best engine performance, fuel economy and
engine protection for all climates down to-15ÊF
(-25ÊC).

Synthetic engine oils which are CERTIFIED and
of the preferred viscosity may be used in your

Checking and Adding Engine Oil
*
[SV13800( ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.
%*
[SV13900( ALL)04/95]
Checking the engine oil level:
*
[SV14000( ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14025( BCGV)03/95]
2. Set the parking brake, making sure the
gearshift is securely latched in P (Park).
*
[SV14100( ALL)02/95]
3. Open the hood. Protect yourself from engine
heat.
*
[SV14200( ALL)03/95]
4. Locate the engine oil dipstick (highlighted in
yellow) and carefully pull it out of the
engine.

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QTº line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in Full, engine damage
or high oil consumption may occur and
some oil must be removed from the engine.

[SV14800( ALL)01/95]
It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.
*
[SV15000( ALL)03/95]
Add engine oil through the oil filler cap
highlighted in yellow. To add oil, remove the
filler cap and use a funnel to pour oil into the
opening. Be careful not to overfill the engine.
Recheck the oil level after you finish adding oil.

The cooling fan is automatic and may
come on at any time. Always disconnect
the negative terminal of the battery before

[SV17800( ALL)05/94]
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.

Never remove the pressure cap 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.
*
[SV19060( GV)01/95]
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
pressure cap.
[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]

been released, use the cloth to press the cap
down, turn it, and remove it.

[SV19175( GV)02/95]
5. Stand away from the reservoir 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.

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

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.

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.

Brake Fluid
*
[SV32000( ALL)04/95]
Under normal circumstances, your vehicle
should not use up brake fluid rapidly. However,
expect the level of the brake fluid to slowly fall
as you put more mileage on your vehicle and
the brake lining wears.
[SV32200( BCGV)03/95]
Check the brake fluid at each scheduled engine
oil change or at least once a year. You can do
this by looking at the fluid level in the plastic
reservoir on the master cylinder. Also, see label
on reservoir cap. (To locate the master cylinder,
seeThe Engine Typesin the Index.) The fluid
level should be between the MIN and MAX
marks.
*
[SV32350( ALL)05/95]
RWARNING
Brake fluid is toxic.
*
[SV32375( ALL)05/95]
If brake fluid contacts eyes, flush eyes with
running water for 15 minutes. Get medical
attention if irritation persists. If taken internally,
drink water and induce vomiting. Get medical
attention immediately.
