2005 DODGE NEON engine overheat

19. Door Ajar Indicator
This vacuum fluorescent display indicator illuminates
when a door is not completely closed. If the door is open
for more than 8 minutes and the ignition key is in the
OFF position, the indicator will turn off.
20. Trip Indicator
This light will illuminate when the Trip Odometer is in
use.
21. Cruise Light Ð If Equipped
This indicator shows that the Speed Control
System is ON. (See page 65 for more infor-
mation.)
NOTE:
The word ªSETºwill notilluminate when the
Speed Control System is on.
22. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading between the light
blue and red areas of the gauge shows that the
engine cooling system is operating properly. Thegauge pointer may show a higher than normal tem-
perature when driving in hot weather, up mountain
grades, in heavy stop and go traffic, or when towing a
trailer.
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. Pull off the road at a safe area.
With the vehicle in Park, idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on theH(red)
mark, turn the ignition off immediately and call for
service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning is
on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.

MMT in Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasolines
blended with MMT provide no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT have shown to reduce
spark plug life and reduce emission system performance in
some vehicles. The manufacturer recommends that gaso-
lines free of MMT be used in your vehicle. The MMT
content of gasoline may not be indicated on the gasoline
pump, therefore you should ask your gasoline retailer
whether or not his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at higher
levels than allowed in the United States.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normalconditions and would result in unnecessary cost. There-
fore you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.

HAZARD WARNING FLASHER
The flasher switch is on top of the steering column,
just behind the steering wheel. Depress the switch
and both cluster indicators and all front and rear direc-
tional signals will flash. Depress the switch again to turn
Hazard Warning Flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may wear down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, put transaxle in
neutral, but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature

the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the ªHº, 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, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.

CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transaxle overheating and failure. It can
also damage the tires. Do not spin the wheels above
35 mph (55km/h).
TOWING A DISABLED VEHICLE
With Ignition Key
Four Speed Automatic Transaxle
Your vehicle may be towed under the following condi-
tions: The steering column must be unlocked and the
gear selector must be in NEUTRAL, the distance to be
towed must not exceed 100 miles (160 km), and the
towing speed must not exceed 44 mph (72 km/h). If the
transaxle is not operative, or if the vehicle is to be towed
more than 100 miles (160 km), the vehicle must be towed
with the front wheels off the ground to avoid damage to
the transaxle.
Manual Transaxle
Your vehicle may be towed if the gearshift lever is in
NEUTRAL. If the transaxle is not operative, the vehicle
must be towed with the front wheels off the ground.
All Transaxles
CAUTION!
If the vehicle being towed requires steering, the
ignition switch must be in the OFF position, not in
the LOCK or ACCESSORY positions.
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACCESSORY position. Make certain the
transaxle remains in NEUTRAL.
160 WHAT TO DO IN EMERGENCIES

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.
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 suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected for prolonged period.
Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
174 MAINTAINING YOUR VEHICLE

WARNING!
²The warning words ªDO NOT OPEN HOTº on
the cooling system pressure cap are a safety pre-
caution. Never add coolant 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.
²Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
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. To prevent ingestion by animals or children
do not store ethylene glycol based engine coolant in open
containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine idling, and warm to normal operating tempera-
ture, the level of the coolant in the bottle should be
between the ranges indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine operating
temperature is satisfactory, the coolant bottle need only
be checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles (a
few kilometers) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
