VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.
WARNING: Exercise great caution
when working on a vehicle equipped with
an automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature
or the refrigerant pressure (if equipped
with air conditioning) reaches a
predetermined setting. The fan starts at
this point with no advance warning.
Never reach near, or permit objects to
protrude into, the fan blade radius while
the engine is running as this could result
in vehicle damage, personal injury or
death.
WARNING: Do not operate the
vehicle if any suspension conditions
listed in the following charts are evident.
Loss of steering or suspension could
result in property damage, personal injury
or death.
WARNING: If a wheel must be
changed, obtain expert tire service help.
Mounting and un-mounting of tires
should only be performed by a qualified
technician using necessary safety
procedures and equipment, otherwise
the result could be property damage,
personal injury or death.
Note:Always make sure you apply the
parking brake before starting the engine.
Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See Engine Oil Dipstick (page 224). Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See Engine
Coolant Check (page 238). Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check (page 245). Power steering fluid

Maintenance

•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.
• The first step is once the coolant
concentration is verified to be in the
range of 40 – 60%. Test the
corrosion inhibitor additive
strength. If the test results show
the cooling system does not have
excessive contamination and the
corrosion inhibitor additive strength
is sufficient then no further action
is required. If the test results for the
Engine Coolant Circuit show the
cooling system has excessive
contamination or the corrosion
inhibitor additive strength is not
sufficient then add 47 fl oz (1.4 L)
of Motorcraft Specialty Orange
Engine Coolant Revitalizer. If the
test results for the Secondary
Coolant Circuit show the cooling
system has excessive
contamination or the corrosion
inhibitor additive strength is not
sufficient then 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 288).
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 288).
Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle may have 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.
237
Maintenance

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 engine
coolant for optimum cooling system and
engine protection.
Coolant Change
Change the coolant at specific mileage
intervals as listed in the scheduled
maintenance information. 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 288).
