Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.

[SV17850( ALL)05/95]
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in theMaintenance Schedule and Recordbooklet.

Add engine coolant only to the recovery
reservoir.If the coolant level is low, add a 50/50
or appropriate mixture of water and the type of
engine coolant that Ford specifies. You may add
water by itself only in an emergency, but you
should replace it with a 50/50 or appropriate
mixture as soon as possible.

Ford Premium Cooling System Fluid is an
optimized formula that will protect all metals
and rubber elastomers used in Ford engines for
four years or 50,000 miles (80,000 km). It is not
necessary and not recommended to use
supplemental coolant additives in your gasoline
powered vehicle. These additives may harm
your engine cooling system. Follow the
recommended service interval for changing your
engine coolant.
*
[SV19450( ALL)04/94]
NOTE: When you change or add engine
coolant, it is important to maintain
your engine coolant concentration
between 40%(-11ÊF [-24ÊC]) and 60%
(-62ÊF [-52ÊC]),depending on your local
climate conditions. Below 40% you will
lose freeze protection and above 60%
your engine may overheat on a warm
day.
[SV19460( ALL)12/94]
NOTE: The use of an improper coolant may
void your warranty for the engine
cooling system. Use only a premium
nationally recognized brand name
engine coolant. Do not use alcohol,
methanol antifreeze or engine coolant
mixed with alcohol or methanol
antifreeze. If you do not use the proper
coolant, the aluminum radiator on your
vehicle will corrode.

Ford Motor Company expressly authorizes the
Ford Rotunda engine coolant recycling process
and chemicals. Use only Ford Rotunda recycled
engine coolant or an equivalent recycled engine

Leave the engine coolant in all year. Make sure
that the coolant will not freeze at the
temperature level in which you drive during
winter months. Keep a mixture of engine coolant
in your engine that has a protection rating of at
least-34ÊF (-37ÊC), orwhatever protection rating
is appropriate for the climate in which you live.

Your vehicle may have a Motorcraft
maintenance-free battery. When the original
equipment battery is replaced under warranty, it
may be replaced by a Motorcraft
Low-Maintenance Battery.
*
[SV22130( ALL)02/95]
The Low-Maintenance Battery has removable
vent caps for checking the electrolyte level and
for adding water, if necessary. The electrolyte
level should be checked at least every 24 months
or 24,000 miles (40 000 km) in temperatures up
to 90ÊF (32ÊC) andmore often in temperatures
above90ÊF (32ÊC).Keep the electrolyte level in
each cell up to the level indicator. Do not
overfill.
*
[SV22145( ALL)02/95]
If the level gets low, you can add tap water to
the battery, provided the water isn't hard or
doesn't have a high mineral or alkali content.
However, if possible you should refill the battery
with distilled water. If the battery needs water
quite often, have the charging system checked
for a possible malfunction.

Because your vehicle's engine is electronically
controlled by a computer, some control
conditions are maintained by power from the
battery. If you ever disconnect the battery or
install a new battery, you must allow the
computer to ªrelearnº its idle conditions before
your vehicle will drive properly. To let the
engine do this, put the gearshift in P (Park), turn
off all the accessories, and start the vehicle. Let
the engine idle for at least one minute. (Engine
must be warm in order to ªlearn.º) Also, allow
approximately 10 miles (16 km) of stop and go
traffic for your vehicle's engine to completely
ªrelearnº its idle.

Check the level of the windshield washer fluid
periodically, or when the optional lamp indicates
low fluid. The reservoir for washer fluid is
located on the driver's side of the engine
compartment. Visual inspection can determine if
the washer fluid is adequate. Do not operate the
washer when the reservoir is empty.

RWARNING

[SV23500( ALL)01/95]
Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such
as methanol should be used in freezing weather
(temperatures below32ÊF [0ÊC]).State or local
regulations on Volatile Organic Compounds
(VOC's) may restrict use of the most common
antifreeze, methanol. Washer fluids containing
non-methanol antifreeze agents should be used
only if they provide cold weather protection
without damaging the vehicle's paint finish,
wiper blades, and windshield washer system.

Wiper Blades
*
[SV23700( ALL)03/95]
Check the windshield wiper blades at least twice
a year. Also check them whenever they seem
less effective than usual. Substances such as tree
sap and some hot wax treatments used by
commercial car washes reduce the effectiveness
of wiper blades.
*
[SV23800( ALL)03/95]
If the blades do not wipe properly, clean both
the windshield and the wiper blades. Use
undiluted windshield washer solution or a mild
detergent. Rinse thoroughly with clear water. Do
not use fuel, kerosene, paint thinner, or other
solvents to clean your wiper blades. These will
damage your blades.
*
[SV23900( ALL)03/95]
To make reaching the wiper blades easy, simply
turn the ignition to the ACC position and turn
your wipers on. Wait for them to reach a
vertical position and turn the ignition to the OFF
position. Do not move the wipers manually.
Manually moving the wipers across the
windshield may damage them.

Wiper blade replacement
*
[SV24100( ALL)03/95]
If the wiper blades still do not work properly
after you clean them, you may need to replace
the wiper blade assembly or the blade element.
When replacing the wiper blade assembly, blade
refill, or wiper arm always use a Motorcraft part
or equivalent. To replace the blades, follow the
instructions that come with them.
