ENGINE COOLANT
Check the level of the coolant in the
reservoir at least once a month. Be
sure to read and understand
Precautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked for a long period of time, the
engine coolant reservoir may eventually empty. If this occurs, add engine
coolant to the coolant reservoir. For more information on engine coolant
maintenance, refer toAdding engine coolantin this chapter.
Automotive fluids are not interchangeable; do not use engine coolant,
antifreeze or windshield washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
Do not put engine coolant in the container for the windshield
washer fluid.
If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.
When the engine is cool, add a 50/50 mixture of engine coolant and
water to the engine coolant recovery reservoir-DO NOT ADD DIRECTLY
TO THE RADIATOR. Add straight water only in an emergency, but you
should replace it with a 50/50 mixture of coolant and distilled water as
soon as possible.
Check the coolant level in the coolant recovery reservoir the next few
times you drive the vehicle. If necessary, add enough of a 50/50 mixture
of coolant and water to bring the liquid level to the fill line on the
reservoir.
Maintenance and care
130

Never remove the coolant recovery cap while the engine is
running or hot.
If you must remove the coolant recovery cap, follow these steps to avoid
personal injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Use Ford Premium Cooling System Fluid E2FZ-19549±AA (in Canada,
Motorcraft CXC-8±B) or an equivalent premium engine coolant that
meets Ford specification ESE-M97B44±A. Ford Premium Engine Coolant
is an optimized formula that will protect all metals and rubber elastomers
used in Ford cooling systems for four years or 80,000 km (50,000 miles).
Do not use alcohol or methanol antifreeze or any engine coolants mixed
with alcohol or methanol antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm your engine cooling
system. The use of an improper coolant may void your warranty of your
vehicle's engine cooling system.
Recycled engine coolant
Ford Motor Company recommends that Ford and Lincoln-Mercury
dealers use recycled engine coolant produced by Ford-approved
processes. Not all coolant recycling processes produce coolant which
meets Ford specification ESE-M97B44±A, and use of such coolant may
harm engine and cooling system components.
Always dispose of used automotive fluids in a responsible manner.
Follow your community's regulations and standards for recycling and
disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle's cooling system can hold, refer
toRefill capacitiesin theCapacities and specificationschapter.
Have your dealer check the engine cooling system for leaks if you have
to add more than a liter (quart) of engine coolant per month.
Maintenance and care
131

Severe winter climate
If you drive in extremely cold climates (less than ±36ÉC [±34ÉF]), it may
be necessary to increase the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the coolant concentration in
your vehicle is such that the coolant will not freeze at the temperature
level in which you drive during winter months. Never increase the engine
coolant concentration above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in non-extreme climates.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid at
least twice a year. If adding fluid is
necessary, use only MERCONtAT F
power steering fluid.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge will be near the
center of the NORMAL band).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.

If your vehicle has been operated for an extended period at high speeds,
in city traffic during hot weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow the fluid to cool before
checking.
1. Park the vehicle on a level surface and engage the parking brake.
2. With the parking brake engaged
and your foot on the brake pedal,
start the engine and move the
gearshift lever through all of the
gear ranges. Allow sufficient time
for each gear to engage.
3. Latch the gearshift lever in P
(Park) and leave the engine running.
4. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
5. Install the dipstick making sure it is fully seated in the filler tube.
6. Remove the dipstick and inspect the fluid level. The fluid level should
be within the top notch (hot) area of the dipstick.
7. If necessary, add fluid in .25L (1/2 pint) increments through the filler
tube until the level is correct.
8. If an overfill occurs, excess fluid should be removed by a qualified
technician.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
If the fluid level is above the top
notch of the hot range after driving
the vehicle approximately 30 km
(20 miles), excess fluid should be
removed by a qualified technician.

