To be 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 ensure a proper vehicle inspection procedure. The pages in
this section may be produced locally and used on a regular basis.
VEHICLE INSPECTION INFORMATION
Note:Always make sure the parking brake is applied before starting the
engine.
Engine compartment (with engine stopped)
Engine oil level:Use the engine oil dipstick to verify that the
engine oil level is between the ADD and
OPERATING RANGE marks.
Engine coolant
level:Look through the plastic reservoir or the clear
sight glass on the reservoir, depending upon
vehicle equipment, and make sure the fluid is
within the minimum and maximum fluid level
range as marked on the reservoir.Do not
remove pressure cap until the coolant has
cooled.
Power steering fluid:Verify that the fluid level is between the
proper operating range Refer toPower
steering fluidin theMaintenance and
Specificationschapter.
Brake fluid (master
cylinder):Remove the master cylinder caps and inspect
the fluid level. The full mark is at the bottom
of the opening of the port ring.
Hydraulic clutch
fluid:Check for adequate amount of hydraulic clutch
fluid. Fluid level should be at the step of the
reservoir; refer toClutch fluid/linkage
adjustmentsin theMaintenance and
Specificationschapter.
Belts (Fan,
alternator, water
pump and A/C
compressor):Check for glazing, fraying or cracking. There
should be no more than five - seven cracks per
rib per inch.

Engine starting (parking brake applied)
Starting the engine:Verify the parking brake is set. Depress the
clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral. Vehicles equipped with an automatic
transmission should be in N (Neutral) or P
(Park) if equipped with a Park position.
When the WAIT TO START indicator light in
the instrument cluster turns off, turn the key
to START.
Oil pressure builds:Make sure engine oil pressure is building to
normal operating range.
Air chime sounds (if
equipped with air
compressor):The low air pressure warning chime should
sound immediately after the engine starts but
before the compressor has built up pressure.
The low air pressure warning chime should
stop when the air pressure reaches 70 psi
(483 kPa) (or more). Let the air pressure
build to governed cut-out pressure, which
should occur between 115–130 psi
(793–896 kPa).
Accelerator:Depress the accelerator and verify that it
operates smoothly without any binding or
irregular feel. Remove your foot from the
pedal and make sure the engine returns to idle
speed immediately.
Ammeter/Voltmeter:Check the gauge to see if the alternator is
charging.
Steering linkage
free play:Check for excessive free play in the steering
linkages. The steering wheel should have less
than two inches (five cm) of free play at rim
of steering wheel.
Hydraulic brake
check:When the engine is off, the pump will turn on
if the brake pedal is applied, or if the ignition
is turned to the ON position.

Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (as indicated by the
arrows). If the needle falls below
the normal range, stop the vehicle,
turn off the engine and check the
engine oil level. Add oil if needed. If
the oil level is correct, have your
vehicle checked at your dealership
or by a qualified technician.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range (as
indicated by arrows), have the
vehicle’s electrical system checked
as soon as possible.
Transmission fluid temperature
gauge (if equipped, automatic
transmission only):
Indicates the temperature of the
transmission fluid. The normal
temperature range is 150°–230°F
(65°–110°C). Readings of
230°–250°F (110°–121°C) are
satisfactory for intermittent
operation and are not cause for
alarm. Operation above 250°F
(121°C) can cause the fluid to break down and will result in component
damage.

•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure; this
should be indicated on the gauge
within 15 seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to 10
minutes. Excessive idling reduces
fuel economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Cold weather operation
Do not use volatile starting aids such as ether, propane or
gasoline in the engine air intake system. Glow plugs may ignite
vapors which can cause engine damage or personal injury.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they’re in
optimum condition.
•Use a permanent-type engine coolant solution to protect the engine
against damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level.
•At temperatures of –4°F (–20°C) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Note:Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause

