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
Capacities and Specifications (page
285).

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.

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.

Maintenance

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 285).

•

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 Capacities and
Specifications (page 285).

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 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.

240

Maintenance

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.

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.

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.

Maintenance

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 426). 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 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.

FUEL FILTER

Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

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.

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 285).

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 your eyes. Always provide proper
ventilation.
