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 engine
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. The
information display may display a message
to change coolant at this time. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 252). Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle is equipped with an engine
driven cooling fan drive (also called a fan
clutch). This fan drive changes the fan
speed to match the vehicle
’s changing
cooling air flow requirements. Fan speed,
fan noise level and fuel consumption all
will increase based on the driving
conditions that include trailer towing, hill
climbing, heavy loads, high speed and high
ambient temperature, individually or in
combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time.
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.

Robinair® Coolant and Battery
Refractometer 75240 –
Recommended refractometer to test
coolant concentration. (Rotunda tool
part number: ROB75240).
• Rotunda 328-R071–ELC (Antifreeze
Coolant ELC Contamination Kit)
–
Evaluates the corrosion inhibitor
additive strength. Note the first step is
to verify the vehicle ’s coolant
concentration is in the correct range of
40 – 60%. Coolant concentrations
outside this range will not provide valid
test results. If the report results in a
pass, for example the cooling system
does not show excessive
contamination, the corrosion inhibitor
additive strength is sufficient, and no
action is required. If the report results
as insufficient (does not pass), the
corrosion inhibitor additive strength of
the coolant is too low. If the engine
cooling system corrosion inhibitor
additive strength is low, add
47 fl oz
(1.4 L) of Motorcraft Specialty Orange
Engine Coolant Revitalizer. If the
secondary cooling system corrosion
inhibitor additive strength is low, add
16 fl oz (0.47 L) of Motorcraft Specialty
Orange Engine Coolant Revitalizer.
• Motorcraft Specialty Orange Engine
Coolant Revitalizer
– Additive to
boost the corrosion inhibitor level
based upon the test results of the
Antifreeze Coolant ELC Contamination
Kit. The Revitalizer may be added two
times over the life of the coolant. If
additional dosages are required, the
cooling system must be flushed and
refilled per the instructions in the
Workshop Manual.
Make sure to follow the proper coolant and
additive specifications. See
Capacities
and Specifications (page 252). Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
information display may display a message

AUTOMATIC TRANSMISSION
FLUID CHECK
The 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, shifts
slowly or if there are signs of fluid loss.

the owner when installing replacement
parts to be sure that a tampering act (as
outlined above) is not committed. Note
any inspection and service performed in
the maintenance log.
Emissions Information Label
Emissions information appears on the
Important Engine Information decal
located on or near the engine.