get out of the vehicle and visually check the intended path is clear;
back-up slowly as to allow others time to move, if necessary.
If an electrical back-up alarm is installed, it should be connected to the
back-up lamp circuit.
Parking your vehicle
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires will act against the curb to stop the vehicle. The front
wheels will be more effective at stopping a rolling vehicle than the rear
wheels.
When parking your vehicle, do not leave the transmission in
gear; if the key is in the ON position and the vehicle rolls, the
engine could start. Failure to follow these instructions could result in
an unattended vehicle moving, possibly causing personal injury or
property damage.
Driving through water
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine, drive axles or the transmission
(through the breather ports).
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.
ENGINE AUTOMATIC SHUTDOWN WARNING LIGHT OR CHIME (IF
EQUIPPED)
Your vehicle may be equipped with an automatic shutdown feature that
stops the engine in the event of high coolant temperature, low engine oil
pressure, high diesel particulate filter soot loading or low engine coolant
level. A warning light in the instrument cluster and a warning chime will
indicate high engine coolant temperature, low engine oil pressure or the
need to have the diesel particulate filter cleaned or serviced. If the
engine coolant temperature becomes too high, engine oil pressure too
low or the diesel particulate filter too restricted, the engine will
automatically shut down.

If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Choosing the right fuel
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel in your diesel engine. The engine and exhaust
system were designed to only use this fuel. Look for the
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm Sulfur
Maximum) label on fuel pumps when purchasing your fuel.
Number 1-D or winter blend number 2-D fuel is recommended at
temperatures below 20°F (-7°C) (seeCold weather operationin the
Drivingchapter. Diesel fuel containing no more than 5% biodiesel may
be used. Biodiesel fuel is a product that has been converted from
renewable fuel sources, including vegetable oil, animal fat and cooking
oil. Raw or refined vegetable oil, animal fat, cooking oil or recycled
greases should not be used.
Since it is normal for a small amount of unburned fuel to enter the
crankcase and mix with the engine oil, the use of biodiesel requires that
the engine oil and filter be changed more often. Refer to theExceptions
section of theScheduled Maintenance Guidechapter for more
information.
Do not use home heating oil or any diesel fuel not intended for
highway use. Red dye is used to identify fuels intended for
agricultural and non-highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.

When installing wheel balance weights, they must be mounted on the
dome-side of the wheel only. Failure to do so may result in loss of wheel
weight and/or damage to brakes or wheels.
Important:Remember to replace the wheel air valves when the road
tires are replaced at the end of their useful life.
Oil lubricated front wheel bearings
During normal vehicle duty cycle, the lube and air inside the hub/wheel
cavity expands and if not vented, causes pressure build-up that could
cause accelerated seal wear.
There are two venting methods:
•a slit or small hole in the rubber check vent or
•the window
You can use either of these methods to prevent pressure build-up.
Normal maintenance
Over a period of time, if not routinely cleaned, a slight film of oil can
collect dirt around the rubber fill plug and face, which could appear to
be a leak. Routine cleaning ensures that the lube level can be easily
observed through the clear window as intended. In situations where the
window is clean on the outside but discolored on the inside, the lube
level may be checked by inserting a finger through the rubber check
vent hole.
The specified lube level for a clear window type hubcaps is from the
minimum line to + 5/16 inch above the minimum line.
If the lube level should suddenly drop dramatically below the minimum
level, see theWorkshop Manualfor diagnostic procedure.
Installation, tightening and alignment
When installing wheels, be certain that the threads on studs and nuts are
clean to permit correct torque. The mounting surfaces of rims, wheels,
spacer rings and clamps must be free of dirt, rust, lubricants or damage.
Use a wire brush to clean the mounting contact surfaces. Do not use
lubricant on threads.
After the rim or wheel has been properly tightened, it should be checked
for alignment. Rotate the wheel with a piece of chalk attached to a
steady, firm surface, and placed to just barely clear the outside surface of
the tire bead seat. This procedure will point out the high spot. A high
spot does not necessarily mean that the lug nuts have been unevenly
tightened. This condition or misalignment could be caused by a bent
wheel.

Maintenance and Specifications
197

Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a catalytic converter-muffler. Waste lube oil blending in fuel will plug the
catalytic converter-muffler, resulting in a significant loss of engine power.
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.
NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulations became effective governing the
noise emissions on trucks over 10,000 lb. (4,536 kg) GVWR. The
following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the Warranty Guide,
and are applicable to completed trucks.
Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative, by any person other than for purposes
of maintenance, repair or replacement, of any device or element of
design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use,
or (2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
