2018 FORD TRANSIT coolant temperature

The automatic regeneration process is
most effective when you drive at a steady
vehicle speed of 30 mph (48 km/h) or
above for approximately 20 minutes. The
frequency and duration of the regeneration
process varies by how you drive your
vehicle, the outside air temperature and
altitude. Frequency varies between 100 mi
(160 km)
and 310 mi (500 km) and each
regeneration process lasts between 10 and
20 minutes.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
Note: During regeneration at low speed or
engine idle, you could smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to the high temperatures
reached during the regeneration process.
This is normal.
Diesel Particulate Filter Manual
Regeneration
(If Equipped) WARNING:
Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will radiate
a considerable amount of heat during and
after regeneration and after you have
switched the engine off. This is a potential
fire hazard. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the diesel oxidation catalytic converter or the diesel particulate
filter. The diesel oxidation catalytic
converter and the diesel particulate filter
heat up to very high temperatures after
only a short period of engine operation and
remain hot after you switch the engine off.
Diesel particulate filter warning
lamp.
If the diesel particulate filter is
near or at saturation, the warning lamp
appears advising you to initiate diesel
particulate filter manual regeneration.
Before you start manual regeneration, do
the following:
• Park your vehicle outside of any
enclosed structure.
• Make sure the transmission is in park
(P) or neutral (N).
• Make sure the parking brake is on.
• Park your vehicle a minimum of
10 ft
(3 m) from any obstructions and
materials that can easily combust or
melt, for example, paper, leaves, fuels,
plastics and other dry organic material.
• Make sure there is a minimum of 3.2 gal
(12 L)
of fuel in the fuel tank.
• Check the engine oil level.
• Check the engine coolant level.
Manual Regeneration
Where vehicle use has significant engine
idle operation, frequent vehicle speed less
than
25 mph (40 km/h), or driving short
distances where the engine does not fully
warm up, manual regeneration allows you
to start diesel particulate filter cleaning
when the engine is idling.

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics. The engine
also needs to break in. Avoid hard
accelerations and driving too fast for the
first 1,000 mi (1,600 km). If possible, avoid
carrying heavy loads up steep grades
during the break-in period.
REDUCED ENGINE
PERFORMANCE WARNING:
If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See
Gauges
(page 93).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down. 4. Check the coolant level. See
Engine
Coolant Check (page 236).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
The following helps to improve fuel
consumption:
• Regularly check your tire pressures and
make sure that they are inflated to the
correct pressure.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Plan your journey and check the traffic
before you set off.
• Avoid idling the engine in cold weather
or for extended periods. Start the
engine only when you are ready to set
off.
• Do not carry unnecessary weight in your
vehicle as extra weight wastes fuel.
• Do not add unnecessary accessories
to the exterior of your vehicle, for
example running boards. If you use a
roof rack, remember to fold it down or
remove it when not in use.
• Drive smoothly, accelerate gently and
anticipate the road ahead to avoid
heavy braking.
• Switch off all electric systems when
not in use, for example air conditioning.
Make sure that you unplug any
accessories from the auxiliary power
points when not in use.

ENGINE COOLING FAN -
DIESEL WARNING: Keep your hands and
clothing clear of the engine cooling fan.
Under certain conditions, the engine
cooling fan may continue to run for several
minutes after you switch your vehicle off.
This could happen in low ambient
temperatures and independent of the
engine coolant temperature, for example
short journeys or low coolant temperature.
See Diesel Particulate Filter (page 145).
ENGINE COOLING FAN - E85/
GASOLINE WARNING:
Keep your hands and
clothing clear of the engine cooling fan.
Under certain conditions, the engine
cooling fan may continue to run for several
minutes after you switch your vehicle off. ENGINE COOLANT CHECK WARNING:
Do not remove the
coolant reservoir cap when the cooling
system is hot. Wait 10 minutes for the
cooling system to cool down. Cover the
coolant reservoir cap with a thick cloth to
prevent the possibility of scalding and
slowly remove the cap. Failure to follow
this instruction could result in personal
injury. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING:
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 you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 459).
Note: Make sure that the coolant 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.

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 305).
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 WARNING:
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. WARNING:
Do not remove the
coolant reservoir cap when the cooling
system is hot. Wait 10 minutes for the
cooling system to cool down. Cover the
coolant reservoir cap with a thick cloth to
prevent the possibility of scalding and
slowly remove the cap. Failure to follow
this instruction could result in personal
injury.
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 stop your vehicle. You can
continue to drive. 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. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
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 459). 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.
