drain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Cooling System Ð Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the
intervals shown on the ªMaintenance Schedulesº in this
manual.
If the solution is dirty or contains a considerable amount
of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze solution.
Selection Of Coolant
Use only the manufacturer's recommended coolant. Re-
fer to ªFluids, Lubricants, and Genuine Partsº for the
correct coolant type.
CAUTION!
²Mixing of coolants other than specified HOAT
engine coolants, may result in engine damage and
may decrease corrosion protection. If a non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
²Do not use plain water alone or alcohol-base
engine coolant (antifreeze) products. Do not use
additional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant and may plug the radiator.
²This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended.
220 MAINTAINING YOUR VEHICLE

Adding Coolant
Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to 5 Years or 100,000 miles (160
000 km) before replacement. To prevent reducing this
extended maintenance period, it is important that you
use the same coolant throughout the life of your vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) coolant.
When adding coolant:
²The manufacturer recommends using Mopart
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
²Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below234ÉF (237ÉC) are
anticipated.
²Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
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 coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant recovery bottle.
MAINTAINING YOUR VEHICLE 221

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.
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.
MAINTAINING YOUR VEHICLE 225

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.
