engine DODGE VIPER 2009 ZB II / 2.G Repair Manual

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified HOAT engine coolant (antifreeze), may
result in engine damage and may decrease corro-
sion protection. If a non-HOAT engine coolant
(antifreeze) is introduced into the cooling system
in an emergency, it should be replaced with the
specified engine coolant (antifreeze) as soon as
possible.
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator engine
coolant (antifreeze) and may plug the radiator.
(Continued)
CAUTION! (Continued)
•This vehicle has not been designed for use with
Propylene Glycol based engine coolant (anti-
freeze). Use of Propylene Glycol based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to five years or 100,000 miles (160 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze).
218 MAINTAINING YOUR VEHICLE

When adding engine coolant (antifreeze):
•The manufacturer recommends using MOPAR
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
•Mix a minimum solution of 50% HOAT engine coolant
(antifreeze) and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below34°F
(37°C) are anticipated.
•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(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.NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent engine coolant (antifreeze)
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to insure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
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 en-
gine damage may result.
Disposal of Used Coolant
Used ethylene glycol based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposalrules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol based
engine coolant (antifreeze) 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 engine coolant (antifreeze) level is
adequate. With the engine idling, and warm to normal
operating temperature, the level of the engine coolant
(antifreeze) 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
engine coolant (antifreeze) freeze point or replacing en-
gine coolant (antifreeze). Advise your service attendant
220 MAINTAINING YOUR VEHICLE

of this. As long as the engine operating temperature is
satisfactory, the coolant bottle need only be checked once
a month.
When additional engine coolant (antifreeze) 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
(kilometers) of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) 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 engine coolant (antifreeze) freeze point in the
coolant bottle. If engine coolant (antifreeze) needs to
be added, contents of the coolant bottle also must be
protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (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.

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 reser-
voir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
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 “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type. 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.WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
CAUTION!
•Do not allow petroleum base fluid to contaminate
the brake fluid, all brake seal components could
be damaged causing partial or complete brake
failure.
•Brake fluid can damage the finish of your vehicle.
Do not allow brake fluid to contact any painted
surface.

Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to the reservoir.
Do Not Overfill. Overfilling can cause clutch release
problems as the clutch wears. A low fluid level may
indicate a leak, in which case, hydraulic clutch linkage
replacement may be required. The fluid level in the
reservoir will rise as the clutch wears - do not remove
fluid.
Use only the manufacturer’s recommended clutch fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
WARNING!
Overfilling the clutch fluid reservoir can result in
spilling clutch fluid on hot engine parts and the
clutch fluid catching fire.Use only clutch fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
CAUTION!
•Do not allow petroleum base fluid to contaminate
the clutch fluid, all clutch seal components could
be damaged causing partial or complete clutch
failure.
•Clutch fluid can damage the finish of your vehicle.
Do not allow clutch fluid to contact any painted
surface.
Change Clutch Fluid
Clutch fluid will tend to absorb moisture from the
atmosphere over time. If the fluid becomes contaminated
with water, clutch performance will deteriorate. There-
fore, the clutch fluid must be changed at the intervals
specified in “Maintenance Schedules” in Section 8 of this
manual. See your authorized dealer for service.

Then, either disconnect the battery at the negative
terminal or use the “Battery Save Feature” to conserve
battery power. Refer to “Battery Save Feature” under
“Maintenance Procedures” in this section for details.
NOTE:Disconnecting the battery causes the engine
control system to lose memory of some “learned” func-
tions. After reconnecting the battery, the engine may run
rough until the control module “relearns” these func-
tions. Using the Battery Save Feature will prevent the
engine controller from loosing its memory.
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.Check the battery every four to six weeks to ensure that
the voltage is above 12.40 Volts. The voltage will drop
more rapidly in hot temperatures. If battery voltage
drops below 12.40 Volts, follow the battery recharge
procedure in the Service Manual.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the trunk/liftgate, hood, doors, win-
dows, and convertible top are completely closed.
2. Make sure that Remote Keyless Entry (RKE) transmit-
ter is operating and that the battery is good.
3. Make sure that the HOOD, TRUNK/LIFTGATE, and
DOOR switches are in adjustment. Perform the quick
system check, which follows:
Use the remote transmitter to set the alarm. If the alarm
SET light comes on and flashes, the system is operating
