Ford Transit Connect (2018 year). Manual — part 50

If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

To top up the coolant level do the
following:

1.

Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.

2. Add prediluted coolant approved to

the correct specification. See
Capacities and Specifications (page
255).

3. Add enough prediluted coolant to

reach the correct level.

4. Replace the coolant reservoir cap, turn

it clockwise until you feel a strong
resistance.

5. Check the coolant level in the coolant

reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.

Note: During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.

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 coolant mixed with alcohol or
methanol antifreeze.

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 coolant.

Recycled Coolant

We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.

Dispose of used engine coolant 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 increase the
coolant concentration above 50%.

•

A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.

If you drive in extremely hot climates:
•

You can decrease the coolant
concentration to 40%.

•

Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the
coolant and may cause engine
damage.

Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.

Coolant Change

At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 255).

Fail-Safe Cooling

Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.

How Fail-Safe Cooling Works

If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:

A warning lamp illuminates and
a message may appear in the
information display.

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 still
operates, however:
•

Engine power is limited.

•

The air conditioning system turns off.

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 the engine. Have your vehicle
checked 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 when the engine is running or
hot.

Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:

1.

Pull off the road as soon as safely
possible and switch the engine off.

2. If you are a member of a roadside

assistance program, we recommend
that you contact your roadside
assistance service provider.

3. If this is not possible, wait a short

period for the engine to cool.

4. Check the coolant level. If the coolant

level is at or below the minimum mark,
add prediluted coolant immediately.

5. When the engine temperature cools,

you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.

Note: Driving your vehicle without repair
increases the chance of engine damage.

Engine Coolant Temperature
Management

(If Equipped)

WARNING

To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not

be able to accelerate with full power until
the coolant temperature reduces.

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.

At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to
drive your vehicle.

The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.

If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:

1.

Pull off the road as soon as safely
possible and shift the transmission into
park (P).

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant
immediately.

5. If the coolant level is normal, restart

the engine and continue.

AUTOMATIC TRANSMISSION
FLUID CHECK

The automatic transmission does not have
a transmission fluid dipstick.

Have an authorized dealer check and
change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 388). 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 FLUID CHECK

WARNINGS

Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of

incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other

materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.

Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with

plenty of water and contact your physician.

WARNINGS

A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need

to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately.

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.

Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 255).

WASHER FLUID CHECK

Note: The reservoir supplies the front and
rear washer systems.

When adding fluid, use a mixture of washer
fluid and water to help prevent freezing in
cold weather and improve the cleaning
capability. We recommend that you use
only high quality washer fluid.

For information on fluid dilution, refer to
the product instructions.

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 correct
ventilation.
