Washer fluid in the liftgate
reservoir
Washer fluid for liftgate wiper and
washer operation is supplied by
the washer fluid reservoir located
in the engine compartment. For
information on adding fluid to this
main reservoir, refer toWasher
fluid in the windshield reservoir
in this chapter.
CHECKING AND ADDING
ENGINE COOLANT
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 Ð 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.
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 to the
first stop.
3. Step back while the pressure
releases.
4. When you are sure that all the
pressure has been released, use
the cloth to press the cap down,
turn it counterclockwise and
remove it.
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 4 years or
80,000 km(50,000 miles).
Maintenance and care
166

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 the 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 the
Capacities and specifications
chapter.
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.

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.

What you should know about
fail-safe cooling
Vehicles equipped with 4.6L, and
5.4L engines have a fail-safe
cooling mode. If the engine coolant
supply is depleted, this feature
allows the vehicle to be driven
temporarily before incremental
component damage is incurred.
The ªfail safeº distance depends on
ambient temperatures, vehicle load
and terrain.
When fail-safe mode is
activated
²Pull off the road as soon as
possible.
²Immediately turn the engine off
to prevent severe engine
damage.
²Wait for the engine to cool.
²Check the coolant level.

How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The service engine soon light will
illuminate, indicating that vehicle
service is required.
The vehicle will still operate, but
will have limited engine power and
no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
CHECKING AND ADDING
POWER STEERING FLUID
Check the power steering fluid
level at least twice a year.
1. Start the engine.

2. When the engine coolant
temperature gauge reaches the
normal zone, turn the engine off.
3. Visually inspect the fluid level in
the power steering fluid reservoir.
4. Add power steering fluid until
the fluid level reaches MAX.
Use only fluid that meets Ford
specifications. Refer toCapacities

CHECKING AND ADDING
TRANSMISSION FLUID
Checking and adding automatic
transmission fluid (if equipped)
Service the automatic transmission
according to the scheduled
intervals in the9Service Guide.9
Before adding any fluid, make sure
the correct type will be used. This
information is indicated on the
dipstick.
²4R7OW automatic transmissions
are used with 4.6 L engine
applications.
²E4OD automatic transmissions
are used with 5.4 L engine
applications.
Do not drive the vehicle if the fluid
level is below the bottom hole on
the blade type dipstick (4R70W
transmission) or below the COLD
area on the bullet type dipstick
(E4OD transmission) and outside
temperatures are above 10ÉC
(50ÉF).
Your vehicle does not use up
transmission fluid. However, it is
recommended that you check the
transmission fluid at least twice a
year. The fluid level should be
checked if the transmission is not
working properly, i.e., if the
transmission slips or shifts slowly
or if you notice some sign of fluid
leakage.
It is preferable to check the
transmission fluid level at normal
operating temperature, afterexd_checking_adding_autotrans
