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 400).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
(-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.
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.
212
Maintenance
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 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 261).
• 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.
• 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 261).
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.
213
Maintenance
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% 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 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.
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.
214
Maintenance
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.
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 400). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
(i.e., if the transmission slips or shifts
slowly) 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.
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.
215
Maintenance
When a low voltage battery replacement
is necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle
To ensure proper operation of the battery
management system (BMS), do not allow
a technician to connect any electrical
device ground connection directly to the
low voltage battery negative post. A
connection at the low voltage battery
negative post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note:If a person adds electrical or
electronic accessories or components to the
vehicle, the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle.
Because your vehicle’s engine is
electronically-controlled by a computer,
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 stationpresets, 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. Complete the following procedure
in order to restore the settings:
1. With the vehicle at a complete stop,
set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the
vehicle.
5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 267). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 78).
Reset the radio station presets. See
Audio System (page 267).
6. Allow the engine to idle for at least one
minute. If the engine turns off, step on
the accelerator to start the engine.
7. While the engine is running, step on the
brake pedal and shift the transmission
to N.
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 10 miles (16
kilometers) to completely relearn the
idle and fuel trim strategy.
Note:If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
217
Maintenance
5. Install in the reverse order.
Note:Make sure that the wiper blade locks
into place.
Replace wiper blades at least once per
year for optimum performance.
Poor wiper quality can be improved by
cleaning the wiper blades and the
windshield.
CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running.
When changing the air filter element, use
only the air filter element listed. See
Capacities and Specifications (page
261).
For EcoBoost equipped vehicles: When
servicing the air cleaner, it is important that
no foreign material enter the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.
Change the air filter element at the proper
interval. See Scheduled Maintenance
(page 400).
Note:Failure to use the correct air filter
element may result in severe engine
damage. The customer warranty may be
void for any damage to the engine if the
correct air filter element is not used.
