secure and
leaks are not present. The component should be re-
placed immediately if there is any evidence of degra-
dation that could result in failure.
Never attempt to repair a plastic fuel line/tube. Re-
place as necessary.
Avoid contact of any fuel tubes/hoses with other ve-
hicle components that could cause abrasions or scuff-
ing. Be sure that the plastic fuel lines/tubes are
properly routed to prevent pinching and to avoid heat
sources.
The lines/tubes/hoses used on fuel injected vehicles
are of a special construction. This is due to the
higher fuel pressures and the possibility of contami-
nated fuel in this system. If it is necessary to replace
these lines/tubes/hoses, only those marked EFM/EFI
may be used.
The hose clamps used to secure rubber hoses on
fuel injected vehicles are of a special rolled edge con-
struction. This construction is used to prevent the
edge of the clamp from cutting into the hose. Only
these rolled edge type clamps may be used in this
system. All other types of clamps may cut into the
hoses and cause high pressure fuel leaks.
Use new original equipment type hose clamps.
Tighten hose clamps to 1 Nzm (15 in. lbs.) torque.
QUICK-CONNECT FITTINGS
Also refer to the previous Fuel Tubes/Lines/Hoses
and Clamps section.Different types of quick-connect fittings are used to
attach various fuel system components. These are: a
single-tab type, a two-tab type or a plastic retainer
ring type.
SINGLE-TAB TYPE
This type of fitting is equipped with a single pull
tab (Fig. 15). The tab is removable. After the tab is
removed, the quick-connect fitting can be separated
