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
f12_refill_capacity
f12_winter_climate
Maintenance and care
169

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 the cooling system
hoses
Inspect all engine and heater
system hoses and hose connections
for:
²deterioration
²leaks
²loose hose clamps
What you should know about
fail-safe cooling (if equipped)
Vehicles equipped with 4.6L or
5.4L engines have a fail-safe
com_checking_hoses.01
f12_wysk_failsafe_cooling
Maintenance and care
170

cooling mode. If the engine coolant
supply is depleted, this feature
allows the driver to drive the
vehicle (with limited power) for a
short distance in order to get the
vehicle to a service facility. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
The actual distance your vehicle
can be driven depends on vehicle
load, road conditions and outside
temperature.
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
CHECK
ENGINElight 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.
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.
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
and specifications.

1. Park the vehicle on a level
surface.
2. 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), set the parking brake and
leave the engine running.
4. Remove the dipstick, wiping it
clean with a clean, dry rag.
5. Install the dipstick.
6. Remove the dipstick and inspect
the fluid level.
²For 4R70W transmissions, the
fluid level should be within the
crosshatched area, or if the
vehicle has not been driven,

have the charging system checked
for a possible malfunction.
Your vehicle is equipped with a
battery saver feature designed to
prevent your battery from
accidental wear down due to doors
left ajar. For information on this
system, refer to theControls and
featureschapter.
Relearning idle conditions
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 computer must
ªrelearnº its idle conditions before
your vehicle will drive properly. To
complete this process:
1. Put the gearshift in P
(Park)(automatic transmission) or
N (Neutral)(manual transmission).
2. Turn off all accessories, and
start the engine.
3. Let the engine idle for at least
one minute.
4.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
Maintenance and care
180

preset radio stations must be
reset once the battery is
reconnected.
²Always dispose of used
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.
CHANGING THE AIR FILTER
1. Loosen the clamp that secures
the air cleaner in place.
2. Separate the two halves of the
air cleaner.
3. Remove the air filter element
from the open end of the engine
air cleaner and replace it with a
new element. Be careful not to
crimp the filter edges between
halves. This could cause filter
damage if not properly seated.
4. Replace the two halves of the
air cleaner and secure the clamp.
For information on replacement air
filter elements, refer to the
Capacities and specifications
chapter.
REPLACING THE WIPER
BLADES
If the windshield wiper blades do
not work properly after cleaning,
replacement of the blade element
may be necessary.
