Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
Fan clutches
Your vehicle’s cooling system is equipped with a viscous fan clutch
which:
•Helps control cooling, increase performance, improve fuel economy
and reduce noise.
•Is controlled by bimetallic spring sensors. Do not tamper with these
sensors as this may change their calibration or keep the fan clutch
from operating at all.
WARNING:Stay clear of the fan/fan area while the engine is
running or possible personal injury may occur.
ENGINE COOLANT (GAS ENGINE ONLY)
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed in your scheduled maintenance information. The coolant
concentration should be maintained at 50/50 coolant and distilled water.
For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentration. The level of coolant should
be maintained at the FULL COLD level or within the COLD FILL RANGE
in the coolant reservoir. If the level falls below, add coolant per the
instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Improved freeze protection.
•Improved boiling protection.
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
When the engine is cold, check the level of the engine coolant in the
reservoir.

Among those acts presumed to constitute tampering are the following
acts listed:
Vehicle system Acts
Acoustical shielding Removal of noise shields, hood blanket, tunnel
liner or acoustical absorptive material.
Engine Removal or rendering inoperative the engine
speed governor so as to allow engine speed to
exceed manufacturer specifications. Removal of
engine mounted noise shield or oil pan enclosure.
Engine air induction Removal of the air duct, silencer, air cleaner,
and/or air cleaner element and baffle in air
cleaner; re-indexing of air cleaner.
Exhaust Removal or rendering inoperative exhaust system
components including the catalytic converter -
muffler assembly, inlet pipe, outlet pipe,
resonator and flexpipe. Rotation of horizontal
exhaust system directional outlet pipe to cause
the exhaust to be emitted in a direction other
than the orientation the vehicle was originally
produced with.
Engine cooling Removal or rendering inoperative the fan clutch.
Removal or modification of the fan shroud.
Replacing a fixed fan with a fan of increased
diameter, different number of blades or different
pitch width.
DEF (Diesel
exhaust fluid)Removal or rendering inoperative DEF system
components including the DEF tank, dosing
module, dosing supply module, dosing control
unit, NOx electronic module or NOx sensor.
Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
