2004 DODGE DAKOTA engine overheat

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
Dodge Dakota Models
NOTE:
Do not use Dodge Dakota Models for snow-
plow applications.
WARNING!
Snowplows, winches, and other aftermarket equip-
ment should not be added to the front end or your
vehicle. The airbag crash sensors may be affected by
the change in the front end structure. The airbags
could deploy unexpectedly or could fail to deploy
during a collision resulting in serious injury or
death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
STARTING AND OPERATING 201

WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
Engine Fuel Filter
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, frequent filter replacement may be necessary.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer's specifications, should be ob-
tained immediately.To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Maintenance-Free Battery
All Dodge trucks are equipped with maintenance-free
batteries. You will never have to add water, nor is
periodic maintenance required.
232 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.
