2008 DODGE VIPER Owners Manual

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.
224 MAINTAINING YOUR VEHICLE

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Recommended service intervals can be found in the
ªMaintenance Schedulesº in this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
Brake and Power Steering 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.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:
²Often, fluid such as oil, power steering fluid, and
brake fluid are used during assembly plant operations
to facilitate the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping
of hot fluid when systems are under pressure (during
vehicle operation), should be noted before a hose is
replaced based on leakage.

²Inspect the brake hoses whenever the brake system is
serviced and at every engine oil change. Inspect hy-
draulic brake hoses for surface cracking, scuffing, or
worn spots. 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 resulting in a possibility of a burst failure.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
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.
226 MAINTAINING YOUR VEHICLE

Use only the manufacturer's recommended brake fluid.
Refer to ªFluids, Lubricants, and Genuine Partsº for the
correct fluid type. Use of a brake fluid that may have a
lower initial boiling point or unidentified as to specifica-
tion, 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!
²Do not allow petroleum base fluid to contaminate
the brake fluid, all brake seal components could
be damaged causing partial or complete brake
failure.
²Brake fluid can damage the finish of your vehicle.
Do not allow brake fluid to contact any painted
surface.
Change Brake Fluid
Brake fluid will tend to absorb moisture from the atmo-
sphere over time. If the fluid becomes contaminated with
water, brake performance will deteriorate. Therefore, the
brake fluid must be changed at the intervals specified in
the ªMaintenance Schedulesº in this manual. See your
authorized dealer for service.

Transmission
Transmission Fluid Level Check
Check the fluid in the transmission when performing
other underhood services.
Check the fluid level by removing the fill plug located on
the left side of the transmission. The fluid level should be
at the bottom of the fill hole. Add fluid, if necessary, to
maintain the proper level. Refer to the ªFluids, Lubri-
cants, and Genuine Partsº for the correct fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turer's recommended fluid may cause deterioration
in transmission shift quality and/or damage to the
transmission. Refer to the ªFluids, Lubricants, and
Genuine Partsº for the correct fluid type.
Change Transmission Fluid
Change the fluid at the intervals specified in the Main-
tenance Schedules in this manual. If contaminated with
water, change the fluid immediately. See your authorized
dealer for service.
Hydraulic Clutch
Master Cylinder Ð Clutch Fluid Level Check
Check the fluid in the clutch master cylinder when
performing underhood services.
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.
228 MAINTAINING YOUR VEHICLE

Use only the manufacturer's recommended clutch fluid.
Refer to ªFluids, Lubricants, and Genuine Partsº 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!
²Do not allow petroleum base fluid to contaminate
the clutch fluid, all clutch seal components could
be damaged causing partial or complete clutch
failure.
²Clutch 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 the ªMaintenance Schedulesº in this manu-
al.See your authorized dealer for service.

Rear Axle
Axle Lubricant Level Check
Check the exterior of the axle for evidence of gear oil
leakage every 12 months or 6,000 miles (10 000 km). This
check should be made with the vehicle level and sup-
ported by the suspension, with the vehicle on the ground
or raised on an axle and wheel type hoist. The axle
lubricant level should be between the bottom of the filler
plug and a point approximately 3/8 inch (9.5 mm) below
the filler plug. If adding axle lubricant, use only the
manufacturer's recommended axle lubricant. Refer to the
ªFluids, Lubricants, and Genuine Partsº for the correct
fluid type.
NOTE:The Limited Slip Differential requires that a
friction control additive be added when draining and
refilling the axle lubricant.
Change Axle Lubricant
Drain and fill the axle at the intervals specified in the
ªMaintenance Schedulesº in this manual. Change the
lubricant immediately if contaminated with water. See
your authorized dealer for service.
Wheel Bearings
The wheel bearings are permanently sealed. No regular
maintenance is required for these components.
Appearance Care and Protection from Corrosion
Your manufacturer's dealer offers a complete line of
products for cleaning your vehicle. Follow the instruc-
tions on each container.
Commercial Car Washes
We do not recommend taking this vehicle through a
commercial car wash.
230 MAINTAINING YOUR VEHICLE

In the event that you do take this vehicle to a commercial
car wash, move the Heater/Air Conditioning blower
control to the lowest setting. This will prevent the possi-
bility of water entering the system.
CAUTION!
The tires on this vehicle are wider than the guide
tracks on most washes and the low ground clearance
of this vehicle may not be compatible with some car
wash equipment. You could damage your vehicle.
Paint and Trim
Your vehicle is exposed to the corrosive effects of chemi-
cal fallout, salt spray, and road film. To protect not only
the paint and trim, but also exposed mountings and
fixtures, it is important to wash your vehicle often and
thoroughly.After washing, allow all surfaces to drain and dry before
parking the vehicle in a closed garage. Prompt washing
may not thoroughly remove these deposits. Additional
cleaners may be required. When using chemical cleaners
formulated for this purpose, be certain they are safe for
use on urethane painted surfaces.
Use soap and water on dull black window trim. Polish or
cleaners may leave a white residue. If desired, you may
polish your vehicle immediately by using MopartAuto-
mobile Polish or equivalent.
Damage to the Body Finish
Any stone chips, fractures or deep scratches in the finish
should be promptly repaired.
Minor damage can be repaired by using touch-up mate-
rials available at your dealer. More extensive damage
should be corrected in your dealer's paint facility.
