2008 DODGE VIPER coolant

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
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 scald-
ing 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 en-
gine damage may result.
Disposal of Used 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
222 MAINTAINING YOUR VEHICLE

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.
²Do not overfill the coolant recovery bottle.
²Check coolant freeze point in the coolant bottle. If
antifreeze needs to be added, contents of the coolant
bottle also must be protected against freezing.
²If 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.
²Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine, which contains
aluminum components.
²Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.

²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling suggest deterioration of the rub-
ber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component, which may cause heat
damage or mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed.Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could result in failure.Fuel System
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.

VEHICLE STORAGE
We recommend that you follow these guidelines for
storing your vehicle for extended periods.
²Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than 2 months, add an anti-oxidant fuel stabilizer to
the fuel tank.
²Change the oil to remove any corrosive combustion
related acids in the crankcase.
²Check that the radiator coolant level of protection is to
at least -20ÉF (-29ÉC).
²Make sure that all tires are inflated to the optimum
pressure. (See page 158 for more information.)
²Wash and wax the vehicle to protect the finish.
²Store the vehicle in a dry, well-ventilated location.
²Move the wiper blades away from the windshield.
²Block the wheels. Do not apply the Parking Brake.
²Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
²For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
²If the vehicle will be subjected to freezing tempera-
tures, either remove the battery and store it in a dry,
well ventilated area or connect a trickle charger (1.5
Amp) with automatic shutdown / overcharge protec-
tion to the battery. However, do not leave the trickle
charger hooked up to the battery without being
plugged in to a 110 volt AC outlet, as 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, perform the
battery recharge procedure in the Service Manual.

HEADLIGHT AIMING
The headlights on your new vehicle were aimed at the
factory under a no load setting. A great increase in weight
will change the aiming of the headlights. Therefore, it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the rear
compartment or generally suspect misalignment. In ei-
ther case, see your authorized dealer if the headlights
require adjustment.

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery, and clean and tighten the terminals
as required.
²Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering, and transmission,
and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
NOTE:Also, inspect the exhaust system if you notice a
change in the sound of the exhaust system, or if the
exhaust fumes can be detected inside the vehicle.
²Inspect the brake hoses.
²Inspect the suspension components.
²Lubricate door hinges and check springs.
²Check the engine coolant level, hoses, and clamps.
²Check power steering fluid level.
