Engine cooling system
The cooling system contains an engine oil cooler which is mounted in the
center valley of the engine. The cooler’s function is to regulate engine oil
temperature.
Engine governed speed
The engine governor is controlled by the PCM. The PCM controls fuel
input to limit maximum engine speed. It will not, however, prevent
engine overspeeding resulting from downshifting at high vehicle speed or
by descending steep grades at too high a vehicle speed for the selected
transmission gear.
On F-Super Duty vehicles equipped with a manual transmission,
refer toManual transmission shift speedsin theDrivingchapter of
yourOwner’s Guidefor maximum vehicle speed in various gears. Do not
exceed 3,600 rpm. Maximum engine governed speed is 4,000 rpm
depending on engine load. Excessive rpm can only be achieved by
manually downshifting at too high of a vehicle speed.
Operating the engine beyond the governed speed can cause
severe engine damage.

If engine cranks but won’t start
Prolonged starter cranking (in excess of 30 seconds) could cause
damage to the starter motor.
•Check the fuel gauge. You may be out of fuel. If the gauge shows that
there is fuel in the tank, the trouble may be in the electrical system or
the fuel system. If equipped with an auxiliary tank, be sure that the tankcontrol switch is set for the tank with fuel and not on an empty tank.
•Leaving the ignition key turned to 4 (ON) for over two minutes
without starting may make starting difficult because the glow plugs
will cease activation. Reset the system by turning the ignition key to 3
(OFF) and then back to 4 (ON) again.
If the engine runs hot
The following could cause the engine to overheat:
•Lack of coolant.
•Dirty cooling system.
•Plugged radiator fins, charge air cooler, A/C condenser and/or oil
cooler.
•Driving with frozen coolant.
•Sticking thermostat.
•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air cleaner element.
If fuses burn out
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Replacement fuses and circuit breakers must always be the same
rating as the original equipment shown. Never replace a fuse or
circuit breaker with one of a higher rating. Higher rated fuses or circuit
breakers could allow circuit overloading in the event of a circuit malfunction,
resulting in severe vehicle damage or personal injury due to fire.
Refer to theOwner’s Guidefor replacement of fuses.

Multi-point Inspection
In order to keep your vehicle running right, it is important that you have
the systems on your vehicle checked regularly. This can help identify any
potential issue before there are any problems. Ford Motor Company
suggests the following multi-point inspection to be performed at every
scheduled maintenance as the way to ensure your vehicle keeps running
right.
Check every month
❑Check function of all interior and exterior lights❑Check tires for wear and adjust air pressure (including spare tire)
❑Check engine oil level
❑Check windshield washer fluid level
❑Check and drain fuel filter/water separator
Check every six months
❑Check lap/shoulder belts and seat latches for wear and function❑Check that externally-mounted spare tire is tight (seeOwner’s Guide)
❑Check power steering fluid level
❑Check washer spray, wiper operation and clean all wiper blades (replace as necessary)
❑Check parking brake for proper operation
❑Check and lubricate all hinges, latches and outside locks
❑Check and lubricate door rubber weatherstrips
❑Check and clean body and door drain holes
❑Check safety warning lamps (brake, ABS, air bag, safety belt) for operation
❑Check cooling system fluid level and coolant strength
❑Check battery connections and clean if necessary
❑Check clutch fluid level, if equipped
Retightening lug nuts
❑On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque at 500 miles (800 km) after
any wheel disturbance (tire rotation, changing a flat tire, wheel removal, etc.).
❑On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified torque at 100 miles (160 km),
and again at 500 miles (800 km) of new vehicle operation and after any wheel disturbance (tire rotation, changing a flat
tire, wheel removal, etc.).
❑Refer toWheel Lug Nut Torque Specificationin yourOwner’s Guidefor the proper lug nut torque specification.
