Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling system
can burn you badly. Also, spilling coolant on
hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine coolant
could make it difficult to see through the
windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure relief cap.
The cooling system is under pressure. Steam
and hot liquid can come out forcefully when
you loosen the cap slightly. Do not add coolant further than the
MAX mark.

Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine coolant
at the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 499).
Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Note: For best results, coolant concentration
should be tested with a refractometer such
as Robinair® Coolant and Battery
Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations. Note:
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
Note: Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. Your warranty may not
cover these damages.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red. As long as the
engine coolant is clear and uncontaminated,
any color change does not indicate the
engine coolant has degraded, nor does it
require the engine coolant to be drained,
the system to be flushed, or the engine
coolant to be replaced. Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine
’s cooling
system. The use of an improper coolant may
harm engine and cooling system
components and may void the warranty. Use
prediluted engine coolant meeting the Ford
specification.
See Capacities and
Specifications (page 370).
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system with
Motorcraft Premium Cooling System
Flush.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

High Fluid Level
If the fluid level is above the maximum range
(above point A) fluid may need to be
removed. High fluid levels may be caused
by a overheating condition. If you have
operated your vehicle at high speeds, towing
a trailer or in city traffic during hot weather,
allow your vehicle to cool for a minimum of
30 minutes before rechecking the level.
Note:
An overfill conition can damage the
transmission.
Adding Transmission Fluid *
1. Rotate the automatic transmission fluid cap in a counterclockwise direction. *
2. Remove the cap and dipstick and wipe it with a clean, lint-free cloth.
3. Add fluid that meets the Ford specifications. See Capacities and
Specifications (page 376). Pour the fluid
directly into the automatic transmission
fluid cap and dipstick hole.
4. Replace the cap and dipstick and remove
it again to check the fluid level. 5.
Make sure that the fluid level is between
the MIN and the MAX marks.
6. Replace the automatic transmission fluid
cap and dipstick. Turn it clockwise until
you feel a strong resistance.

Transmission Fluid Level.
5. Install in reverse order. Tighten the two air filter assembly securing bolts until you
feel a strong resistance.
BRAKE FLUID CHECK WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of incorrect fluid
could result in the loss of vehicle control,
serious personal injury or death. Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other materials
may result in brake system damage or failure.
Failure to adhere to this warning could result
in the loss of vehicle control, serious
personal injury or death. Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with plenty of
water and contact your physician. WARNINGS
A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need to add
fluid. A fluid level not in the normal operating
range could compromise the performance
of the system. Have your vehicle checked
immediately. Only use fluid that meets Ford specifications.See
Capacities and Specifications (page
370).
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase the
risk of injury or accident. Note:
The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets Ford
specifications.
See Capacities and
Specifications (page 370).

some engine control settings are maintained
by power from the low voltage battery. Some
engine computer settings, like the idle trim
and fuel trim strategy, optimize the
driveability and performance of the engine. Some other computer settings, like the clock
and radio station presets, are also maintained
in memory by power from the low voltage
battery. When a technician disconnects and
connects the low voltage battery, these
settings are erased.
Note:
Until you switch the ignition to the on
position, you will receive a message in your
information display stating that your vehicle
is not in park.
