ENGINE COOLANT CHECK -
2.0L ECOBOOST™/3.7L
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
440
).
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 (-34 C) and
-34 F (-37 C).
268
Maintenance

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. 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 Capacities and
Specifications (page 325).
• 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 prediluted engine
coolant as soon as possible. Water
alone (without engine coolant)
can cause engine damage from
corrosion, overheating or freezing.
269
Maintenance

•
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
Capacities and Specifications
(page 325).
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.
Always dispose of used automotive
fluids in a responsible 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%
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.

Maintenance

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: 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 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 be
disabled.
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. 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.
271
Maintenance

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.
AUTOMATIC
TRANSMISSION FLUID
CHECK
Note: Transmission fluid should be
checked by an authorized dealer. If
required, fluid should be added by an
authorized dealer.
The automatic transmission does not
have a transmission fluid dipstick.
Have an authorized dealer check and
change the transmission fluid and
filter at the correct service interval.
See Scheduled Maintenance (page
440). Your transmission does not
consume fluid. However, the fluid level
should be checked if the transmission
is not working properly, or if you notice
some sign of fluid leakage.
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. 6F35/HF35 transmission

Maintenance

Note:
Automatic transmission fluid
expands when warmed. To obtain an
accurate fluid check, drive the vehicle
until it is warmed up (approximately
20 miles [30 kilometers]). If your
vehicle has been operated for an
extended period at high speeds, in city
traffic during hot weather or pulling a
trailer, the vehicle should be turned off
until normal operating temperatures
are reached to allow the fluid to cool
before checking. Depending on vehicle
use, cooling times could take up to 30
minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals
for fluid checks and changes. Your
transmission does not consume fluid.
However, the fluid level should be
checked if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or
if you notice some sign of fluid
leakage.
1. Drive the vehicle 20 miles (30 kilometers) or until it reaches
normal operating temperature

Checking the fluid level
Low fluid level
If the fluid level is below the MIN range
of the dipstick, add fluid to reach the
hash mark level.
Note:
If the fluid level is below the MIN
level, do not drive the vehicle. An
underfill condition may cause shift or
engagement concerns or possible
damage.
Correct fluid level The transmission fluid should be
checked at normal operating
temperature 180°F-200°F
(82°C-93°C) on a level surface. The
normal operating temperature can be
reached after approximately 20 miles
(30 kilometers) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C). High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.
Note:
Fluid level above the MAX level
may cause shift or engagement
concerns or possible damage. High
fluid levels can be caused by an
overheating condition. If your vehicle
has been operated for an extended
period at high speeds, in city traffic
during hot weather or pulling a trailer,
the vehicle should be turned off until
normal operating temperatures are
reached. Depending on vehicle use,
cooling times could take up to 30
minutes or longer.

Before adding any fluid, make sure the
correct type is used. The type of fluid
used is normally indicated on the
dipstick and also in the Technical
Specifications section in this chapter.
Note:
An overfill condition of
transmission fluid may cause shift or
engagement concerns or possible
damage.
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. Reinstall
the air filter assembly. After the fluid
level has been checked and adjusted
as necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.

BRAKE 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.

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 325).
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common
windshield washer antifreeze additive.
Washer fluids containing
non-methanol antifreeze agents
should be used only if they provide
cold weather protection without
damaging the vehicle ’s paint finish,
wiper blades or washer system. CHANGING THE 12V
BATTERY WARNINGS
Batteries normally produce
explosive gases which can cause
personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery,
always shield your face and protect
