2006 DODGE VIPER engine

WARNING!
•The warning words “DO NOT OPEN HOT” 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.
•Do 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 childrendo 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
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check coolant freeze point in the coolant bottle. If
antifreeze needs to be added, contents of the coolant
bottle also must be protected against freezing.
•If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
•Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine which contains
aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.

Brake, Power Steering, and Fuel System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasion, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be made to examining those hose sur-
faces nearest to high heat sources, such as the exhaust
manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids are used during assembly plant
operations to ease the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping ofhot fluid when systems are under pressure (during
vehicle operation) should be noted before hose is re-
placed based on leakage.
High pressure fuel system hoses have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
Use only manufacturer specified hoses or their equiva-
lent in material and specification, in any fuel system
servicing. It is mandatory to replace all clamps that have
been loosened or removed during service.
NOTE:Inspection of brake hoses should be done when-
ever the brake system is serviced and at every engine oil
change. If there is any evidence of cracking, scuffing, or
worn spots, the hose should be replaced immediately!
Eventual deterioration of the hose can take place with
possible burst failure.

Brake and Clutch Fluid
These fluids will tend to absorb moisture from the
atmosphere over a period of time. If the fluid becomes
contaminated with water, brake or clutch performance
will deteriorate. The brake and clutch fluid must be
changed every two years.
CAUTION!
Brake fluid can damage the finish of your Viper. Do
not allow brake fluid to contact any painted surface.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Master Cylinder
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning lamp shows system failure. Be
sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However, low
fluid level may be caused by a leak and a checkup may be
needed. Use only the manufacturer’s recommended
brake fluid. Refer to the Recommended Fluids, Lubri-
cants and Genuine Parts section for the correct fluid type.
Mopar Brake Fluid or equivalent is fluid of this quality
and is recommended to provide best brake performance.
Use of a brake fluid that may have a lower initial boiling
point or unidentified as to specification, may result in
sudden brake failure during hard prolonged braking.

CAUTION!
The tires on your Viper are wider than the guide
tracks on most washes and the low ground clearance
of your vehicle may not be compatible with some car
wash equipment. You could damage your vehicle.
FUSES — Power Distribution Center
A power distribution center is located in the engine
compartment. This center contains fuses and relays.

•If the vehicle will be subjected to freezing tempera-
tures, remove the battery and store it in a dry, well
ventilated area or place a trickle charger (1.5 Amp)
with automatic shutdown / overcharge protection
connected to the battery. Do not leave the trickle
charger hooked up to the battery without being
plugged into the 110 AC voltage outlet, because this
will result in further drain on the vehicle’s battery. If
the vehicle is not going to be driven in the next 3
weeks, follow the battery recharge procedure in the
Service Manual, then disconnect the battery at the
negative terminal or use the save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery.CAUTION!
Use care when disconnecting the remote positive
cable. It is connected to the battery and can short out
to any metal on the vehicle. Always tape or wrap the
exposed cable end to prevent electrical shorts.
•Disconnecting the battery causes the engine control
system to lose memory of some “learned” functions,
unless using the Battery Save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery. The engine may run rough when first
started after a battery disconnect until the control
module “relearns” these functions.