BATTERY
Your vehicle may be equipped with a
Superstart maintenance-free battery.
If the original equipment battery
needs replacing, it may be replaced
with a low-maintenance battery. The
low-maintenance battery normally
does not require additional water
during its life of service. However,
for severe usage or in high
temperature climates, check your
battery electrolyte level, at least
every 24 months or 40,000 km
(24,000 miles). Keep the electrolyte
in each cell up to the ªlevelº indicator. Do not overfill the battery cells.
If the electrolyte level in the battery is low, you can add plain tap water
to the battery, as long as you do not use hard water (water with a high
alkali content). If possible, however, try to only fill the battery cells with
distilled water. If the battery needs water often, have the charging
system checked.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminal(s) and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water. Reinstall the cables when
you are done cleaning them, and apply a small quantity of grease to the
top of each battery terminal to help prevent corrosion.
If your battery has a cover/shield, make sure it is reinstalled
after the battery is replaced.
Because your vehicle's engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle conditions before your vehicle will drive properly. To
begin this process:
1. Put the gearshift in P (Park), turn off all accessories and start the
vehicle.
2. Let the engine idle for at least one minute.
Maintenance and care
135

3. The relearning process will automatically complete as you drive the
vehicle.
²If you do not allow the engine to relearn its idle, the idle quality of
your vehicle may be adversely affected until the idle is eventually
relearned.
²If the battery has been disconnected or a new battery has been
installed, the clock and the preset radio stations must be reset once
the battery is reconnected.
²Always dispose of automotive
batteries in a responsible manner.
Follow your community's
standards for disposal. Call your
local recycling center to find out
more about recycling automotive
batteries.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Changing the wiper blades
When replacing wiper blade assemblies, always use a Motorcraft part or
equivalent. To make replacing the wipers easy, turn the ignition to ACC,
then turn the wipers on. When the wipers reach the vertical position,
turn the ignition to LOCK.
Maintenance and care

²Be particularly careful if you are taking ªAntabuseº or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors
or skin contact could cause an adverse reaction. Consult a physician
immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Vehicles certified to California emission standards (indicated on the
underhood Vehicle Emissions Control Information label) are designed to
operate on California reformulated gasolines. If California reformulated
gasoline is not available when you refuel, your vehicle can be operated
on non-California fuels. However, even though your engine will perform
adequately on other gasolines, the performance of the emission control
devices and systems may be adversely affected.
Repair of damage caused by using a fuel that your vehicle was not
designed for may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªPremiumº gasoline for optimum
performance with an (R+M)/
2 octane rating of 91 or higher.
Gasolines with lower octance ratings
can be used, but performance may
decrease. We do not recommend
gasolines labeled as ªPremiumº in
high altitude areas that are sold with octane ratings less than 91.
Do not be concerned if your vehicle sometimes knocks lightly. However,
if it knocks heavily under most driving conditions on fuel with the
recommended octane, see your dealer or a qualified service technician to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº gasoline.
ªPremiumº gasoline is not recommended (particularly in the United
91(R+M)/2 METHOD
Maintenance and care

States) because it may cause these problems to become more
pronounced. If the problems persist, see your dealer or a qualified
service technician.
The American Automobile Manufacturers Association (AAMA) issued a
gasoline specification to provide information on high quality fuels that
optimize the performance of your vehicle. We recommend the use of
gasolines that meet the AAMA specification if they are available.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use a high-quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air quality, including
reformulated gasolines that contain oxygenates up to 10% ethanol or
15% MTBE.
Do not use gasolines containing methanol, which can damage critical fuel
system components. Damage resulting from the use of methanol may not
be covered by your warranty.
Running out of fuel
Avoid running out fuel because this situation may have an adverse affect
on modern powertrain components.
You may need to crank the engine several times before the system starts
to pump fuel from the tank to the engine. If you run out of fuel, your
Check Engine light may come on. For more information on the Check
Engine light, refer to theInstrumentationchapter.
Calculating fuel economy
To accurately calculate your vehicle's fuel economy:
1. Fill the tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five fuel tank fill-ups, fill the fuel tank and
record the current mileage reading.
4. Use one of the following equations to calculate fuel economy.
Liters used x 1004Total kilometers traveled
Total miles traveled4Total gallons used
