cooling DODGE DAKOTA 2004 3.G Owners Manual

INSTRUMENT CLUSTER DESCRIPTION
1. Engine Coolant Temperature Gage
The temperature gage indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is oper-
ating satisfactorily. The gage needle in V6 and V8
engines will likely indicate a high temperature when
driving in hot weather, up mountain grades, in heavy
traffic, or when towing a trailer. If the needle rises to
260É (hot mark), stop the vehicle, shift into N (Neutral)
and elevate engine speed for 2-3 minutes. If the
temperature reading does not return to normal, seek
authorized service immediately.
CAUTION!
Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
The gage pointer will remain near its last reading when
the engine is turned off. It will return to a true reading
when the engine is restarted.
2. Voltage Gage ± If Equipped
When the engine is running, the gage will
indicate the electrical system voltage. During
normal electrical load, the pointer will remain near the
center of the scale. If the pointer moves to either the
high or low sections, and remains there during normal
driving, the electrical system should be serviced.
3. Tachometer
This gage measures engine revolutions per minute (rpm
x 1000).
4. Shift Indicator Light
A small triangle lights to signal the most economical shift
point for vehicles equipped with a manual transmission.
See the Manual Transmission Operating description in
section 5 of this manual for details.
5. Turn Signal Indicators
When a turn signal is activated, a right-pointing or
left-pointing arrow lights up and flashes to indicate the

U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button.
27. Cruise Light
This indicator lights when the electronic speed control
system is turned on.
28. Coolant Temperature Light (Clusters Without A
Gauge)
This light warns of an overheated engine con-
dition. For a bulb check, this light will come on
momentarily when the ignition is turned On. If
the light turns on while driving, stop the vehicle and
shut off the engine as soon as possible.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the light turns
off. If the if the light remains on, turn the engine off
immediately, and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
104 INSTRUMENT PANEL AND CONTROLS

Air Conditioning Operation
To turn on the Air Conditioning, set the fan control at any
speed and press the snowflake button located at the right
of the control panel. Conditioned air will be directed
through the outlets selected by the mode control. A light
in the snowflake button shows that the air conditioning is
on. Press the button a second time to turn the air
conditioning off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is anormal 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 outlets in this mode.

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.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 is
encountered, operate the transmission in a lower gear.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and depress the accelerator slightly
for fast idle operation.
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.

Cooling System TipsÐTrailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
²City DrivingÐWhen stopped for short periods of
time, put transmission in neutral and increase engine
idle speed.
²Highway DrivingÐReduce your speed.
²Air ConditioningÐTurn off temporarily.
See Cooling System Operating information in the Main-
tenance section of this manual for more information.
To reduce potential for automatic transmission overheat-
ing, turn the Overdrive OFF when driving in hilly areas
or shift the transmission to Drive position 2 on more
severe grades. Move the shift lever to the next lower
position to eliminate excessive transmission shifting. This
action will also reduce the possibility of transmission
overheating and provide better engine braking.
NOTE:If your vehicle has an automatic transmission
and you tow a trailer frequently follow Maintenance
Schedule ªBº.
SNOWPLOW

220 MAINTAINING YOUR VEHICLE

Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, fol-
low the preceding safety tips.
Cooling System
Inspection
Coolant protection checks should be made at every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check face of radiator for any accumulation of
bugs, leaves, etc. If dirty, clean the radiator core by gently
spraying water from a garden hose at the back of the core.
Check the reserve tank tubing for condition and tightness
of connection at reserve tank and radiator. Inspect the
entire system for leaks.
With the engine at normal operating temperature (but
not running), check the coolant pressure cap for proper
vacuum sealing by draining a small amount of coolant
from the radiator drain cock. If the cap is sealing prop-
erly, the coolant will begin to drain from the reserve tank.
Do not remove the pressure cap when the cooling system
is hot.

WARNING!
You or others can be badly burned by hot coolant or
steam from your radiator. If you see or hear steam
coming from under the hood don't open the hood
until the radiator has had time to cool. If you open
the hood and see steam or hot coolant escaping from
the radiator, don't touch anything. Get away quickly.
Never try to open a pressure cap when the radiator is
hot.
Cooling System Maintenance
At the intervals shown on the Maintenance Schedules,
the system should be drained, flushed and filled.
Cooling System Ð Drain, Flush And Refill
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Discard old antifreeze
solution according to recommended procedure.
Disposal of Used Engine Coolant
Used ethylene glycol-based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol-based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals and
children. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Recommended Engine Coolant
Refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type.
238 MAINTAINING YOUR VEHICLE

CAUTION!
Mixing of coolants other than specified (non-
HOAT), may result in engine damage that may not
be covered under the new vehicle warranty, and
decreased corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.
Do not use plain water alone or alcohol base anti-
freeze products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compat-
ible with the radiator coolant and may plug the
radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
When adding coolant or refilling system, a 50% solution
of ethylene glycol antifreeze coolant in water should beused. Higher concentrations (not to exceed 65%) are
required if temperatures below ±37ÉF (± 38ÉC) are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water/antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
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.
