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 capacityTo find out how much fluid your vehicle's cooling
system can hold, refer to theCapacities and
Specificationschapter.
Have your dealer check the engine cooling system
for leaks if you have to add more than a quart
(liter) of engine coolant per month.Severe winter climateIf you drive in extremely cold climates (less than
-34ÊF[-36ÊC]), it may benecessary 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. Neverincrease 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.
Proper procedures for a complete coolant drain and
flush of the cooling system can be found in theCar
Service Manual.Following these recommended
procedures will ensure that the specified coolant
level and a 50/50 or appropriate mixture of coolant
and water is maintained.
Engine Coolant Refill ProcedureWhen the entire cooling system is drained and
refilled, the following procedure should be used to
ensure a complete fill:
NOTE:It is imperative the following procedure be
adhered to. Failure to do so could result in damage
to your engine.

With the engine OFF and cool, remove the
pressure cap, located on the coolant reservoir.
Remove the heater hose and clamp, located on
the rear of the intake manifold.
q
Add a 50/50 mixture of specified coolant and
water to the coolant reservoir. Refer toRefill
Capacitieslater in this chapter for the correct
amount. Add coolant to the reservoir until the
coolant continuously flows out of the tube in
the rear of engine. Reattach hose and secure
clamp.
q
Reinstall the pressure cap to the fully installed
position.
q
Start and idle the engine until the radiator
upper hose is warm (this indicates the
thermostat is open and coolant is flowing
through the entire system).
q
Immediately shut off the engine and let cool.
Cautiously remove the pressure relief cap and
add a 50/50 mixture of specified coolant and
water until the coolant is at the COLD FILL
level in the coolant reservoir.
q
Reinstall the pressure cap securely.
q
Check for leaks at the draincock.
q
Recheck the engine coolant level, using the
recommended procedure, after one or two
occasions of vehicle use.

Power Steering FluidCheck the level of the power steering fluid at least
twice a year (i.e., every Spring and Fall).Checking and Adding Power Steering
Fluid1. Start the engine and let it run until the power
steering fluid reaches normal operating
temperature. The power steering fluid will be at
the right temperature when the engine coolant
temperature gauge in the instrument cluster is
near the center of the NORMAL operating
temperature range.
2. While the engine idles, turn the steering wheel
back and forth several times. Make sure that
the cap assembly is installed at this time.
3. Turn the engine off and check the level on the
power steering reservoir.4. The fluid level is viewed through the sight
window on the power steering reservoir. If the
power steering fluid is below the middle line,
add fluid in small amounts, continuously
checking the level. Do not overfill.
Fluid level for power steering
Use only MERCONHATF power steering fluid.

230If the power steering fluid is low, do not drive your
vehicle for a long period of time before adding fluid.
This can damage the power steering pump.Automatic Transmission FluidUnder 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 Schedulebooklet 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.
It is preferable to check the transmission fluid level
at normal operating temperature150ÊF-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).NOTE:If the vehicle has been operated for an
extended period at high speeds or 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.
Checking the Automatic Transmission
FluidWith the vehicle on a level surface and the brake
fully applied, start the engine and move the gear
shift selector through all of the gears allowing
sufficient time for each position to engage. Securely
latch the gear shift selector in the P (Park) position.
Fully set the parking brake and leave the engine
running.
NOTE:Your vehicle should not be driven if the
fluid level is below the bottom hole on the dipstick
and outside temperatures are above50ÊF(10ÊC).
Wipe off the dipstick cap and pull the dipstick out.
Wipe the indicator end clean. Put the dipstick back
into the filler tube and make sure it is fully seated.

232BatteryYour vehicle may have a Motorcraft
maintenance-free battery. When the original
equipment battery is replaced under warranty it
may be replaced by a low-maintenance battery. See
Motorcraft Partsat the end of this chapter for the
proper replacement battery.
The low-maintenance battery has removable vent
caps for checking the electrolyte level and adding
water. The electrolyte level should be checked at
least every 24 months or 24,000 miles
(40,000 km) in temperatures up to90ÊF(32ÊC)
and more often in temperatures above90ÊF(32ÊC).
Keep the electrolyte level in each cell up to the
level indicator. Do not overfill.
If the level gets low, refill the battery with distilled
water. If necessary, you can add tap water to the
battery, provided the water is not hard or does not
have a high mineral or alkali content. If the battery
needs water quite often, have the charging system
checked for a possible malfunction.
Help Us Protect Our EnvironmentFord Motor Company strongly recommends that
used lead-acid batteries be returned to an
authorized recycling facility for disposal.
Battery recycling symbolBecause 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.
If you do not let the engine relearn its idle, the idle
quality of your vehicle may be adversely affected
until the idle is relearned. Your vehicle will
eventually relearn its idle while you drive it, but it
takes much longer than if you use the previous
procedure.Wiper BladesCheck 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.
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.
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 replacementIf 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.

242Typical octane rating labelDo not be concerned if your vehicle sometimes
knocks lightly. However, if it knocks heavily under
most driving conditions on the recommended
octane fuel, see your dealer or a qualified service
technician to prevent any engine damage.Fuel qualityIf you are experiencing starting, rough idle or
hesitation problems try a different brand of fuel. If
the condition persists, 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 AirFord approves the use of gasolines to improve air
quality, including reformulated gasolines that contain
oxygenates such as a maximum of 10% ethanol or
15% MTBE. There should be no more than 5%
methanol with cosolvents and additives to protect
the fuel system.
