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.

RWARNING
Never remove the radiator cap or vent
plug while the engine is running or hot.
[SV19030( ALL)05/95]
Follow these steps to avoid personal injury that
can be caused by escaping steam or engine
coolant.
[SV19040(MBC )03/95]
1. Before you remove the cap, turn the engine
off and let it cool. Even when the engine is
cool, be careful when you remove the
radiator cap or vent plug.
[SV19145( ALL)03/95]
2. When the engine is cool, wrap a thick towel
around the cap and turn it slowly
counterclockwise to unscrew.

[SV19150( ALL)03/95]
3. Step back while the pressure releases.
[SV19160( ALL)12/94]
4. When you are sure that all the pressure has
been released, use the cloth to press the cap
down, turn it, and remove it.

[SV19170(MBC )03/95]
5. Stand away from the radiator opening. Hot
steam may blow out or hot engine coolant
may even splash out.

To find out how much engine coolant mixture
your vehicle's coolant system can hold, seeRefill
capacities for fluidsin the Index.
% [SV19200( ALL)12/94]
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.
*
[SV19300( ALL)01/95]
Have your dealer check the engine cooling
system for leaks if you have to add more than a
quart (liter) of engine coolant more than once a
month.

Battery

[SV22100( ALL)02/95]
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.

the washer fluid is adequate. Do not operate the

Use specially formulated windshield washer

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

Wash the wheels with the same detergent you
use to wash your vehicle's body. Do not use
acid-based wheel cleaners, steel wool, abrasives,
fuel, or strong detergents. These substances will
damage protective coatings. Use tar and road oil
remover to remove grease and tar.

Automatic Transmission Fluid

[SV30475( ALL)01/95]
Under normal circumstances, you do not need to
check the fluid level of the transmission, since
your vehicle does not use up transmission fluid.
Refer to theMaintenance Schedule and Record
booklet for replacement intervals. However, if
the transmission is not working properly Ð for
instance, the transmission may slip or shift
slowly, or you may notice some sign of fluid
leakage Ð the fluid level should be checked.

Checking the Automatic Transmission
Fluid

[SV30560( ALL)02/95]
It is preferable to check the transmission fluid
level at normal operating temperature
150ÊF-170ÊF (66ÊC-77ÊC),after approximately
20 miles (30 km) of driving. However, if
necessary, you can check the fluid level without
having to drive 20 miles (30 km) to obtain a
normal operating temperature if outside
temperatures are above50ÊF (10ÊC).
[SV30575( ALL)03/94]
With the vehicle on a level surface, start the
engine and, while fully applying the brake
pedal, move the transmission shift selector
through all of the gear ranges allowing sufficient
time for each position to engage.Securely latch
the transmission shift selector in the P (Park)
position, fully set the parking brake and leave
the engine running.
