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 label
of engine oil plastic bottles and the top of engine oil
cans (Fig. 4).
DESCRIPTIONÐENGINE OIL
API SERVICE GRADE CERTIFIED
WARNING: NEW OR USED ENGINE OIL CAN BE
IRRITATING TO THE SKIN. AVOID PROLONGED OR
REPEATED SKIN CONTACT WITH ENGINE OIL.
CONTAMINANTS IN USED ENGINE OIL, CAUSED BY
INTERNAL COMBUSTION, CAN BE HAZARDOUS TO
YOUR HEALTH. THOROUGHLY WASH EXPOSED
SKIN WITH SOAP AND WATER. DO NOT WASH
SKIN WITH GASOLINE, DIESEL FUEL, THINNER, OR
SOLVENTS, HEALTH PROBLEMS CAN RESULT. DO
NOT POLLUTE, DISPOSE OF USED ENGINE OIL

MENT AGENCY FOR LOCATION OF COLLECTION
CENTER IN YOUR AREA.Standard engine-oil identification notations have
been adopted to aid in the proper selection of engine
oil. The identifying notations are located on the label
of engine oil plastic bottles and the top of engine oil
cans.
In diesel engines, use an engine oil that conforms
to API Service Grade CF-4 or CG-4/SH (Fig. 5).
MOPARtprovides an engine oil that conforms to this
particular grade.
SAE VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. SAE 15W±40 specifies a multiple
viscosity engine oil.
When choosing an engine oil, consider the range of
temperatures the vehicle will be operated in before
the next oil change. Select an engine oil that is best
suited to your area's particular ambient temperature
range and variation. For diesel engines, refer to (Fig.
6).

DESCRIPTION
A multi-purpose, hypoid gear lubricant which con-
forms to the following specifications should be used.
Mopar Hypoid Gear Lubricant conforms to all of
these specifications.
SAE ratings also apply to multiple grade gear
lubricants. In addition, API classification defines the
lubricants usage.
FRONT AXLE
²The lubricant should have MIL-L-2105C and
API GL 5 quality specifications.
²Lubricant is SAE 75W-140 SYNTHETIC gear
lubricant.
REAR AXLE
²The lubricant should have MIL-L-2105C and
API GL 5 quality specifications.
²Lubricant is a thermally stable SAE 80W-90
gear lubricant.
²Lubricant for axles intended for heavy-duty or
trailer tow use is SAE 75W-140 SYNTHETIC gear
lubricant.
NOTE: Trac-lokYand Vari-lokYequipped axles
require a friction modifier be added to the lubricant.
CAUTION: If axle is submerged in water, lubricant
must be replaced immediately to avoid possible
premature axle failure.
DESCRIPTION - TRANSFER CASE FLUID
Recommended lubricant for the NV231 and NV241
transfer case is MopartATF +4, (MS 9602) Auto-
matic Transmission Fluid.
DESCRIPTION - AUTOMATIC TRANSMISSION
FLUID
NOTE: Refer to the maintenance schedules in this
group for the recommended maintenance (fluid/filter
change) intervals for this transmission.
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
MopartATF +4, type 9602, Automatic Transmis-
sion Fluid is the recommended fluid for Daimler-
Chrysler automatic transmissions.
Dexron II fluid IS NOT recommended. Clutch
chatter can result from the use of improper
fluid.MopartATF +4, type 9602, Automatic Transmis-
sion 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.A dark brown/black fluid
accompanied with a burnt odor and/or deterioration
in shift quality may indicate fluid deterioration or
transmission component failure.
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.
OPERATION - AUTOMATIC TRANSMISSION
FLUID
The automatic transmission fluid is selected based
upon several qualities. The fluid must provide a high
level of protection for the internal components by
providing a lubricating film between adjacent metal
components. The fluid must also be thermally stable
so that it can maintain a consistent viscosity through
a large temperature range. If the viscosity stays con-
stant through the temperature range of operation,
transmission operation and shift feel will remain con-
sistent. Transmission fluid must also be a good con-
ductor of heat. The fluid must absorb heat from the
internal transmission components and transfer that
heat to the transmission case.

MAINTENANCE SCHEDULES
LIGHT DUTY ENGINE (1500 AND 2500
MODELS EXCEPT 8.0L) MAINTENANCE
SCHEDULES
There are two maintenance schedules that show
proper service for the vehicle.
First is ScheduleªAº. It lists all the scheduled
maintenance to be performed under ªnormalº operat-
ing conditions.
Second is ScheduleªBºIt is a schedule for vehicles
that are operated under the conditions listed at the
beginning of that schedule.
Use the schedule that best describes the driving
conditions.
Where time and mileage are listed, follow the
interval that occurs first.
At Each Stop For Fuel
²Check engine oil level and add as required.
²Check windshield washer solvent and add as
required.
²Clean windshield and wiper blades as required.
Once A Month
²Check tire pressure and look for unusual wear
or damage.
²Inspect battery and clean and tighten terminals
as required.
²Check fluid levels of coolant reservoir, brake
master cylinder, power steering, and transmission
and add as needed.
²Check all lights and all other electrical items for
correct operation.
²Inspect and clean wiper blades. Replace if
required.
At Each Oil Change
²Inspect exhaust system.
²Inspect brake hoses.
²Adjust rear brake shoe to drum clearance.
²Rotate the tires at each oil change interval
shown on schedule ªAº (7,500 Miles) or every other
interval shown on schedule ªBº (6,000 Miles).
²Check engine coolant level, hoses, and clamps.
²Lubricate steering linkage.
EMISSION CONTROL SYSTEM MAINTENANCE
The scheduled emission maintenance listed inbold
typeon the Maintenance Schedules, must be done at
the mileage specified to assure the continued proper
functioning of the emission control system. These,
and all other maintenance services included in this
manual, should be done to provide the best vehicle
performance and reliability. More frequent mainte-
nance may be needed for vehicles in severe operatingconditions such as dusty areas and very short trip
driving.
