Dual Rear Wheels
Slots in the wheels will assist in properly orienting
the inner and outer wheels. Align these slots when
assembling the wheels for best access to the tire
valve on the inner wheel. The tires of both dual
wheels must be completely off the ground when
tightening to ensure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug
nut tightening adapter (included with the vehicle)
to correctly tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels,
use a proper vehicle lifting device.
NOTE:When installing a spare tire (if equipped) as part of
a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference, the
larger tire should be installed in a front location.
The correct direction of rotation for dual tire instal -
lations must also be observed.
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval Ú page 411.
Wheel Nuts
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels becoming elongated. This is especially important during the
first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to
recommended torque. Tighten the wheel nuts to
final torque in increments. Progress around the
bolt circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved Ú
page 411.

F EQUIPPED
Refer to Upfitters Body Builder’s Guide for
information on stowing your spare tire (if
equipped).
HUB CAPS/WHEEL COVERS —
I
F EQUIPPED
The hub caps must be removed before raising the
vehicle off the ground. For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull off
the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.

Lug Wrench Insertion Location — Hub Cap

On 3500 models with Dual Rear-Wheels (DRW),
you must first remove the hub caps—use the
procedure noted for the single rear wheel. For the
wheel covers (wheel skins), insert the flat end of
the lug wrench between the outer edge of the
wheel cover and the wheel. Pry against the wheel
to remove the wheel cover. Repeat this procedure
around the wheel until the cover pops off.
CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to the
center cap and/or the wheel if screwdriver type
tools are used. A pulling motion, not a pry off
motion, is recommended to remove the caps.

be compatible with the radiator engine coolant
and may plug the radiator.
This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not
recommended.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact an authorized dealer.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to
MS.90032) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be
used up to ten years or 150,000 miles
(240,000 km) before replacement. To prevent
reducing this extended maintenance period, it is
important to use the same engine coolant (OAT
coolant conforming to MS.90032) throughout the
life of your vehicle.
Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer Material Standard MS.90032
and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34°F (−37°C) are anticipated. Please contact
an authorized dealer for assistance.
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant solution. The use of lower quality water
will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact a local authorized
dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank
(if equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
WARNING!
Do not open a hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.

Blade Fuses
Power Distribution Center
The Power Distribution Center is located in the
engine compartment near the battery. This center
contains cartridge fuses, micro fuses, relays, and
circuit breakers. A description of each fuse and
component may be stamped on the inside cover,
otherwise the cavity number of each fuse is
stamped on the inside cover that corresponds to
the following chart.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Do not place a fuse inside a circuit
breaker cavity or vice versa. Failure to use
proper fuses may result in serious personal
injury, fire and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, transmission
system) or steering system blows, contact an
authorized dealer.
