accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
Extremely cold ambient temperature may require the
addition of a “winter front” for effective operation of the
cab heating/cooling system. Make certain that a percent-
age of the radiator is exposed for adequate air flow
through the charge air cooler and automatic transmission
oil cooler. The percentage of opening must be increased
with the increasing ambient air temperature and/or
engine load. If the cooling fan can be heard cycling
frequently, increase the size of the opening in the winter
front.Coolant bottle level check
The coolant reserve system provides a quick visual
method of determining that the coolant level is adequate.
With the engine idling, and warmed to the normal
operating temperature, the level of the coolant on the
coolant bottle should be between the fluid level marks.
Check the coolant level whenever the hood is raised.
The radiator normally remains completely full, so there is
no longer a need to remove the coolant pressure cap
except for checking coolant freeze point or replacement
with new antifreeze coolant.
WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool overheated engine! The coolant is under pres-
sure and severe scalding could result.

Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a“FULL” dot and an “ADD” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
full mark because leakage may occur at the cap.
With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type.
WARNING!
Use of a brake fluid that may have a lower initial
boiling point, or unidentified as to specification, may
result in sudden brake failure during hard prolonged
braking. You could have an accident.

Rear Axle And 4x4 Front Driving Axle Fluid Level
For Model 9.25 Front Axles and 10.5”/11.5” Rear Axles
refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type. For normal service, periodic fluid
level checks are not required. When the vehicle is ser-
viced for other reasons, the exterior surfaces of the axle
assembly should be inspected.
When checking the fluid level, the vehicle should be in a
level position. The fluid level should be 1/4” ± 1/4” (6.4
mm ± 6.4 mm) below the fill hole on the 9.25” Front Axle.
The fluid level should be 3/4” ± 1/4” (19 mm ± 6.4 mm)
below the fill hole on all 10.5” and 1/4” ± 1/4” (6.4 mm
± 6.4 mm) on 11.5” Rear Axles.
Drain And Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminatedwith water or subjected to severe service, follow the
recommended change intervals in Maintenance Schedule
“B” in Section 8 of this manual.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentialsin vehicles equipped with
10.5”/11.5” AxlesDO NOT REQUIREany limited slip
oil additive (friction modifiers).

Selection Of Lubricant
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type. It is important that the transmis-
sion fluid be maintained at the prescribed level using the
recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants and Genuine Parts for correct
fluid type.
Automatic Transmission Fluid and Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center. It is important that the
transmission be adjusted periodically, the fluid main-
tained at the correct level, and that it be drained and
refilled as specified.
It is important that proper lubricant is used in the
transmission. Refer to Fluids, Lubricants and Genuine
Parts for the correct lubricant type. A band adjustment
and filter change should be made at the time of the oil
change.
The fluid and filter(s) should be changed and the bands
adjusted (if equipped) as specified in the Maintenance
Schedule (Section 8). Vehicles with a 5.9L Diesel Engine,
having severe usage should follow Maintenance Sched-
ule “B” of the Maintenance Schedule (Section 8).

•Use Mopar touch up paint on scratches as soon as
possible. Your dealer has touch up paint to match the
color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil, use Mopar Wheel Cleaner or select a nonabra-
sive, non-acidic cleaner. Do not use scouring pads, steel
wool, a bristle brush or metal polishes. Only Mopar
cleaners are recommended. Do not use oven cleaner.
Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.

Interior Care
Use Mopar Total Clean to clean fabric upholstery and
carpeting.
Use Mopar Total Clean to clean vinyl upholstery.
Mopar Total Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and Mopar Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with Mopar Glass Cleaner or any commercial household-
type glass cleaner. Never use an abrasive type cleaner.
Use caution when cleaning the inside rear window
equipped with electric defrosters or the right rear quarter
window equipped with the radio antenna. Do not use
scrapers or other sharp instruments which may scratch
the elements. When cleaning the rear view mirror, spray
cleaner on the towel or rag that you are using. Do not
spray cleaner directly on the mirror.
