2005 DODGE VIPER engine overheat

Trunk Ajar Light
This light indicates that the trunk is not latched.
Engine Coolant Temperature Light
A red LED light on the Coolant Temperature
gauge will illuminate to warn of an overheated
engine coolant condition.
Low Oil Pressure Light
A red LED light on the Oil Pressure gauge will
illuminate to indicate low engine oil pressure. The
light should come on briefly as a bulb check when the
engine is first started. If the light stays on or comes on
while driving, stop the vehicle and shut off the engine.
DO NOT operate the vehicle until the cause is corrected.
NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked under
the hood.
Charge System Light
A red LED light on the Voltage gauge will illumi-
nate when there is a charging system malfunction
or a possible accessory drive belt failure.
CAUTION!
The accessory belt also drives the water pump.
Operating the vehicle with a failed belt can cause
engine overheating and possible severe engine dam-
age.
Fog Light ON Indicator
This light indicates that the fog lights are on.
90 UNDERSTANDING YOUR INSTRUMENT PANEL

Materials Added to Fuel
All gasoline sold in the United States and Canada is
required to contain effective detergent additives. The use
of additional detergents or other additives is not needed
under normal conditions.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor orsome light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

HAZARD WARNING FLASHER
The flasher switch is on the top of the steering
column, just behind the steering wheel. Depress
the flasher button and all front and rear directional
signals will flash. Depress the flasher button again to turn
the 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.
NOTE:With extended use, the flasher may run 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.
•On the highways—Slow down and use the highest
gear possible.
•In city traffic—While stopped, put the transmission
in neutral, but do not increase engine idle speed.
Hazard Flasher Switch
148 WHAT TO DO IN EMERGENCIES

•In city traffic—While moving, shift into the highest
gear possible to reduce engine RPM.
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 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 cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
If your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to
call a service center for service. If you decide to look
under the hood yourself, see Section 7 of this
manual. Follow the warnings under the Radiator
Cap paragraph.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and First gear. Usually the least accelerator pedal pres-
sure to maintain the rocking motion without spinning the
wheels is most effective.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
TOWING A DISABLED VEHICLE
Do not tow with sling type equipment. Only use flat bed
equipment. Always comply with applicable state or local
towing ordinances.
CAUTION!
Towing with equipment other than flat bed types
may damage your vehicle.

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.

Cooling System
Inspection
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. Never try to
open a cooling system pressure cap when the radia-
tor is hot.
Coolant Checks
Check engine coolant (antifreeze) protection 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 the front of the radiator for any accumu-
lation of bugs, leaves, etc.
Check the coolant bottle tubing for condition and tight-
ness of connection at reserve tank and radiator. Inspect
the entire system for leaks.
NOTE:Check the front of the radiator for debris (leaves,
paper, etc.) regularly. A build up of such material could
lead to engine overheating.
Do not remove the cooling system pressure cap when the
cooling system is hot.
