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 assure 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 FULL and ADD
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 full
and refill marks.
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.
Fan, alternator,
water pump/drive
belt:Press belt to test that it is snug. Check for
frays, cracks, loose fibers or visible signs of
wear. If it deflects more than 1.25 cm–2cm
(1/2–3/4 inch), slippage is probably excessive.
Air compressor:Check belts (if equipped). Same for water
pump.
Refrigerant
compressor:Check belts (if equipped). Same for water
pump.

Engine compartment (with engine stopped)
Any leaks:Check for signs of fluid puddles, dripping fluid
on the ground under the engine or the
underside of the engine.
HVAC air inlet:Check for debris, leaves, etc. that may have
collected on the HVAC air inlet grille or inside
the exterior module as this may cause reduced
system performance.
HVAC fresh air filter
(if equipped):Periodically check the HVAC fresh air filter for
cleanliness.
Exercise great caution when working on 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 will start at these 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.
Engine starting (with parking brake applied)
Safety/Emergency
equipment:Prior to entering the cab, verify that the
vehicle is equipped with spare electrical fuses
(if used), three red reflective triangles, a
properly charged and rated fire extinguisher
and wheel chocks. Walk around the vehicle
and check that all steps and grab handles,
inside and out as well as behind, are tight and
clean. Use extreme caution and a three-point
stance at all times. Check door latches for
positive closing, latching and locking.
Clutch/Gearshift:Depress the clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral before turning on the starter. Keep the
pedal depressed until the engine reaches idling
speed.
Oil pressure builds:Make sure engine oil pressure is building to
normal operating range.

temperature. At normal operating
temperature, the needle will be in
the normal range (between“H”and
“C”).If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine
and let the engine cool.
Never remove the coolant reservoir cap while the engine is
running or hot.
Odometer:Registers the total
kilometers (miles) of the vehicle.
Trip odometer:Registers the
kilometers (miles) of individual
journeys. To reset, depress the
control.

After the engine starts:
•On some engines, theWait to
startlight should illuminate after
the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
Wait to startlight cycles off to indicate the air intake heater has shut
off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.
•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
•Ensure engine oil pressure is
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.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and specificationschapter.
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 0°C (32°F) 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–20°C(–4°F) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of–29°C (-20°F) 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
a buildup of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
The following cold weather idling guidelines must be followed:
•Avoid idling the engine for more than 10 minutes at a time.
•Use a minimum of 45 Cetane Diesel fuel or use Cetane Index
improvers from a reputable manufacturer.
•Maintain a minimum idle of 1250 RPM by using the hand throttle.
Always make sure that the parking brake is applied and the
transmission is in neutral before applying the hand throttle.
•Maintain the engine cooling system properly.
•Do not shut the engine down after an extensive idling period (10
minutes or more). Drive the vehicle under load for several miles at
normal operating temperatures to burn off any accumulated carbon
and varnish.
•Consider using an engine block heater, approved winter fronts and/or
radiator shutters where conditions warrant.
Winter fronts
The use of winter fronts, or other air-restrictive devices mounted in front
of the radiator on vehicles with chassis-mounted charge air coolers, are
not recommended unless extremely cold weather conditions exist. Air
flow restriction can cause high exhaust temperatures, power loss,
excessive fan usage and a reduction in fuel economy. If you insist on
using a winter front, the device should have a permanent opening of at
least 774 sq. cm (120 sq in.) directly in line with the fan hub.

Hot weather operation
•Keep the engine cooling system filled with a clean, permanent coolant
solution to protect against damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
Above normal coolant temperatures could be experienced while driving
in a transmission gear ratio which lugs the engine. To correct this
problem, engine speed should be increased by downshifting in to the
next lower gear to increase engine RPM.
Starting a turbocharged engine with the vehicle on a steep grade
When starting a naturally aspirated Diesel engine when the loaded
vehicle is on a grade, the engine RPM will start to fall slightly when the
clutch is engaged, but quickly recovers as the vehicle begins moving.
Turbocharged Diesel engines act differently; once the clutch is engaged,
the engine RPM will fall significantly. When the engine RPM first falls, do
not disengage the clutch and try to increase engine RPM as this may
damage driveline components. After the initial drop in engine RPM, the
engine will recover by itself and accelerate in a normal manner.
GENERAL OPERATING INSTRUCTIONS
•Start the vehicle in motion by using the highest gear speed in the
transmission that will let the engine easily start the load without
slipping the clutch.
•Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•When approaching a hill, depress the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle
speed.
•When going down a hill, or long steep grades, prevent over-speeding
of the engine. The engine governor has no control over engine speed
when it is being pushed by a loaded vehicle.

4. Tilt the hood forward until
stopped by the retaining cables.
To lower the hood:
1. Push the hood rearward at the top center of the hood above the grille
until closed.
2. Engage the latch on each fender.
3. Push down on the bottom of each latch until locked.
To reduce the risk of the possibility of personal injury, never
stand beneath the hood when it is being raised or lowered.
ENGINE OIL
Checking engine oil level—Cummins B and Caterpillar engines
Refer to the appropriate engine operator’s manual for information on the
engine oil.
Checking engine oil level—6.0L Power Stroke engine
Refer to the general maintenance information section for the appropriate
intervals for checking the engine oil.
Check the engine oil level consistently and accurately. The following
procedure is recommended:
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. Park the vehicle on level ground.

ENGINE COOLING SYSTEM
Inspect cooling system daily
Note:The de-aeration tank requires air space for expansion volume. The
proper fill level is identified on the reservoir; do not overfill the reservoir.
To reduce the risk of personal injury or death, use only the
following procedure to remove the pressure-type cap from the
radiator or expansion tank.
1. Always allow the engine to cool first.
2. Wrap a thick, heavy cloth around the cap.
3. Loosen the cap slowly, then pause a moment. This will reduce the risk
of possible scalding by hot water or steam.
4. Continue to unscrew the cap and remove only after pressure in the
radiator is fully released.
Note:If the coolant should get extremely low and the engine very hot,
let the engine cool for approximately 15 minutes before adding coolant.
After the engine has cooled, start the engine and add coolant slowly.
Adding coolant to a hot engine may crack the cylinder head or
crankcase. Never use only water to fill the cooling system.
Adding engine coolant - 6.0L Power Stroke
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the“cold full”level. For all other vehicles, which have a coolant
degas system with a pressurized cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator of a vehicle with an overflow
system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.

Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the“cold fill range”or the“cold full”level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration (refer
toCoolant condition inspectionlater in this section). If the
concentration is not 50/50 (protection to–34°F/–36°C), drain some
coolant and adjust the concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
