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.

•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.

3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission).
4. Turn off the engine and wait a few minutes for the oil to drain
completely into the oil pan.
5. Open the hood. Protect yourself from engine heat.
6. Locate and carefully remove the
engine oil level indicator (dipstick).
7. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween FULL and OPERATING RANGE,the oil
level is acceptable.DO NOT ADD OIL.
•Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required.
•The distance from ADD to OPERATING RANGE on the dipstick
represents 1.9L (2.0 quarts).
•Oil levels above OPERATING RANGE may cause engine damage. Some
oil must be removed from the engine by a qualified service technician.
8. Put the indicator back into the engine and ensure it is fully seated.

Fuel filter replacement - Caterpillar engine
The fuel filter/water separator is
located on the left side of the
engine. Replace the fuel filter/water
separator as recommended in the
general maintenance information
section, or sooner if it becomes
plugged. Vehicles operated on fuel
with more than average impurities
may require replacement of the fuel
filter more frequently. The spin-on
filter has a water drain valve built
into the bottom of the filter canister.
Removal
1. Using an oil filter wrench, remove the filter.
2. Carefully clean the mating surfaces.
Installation
1. Fill the filter with clean, fresh diesel fuel.
2. Coat the filter seal with clean, fresh diesel fuel.
3. Hand-tighten the filter until it seats firmly against the mount, then
tighten (by hand) an additional
1⁄3to1⁄2turn.
4. Start the engine and check for fuel leaks.
Fuel filter replacement - 6.0L Power Stroke engine
Your vehicle is equipped with two fuel filters; one mounted on top of the
engine and the other is mounted inside the frame rail under the
driver-side floorboard near the transmission. Both filters should be
replaced at the same time.

Cooling System
•Check the fan for damage to blades; replace, if damaged, with the
recommended parts. Inspect for fan to shroud interference, and any
damage to shroud such as cracks and holes.
•The fan ratio should not be changed and the fan spacer dimensions
and positions should not be altered.
•Inspect the fan clutch for proper operation, make sure that the fan is
disengaged when cooling of the engine is not required.
•Check for proper operation of radiator shutters, if equipped. The
shutters should be open during normal operating temperatures.
Engine and Driveline System
•Transmission Enclosure:inspect for cracks, holes, and tears. Clean
any deposits such as oil, dirt, and stones.
•Engine valve covers and block covers are made to damp out engine
mechanical noise and, if needed, should be replaced with
recommended parts. Check for mechanical isolations.
Exhaust System
•Inspect the exhaust system for leaks at various joint connections and
tighten the clamps.
•Do a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended parts when items need to be replaced.
•The tail pipe elbow or offset tail pipe orientation must not be changed
from the standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for
the owner to perform inspections and necessary maintenance at the
intervals shown in theGeneral Maintenance Informationsection.
CHASSIS-MOUNTED CHARGE AIR COOLER
Inspect charge air cooler daily
With the engine off, visually inspect the charge air cooler core assembly
for debris and clogging of external fins. Prior to engine operation,
remove any debris blocking the core.

Inspect air intake piping
•Check for accumulation of salt deposits (where applicable). If present,
disassemble and clean the complete air intake piping system. If the
intake piping is pitted, use RTV silicone to seal joints against leakage.
•Check for loose hoses and clamps.
•Check for ruptured or collapsed hoses.
•Check air cleaner housing for cracks.
ELECTRICAL SYSTEM INSPECTIONS
Periodically inspect electrical connectors on the outside of the cab, on
the engine and frame for corrosion and tightness. Exposed terminals
such as the fuel sender, cranking motor, alternator and feed-through
studs should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft XG-3, or equivalent. This should include the ground
cable connector for batteries, engine and cab as well as the jump starting
stud.
Accessory feed connections
Vehicle electrical systems are complex and often include electronic
components such as engine and transmission controls, instrument panels,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle’s
manufacturer, to assure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.
SUSPENSION INSPECTION
Note:Do not adjust air suspension height to any setting other than the
specified setting. Altering the height setting will change the driveline
angle and may result in unwarrantable component damage, such as
transmission component damage.
Verify drive axle air suspension height and height control valve
performance at engine lube oil change intervals.
Periodically:
•Check condition of spring leaves for evidence of fatigue, bending or
breakage.
•Check condition of suspension mounting brackets and bushings.
