engine coolant 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

12. Seat Belt Reminder Light
This light comes on for several seconds after the
ignition is turned ON as a reminder to ªbuckle
up.º This light will remain on as long as the seat
belt remains unbuckled. If this light flashes, it indi-
cates a fault in the airbag system. Have the system
checked by an authorized dealer.
13. Low Washer Fluid Indicator
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
14. Brake System Warning Light
This light will light when the ignition key is turned to the
ON position and will remain on for a few seconds. If the
light stays on, it may be an indication that the parking
brake has not been released, or there is a low brake fluid
level. If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full mark on
the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction. In this case, the light will
remain on until the cause is corrected. If the parking
brake is applied, the light will flash when the gearposition is out of park for automatic transmissions, or the
engine RPM is greater than 0 for manual transmissions.
If brake failure is indicated, immediate repair is neces-
sary.Operating the vehicle in this condition is danger-
ous!
15. SERVICE 4WD Indicator
This light monitors the electric shift 4WD
system. This light will come on when the
ignition key is turned to the ON position and
will stay on for 2 seconds. If the light stays
on or comes on during driving, it means that the 4WD
system is not functioning properly and that service is
required.
16. Check Gages
This light illuminates when the Voltmeter, En-
gine Oil Pressure or Engine Coolant Tempera-
ture gages indicate a reading either too high or too
low. Examine the gages carefully, and follow the
instructions above for each indicated problem.

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.

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.
138 INSTRUMENT PANEL AND CONTROLS

CAUTION!
Long periods of engine idling can cause excessive
exhaust temperatures which can damage your ve-
hicle. Do not leave your vehicle unattended with the
engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Engine Block Heater Ð If Equipped
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord.
The engine block heater cord is located at the right front
of the engine compartment for all engine applications.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
SHIFTING
Automatic Transmission
The gear shift lever is mounted on the right side of the
steering column. To engage a gear for driving, move the
shift lever from P-Park or N-Neutral to the desired gear
range (R-Reverse, D-Drive, 2±Second, or 1±First). To
move the shift lever, pull it toward you, then release it
when the desired gear range is reached. The Transmis-
sion Range Indicator (labeled ªGear Selectorº) in the
instrument cluster shows the selected gear range. The
Indicator is illuminated for night driving.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
146 STARTING AND OPERATING

ªNº Neutral
Shift to Neutral when vehicle is standing for prolonged
periods with engine running. Engine may be started in
this range. Set the parking brake if you must leave the
vehicle.
ªDº Drive
Use this position for most city and highway driving.
ª2º Second
Use this position for driving slowly in heavy city traffic
or on mountain roads where more precise speed control
is desirable. Use it also when climbing long grades, and
for engine braking when descending moderately steep
grades. To prevent excessive engine speed do not exceed
45 mph (72 km/h) in this range.
ª1º First
Use this position for driving up very steep hills and for
engine braking at low speeds 25 mph (40 km/h ) or less
when going down hill. To prevent excessive engine speed
do not exceed 25 mph (40 km/h) in this range.
Overdrive
The transmission contains a fourth and fifth (if equipped)
speed (Overdrive) and will automatically shift from
Drive to Overdrive if the following conditions are
present:
²The transmission selector is in Drive.
²Engine coolant has reached normal operating tem-
perature.
²Vehicle speed is above approximately 30 mph (48
km/h).
²The ªO/D OFFº button has not been activated.
²Transmission has reached normal operating tempera-
ture.
Overdrive can be locked out by pressing the O/D Off
button located at the end of the transmission gear shift
lever. A light in the instrument cluster shows that the
feature has been deactivated. Pressing the button a
second time restores the Overdrive function.
148 STARTING AND OPERATING

the vehicle speed drops below a calibrated speed, or
during acceleration, the clutch automatically and
smoothly disengages. The feature is operational in Over-
drive and in Drive.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Pressing the O/D OFF button, when the transmission is
sufficiently warm, will demonstrate that the transmission
is able to shift into and out of overdrive.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due to
the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
Manual Transmission
NOTE:
The parking brake should be engaged before
leaving the vehicle, especially on an incline.
Use each gear in numerical order - do
not skip a gear. Be sure the transmission
is in FIRST gearÐ not THIRD, when
starting from a standing position; other-
wise damage to the clutch can result
from starting in THIRD.
For most city driving you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, 5th gear is recommended. To shift into 5th
gear, move the shift lever to the right beyond the spring
pressure point and push it forward. When shifting from
5th to 4th gear, pull the lever down toward you in one
motion. Do not pull the lever sharply left as you may
shift accidentally into 2nd gear and damage the trans-
mission or engine.
150 STARTING AND OPERATING

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.
