Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile
manufacturers.
1. Check the engine oil level.
2. If the engine oil level is not within the
normal range, add engine oil that
meets Ford specifications. See
Capacities and Specifications (page
267
).
3. Remove the engine oil filler cap and use a funnel to pour the engine oil into
the opening.
4. Recheck the engine oil level. Make sure
the oil level is not above the normal
operating range on the engine oil level
dipstick.
5. Install the engine oil level dipstick and ensure it is fully seated.
6. Fully install the engine oil filler cap by turning the filler cap clockwise until
three clicks are heard or until the cap
is fully seated.
ENGINE COOLANT CHECK WARNINGS
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. WARNINGS
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 414).
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.
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, this color change does
not indicate that the engine coolant has
degraded, nor does it require that qualified
personnel drain the engine coolant, flush
the system or replace the engine coolant.
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 267).
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.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol. •
Brine.
• Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
2. Add prediluted engine coolant meeting
the Ford specification. See
Capacities
and Specifications (page 267).
3. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
4. If necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed
of in an appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to have a Ford
authorized dealer increase the coolant
concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Engine coolant
concentrations above 60% decrease
the overheat protection characteristics
of the engine coolant and may cause
engine damage.
If you drive in extremely hot climates:
• It may be necessary to have a Ford
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
Engine coolant concentrations below
40% will decrease the freeze and
corrosion protection characteristics of
the engine coolant and may cause
engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
What You Should Know About Fail-
Safe Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to
the red (hot) area and: the coolant temperature
warning light will illuminate the service engine soon indicator
will illuminate.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle will still
operate. However:
• The engine power will be limited.
• This will disable the air conditioning
system.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start your engine. Take your vehicle
to an authorized dealer as soon as possible
to minimize engine damage.
When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long
as necessary to bring your vehicle to rest
in a safe location and seek immediate
repairs. When in fail-safe mode, your
vehicle will have limited power, will not be
able to maintain high-speed operation, and
may completely shut down without
warning, potentially losing engine power,
power steering assist, and power brake
assist, which may increase the possibility
of a crash resulting in serious injury. Never remove the coolant reservoir
cap while the engine is running or hot.

5. If the coolant is low, add coolant, and
restart the engine. See Adding Engine
Coolant or How Fail-Safe Cooling
Works in this chapter for more
information.
MANUAL TRANSMISSION
FLUID CHECK
1. Clean the filler plug. It is located on the
passenger side of the transmission. 2. Remove the filler plug and inspect the
fluid level.
3. For vehicles with a the I4 or V6 engine,
the correct manual transmission fill
level is at the lower edge of the filler
hole. For vehicles equipped with a V8
engine, the correct manual
transmission fill level is 1/2 inch (1.3
cm) below the edge of the filler hole.
4. Add enough fluid through the filler opening to bring the fluid up to the
recommended levels.
5. Install and tighten the fill plug securely.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 267). AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See
Scheduled
Maintenance (page 414).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
BRAKE AND CLUTCH FLUID
CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating range;
there is no need to add fluid. If the fluid
levels are outside of the normal operating
range, the performance of the system
could be compromised; seek service from
your authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
