2005 DODGE POWER WAGON cooling

Wheels
Stylish forged aluminum 17wheels give the Power
Wagon a powerful stance. Forging a wheel from alumi-
num produces a stronger, lighter weight wheel than
machining or casting the wheel out of the same material.
Standard package features:
•
Fuel Tank Skid Plate - protects the fuel tank from
impingement damage.
•Transfer Case Skid Plate and Tubing - protects the
transfer case and exhaust catalyst from impingement
damage.
•Heavy Duty Cross Members - protects the under
carriage and supports the under body protection skid
plates.
•Fore/Aft rails - which connect the cross member for
additional support and prevent the truck from getting
hung up on large rocks between the cross members.
•Steering Dampener Skid Plate - protects the steering
dampener from impingement damage.
•Electronically Locking Front And Rear Axle Differen-
tials With 4:56 Gears - improves mobility and articu-
lation by locking the differentials.
•Electronically Disconnecting Stabilizer/Sway Bar - im-
proves mobility and articulation by disconnecting the
Stabilizer/Sway Bar.
•160 Amp Alternator - supplies increased electrical
power for the winch and other off-road accessories.
•Heavy Duty Battery - supplies increased electrical
power for the winch and other off-road accessories.

12. Electronic Throttle Control (ETC) Light 5.7L
Engines Only
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.13. Temperature Gauge
The temperature gauge indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gauge needle will likely indicate a
higher temperature when driving in hot weather, up
mountain grades, in heavy traffic, or when towing a
trailer. If the needle rises to the“H”mark, stop the
vehicle, shift into N (Neutral), and increase the engine
idle speed for 2 to 3 minutes. If the temperature reading
does not return to normal, shut your engine OFF and
allow it to cool. Seek authorized service immediately. See
Cooling System information in the section on“Maintain-
ing Your Vehicle.”
NOTE:If the gauge pointer moves to either extreme of
the gauge, the“Check Gages”indicator will illuminate
and a single chime will sound.

snowflake button shows that the air conditioning is on.
Press the button a second time to turn the air condition-
ing off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
The mode control (at the right of the
control panel) can be set in any of the
following positions:
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.Recirculation Modes (Panel or Bi-Level )
Select the recirculation modes when
the outside air contains smoke, odors,
high humidity, or if rapid cooling is
desired. This feature allows for recir-
culation of interior air only. Air flows
through the panel only or through
both the panel and floor vents depend-
ing on the selected mode (panel vs bi-level).
NOTE:Selecting a“Recirculation Mode”mode does not
necessarily consume more fuel than normal A/C mode.
Panel
Outside air flows through the outlets located in the
instrument panel.
Bi-Level
Outside air flows through the outlets located in the
instrument panel and at the floor.

speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation isencountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

crossing is the water depth, current and bottom con-
ditions. On soft bottoms the vehicle will sink in,
effectively increasing the water level on the vehicle. Be
sure to consider this when determining the depth and
the ability to safely cross.
•Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water–Puddles, pools, flooded or other
standing water areas normally contain murky or
muddy waters. These water types normally contain
hidden obstacles and make it difficult to determine an
accurate water depth, approach angle, and bottom
condition. Murky or muddy water holes are where
you want to hook up tow straps prior to entering. This
makes for a faster, cleaner and easier vehicle recovery.
If you are able to determine you can safely cross, than
proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effec-
tiveness by depositing debris onto the radiator.
•Crossing Ditches, Streams, Shallow Rivers Or Other
Flowing Water–Flowing water can be extremely
dangerous. Never attempt to cross a fast running
stream or river even in shallow water. Fast moving
water can easily push your vehicle downstream
sweeping it out of control. Even in very shallow water,
a high current can still wash the dirt out from around
your tires putting you and your vehicle in jeopardy.
There is still a high risk of personal injury and vehicle
damage with slower water currents in depths greater
than the vehicle’s running ground clearance. You
should never attempt to cross flowing water which is
deeper than the vehicle’s running ground clearance.
Even the slowest current can push the heaviest vehicle

Trailer Towing Mirrors—If Equipped
These mirrors are designed with an adjustable mirror
head to provide a greater vision range when towing
extra-wide loads. To change position inboard or out-
board, the mirror head should be rotated (flipped Out or
In). A small blindspot mirror is integrated onto the main
mirror surface.
Cooling System Tips—Trailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
•City Driving—when stopped, put the transmission in
N (Neutral) and increase the engine idle speed.
•Highway Driving—reduce your speed.
326 STARTING AND OPERATING

•Air Conditioning—turn it off temporarily.
•Hilly Terrain—Turn overdrive off.
See Cooling System Operating information in the Service
and Maintenance section of this manual for more infor-
mation.
Automatic Transmission Oil Temperature Warning
Light
All vehicles with automatic transmissions are equipped
with a transmission sump oil temperature sensor and
warning light. If elevated transmission temperatures are
encountered, the engine controller will select the most
desirable gear until the transmission temperatures are
reduced. If transmission oil temperatures continue to
rise, a warning light located in the instrument cluster will
illuminate. If this should occur, stop the vehicle, shift to
Neutral, and run the engine at idle or faster until the light
goes off.
Towing With An Automatic Transmission
Vehicles equipped with an automatic transmission may
shift into and out of Overdrive, or a lower gear, when
driving in hilly areas, when heavily loaded, or when
towing into heavy winds.
When this condition occurs, select TOW/HAUL mode or
shift into a lower gear to prevent excessive transmission
wear and/or overheating, and to provide better engine
braking.
NOTE:Do not exceed the following RPM while manu-
ally downshifting:
•5600 rpm with 5.7L engines.
