Maintenance
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. Remove the filler cap.
2. Add engine oil that meets the Fordspecifications. See Capacities
and Specifications (page 329).
3. Replace the filler cap. Turn it until you feel a strong resistance.

ENGINE COOLANT CHECK
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
436).
Note: Make sure that the 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.
The coolant concentration should be
maintained within 48% to 50%,
which equates to a freeze point
between -30°F degrees (-34ºC) and
-34ºF (-37ºC).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your
authorized dealer. Ford does 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 or antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
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, you can be burned if you spill
coolant on hot engine parts.
272
Maintenance
WARNINGS
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 the cap is loosened slightly.
Do not add coolant further than
the MAX mark.
Note: Do not use stop leak pellets,
cooling system sealants, or additives
as they can cause damage to the
engine cooling or heating systems. This
damage would not be covered under
your vehicle’s warranty.
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 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. Make
sure the correct coolant is used.
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 Scheduled
Maintenance (page 436).
• In case of emergency, a large amount of water without engine
coolant may be added in order to
reach a vehicle service location. In
this instance, the cooling system
must be drained, chemically
cleaned with Motorcraft®
Premium Cooling System Flush,
and refilled with engine coolant as
soon as possible. Water alone
(without engine coolant) can
cause engine damage from
corrosion, overheating or freezing.
• Do not use alcohol, methanol, brine or any engine coolants mixed
with alcohol or methanol
antifreeze (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.
Unscrew the cap slowly. Any pressure
will escape as you unscrew the cap.
Add prediluted engine coolant
meeting the Ford specification. See
Scheduled Maintenance (page 436).
273
Maintenance
Whenever coolant has been added,
the coolant level in the coolant
reservoir should be checked the next
few times you drive the vehicle. 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 Fordauthorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant
concentrations above 60% will
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% will provide improved overheat
protection. Engine coolant
concentrations below 40% will
decrease the corrosion/freeze
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 the engine coolant supply is
depleted, this feature allows the
vehicle to be driven temporarily before
incremental component damage is
incurred. 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:
A high engine temperature
message will appear in the
information display.
The service engine soon
indicator will illuminate.
274
Maintenance
If the engine reaches a preset
over-temperature condition, the
engine will automatically switch to
alternating cylinder operation. Each
disabled cylinder acts as an air pump
and cools the engine.
When this occurs, the vehicle will still
operate. However:
• The engine power will be limited.
• The air conditioning system will bedisabled.
Continued operation will increase the
engine temperature and the engine
will completely shut down, causing
steering and braking effort to increase.
Once the engine temperature cools,
the engine can be re-started. 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 the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to
rest in a safe location and seek
immediate repairs. When in fail-safe
mode, the 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.
WARNINGS
Never remove the coolant
reservoir cap while the engine is
running or hot.
You have limited engine power when
in the fail-safe mode, so drive the
vehicle with caution. The vehicle will
not be able to maintain high-speed
operation and the engine will run
rough. Remember that the engine is
capable of completely shutting down
automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without
repairing the engine problem increases
the chance of engine damage. Take
your vehicle to an authorized dealer as
soon as possible.

Capacities and Specifications
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and,
by itself, does not necessarily indicate
a concern or that the fluid needs to be
changed. However, a qualified expert,
such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also
show signs of overheating or foreign
material contamination immediately.Make sure to change your vehicle’s
oils and fluids at the specified
intervals or in conjunction with a
repair. Flushing is a viable way to
change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems
are flushed only with new fluid that is
the same as that required to fill and
operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Make sure you perform the following
basic maintenance checks and
inspections every month or at
six-month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
