Vehicle Inspection Guide

Diesel Exhaust Fluid (DEF) area
Verify the tanks and caps are secure and that there are no
leaks from the tanks. DEF tanks
Inspect for leaks from the tanks. Leaks
Underbody
Verify that the driveshaft is not bent or cracked and that all
driveshaft couplings are secure. Driveshaft
Verify that the visible outside parts are securely mounted and
that there are no cracks, holes or severe dents. Exhaust system
Inspect for cracks or bends in longitudinal frame members.
Verify there are no loose, cracked, bent, broken or missing
crossmembers or crossmember fasteners. Frame
Rear of vehicle
Verify there are no cuts, cracks, chafing or wear on the air
hoses and electrical line insulation. Listen for audible air leaks. Air hoses and electrical
lines
Verify air and electrical lines are not tangled, crimped or
pinched or being dragged against any truck parts. None of
the air or electrical line should be spliced or taped.
Inspect for corrosion on pins and in electrical sockets to verify
continuity and reduced heat build-up potential.
Verify the deck plate is clean, bolted securely to the frame
and is clear of loose objects. Deck plate
Verify that both brake lights illuminate when the pedal is
applied, each signal flashes and that the four-way flashers
work properly. Turns signals, brake
lights and flashers
Verify all exterior lights illuminate and are clean. Lights and reflectors
Verify reflectors are clean, unbroken and of proper color (red
on rear, amber elsewhere).

Vehicle Inspection Guide

Rear brakes
Inspect for cracked, worn or frayed hoses, and that all coup-
lings are secure. Hoses
Verify that there are no cracks or dents, and that the cham-
bers are securely mounted. Brake chambers
Inspect for broken, loose or missing parts. Slack adjusters
Note: The angle between the push rod and adjuster arm
should be approximately 90 degrees when the brakes are
applied. When pulled by hand, the push rod should not move
more than approximately 1 in (2.5 cm).
Verify that there are no cracks, dents, holes, and no loose or
missing bolts and that the brake linings are not worn,
dangerously thin or contaminated by lubricant. Drums
Rear wheels
Check for even separation of dual wheels, and that the tires
are not touching each other. Spacers
Inspect for damaged or bent rims. They should not have
welding repairs, and there should be no rust trails, which
indicate it is loose on the wheel. Rims
Verify all lug nuts are present and not loose (look for rust
trails around the lug nuts). There should be no cracks radiating
from the lug bolt holes or distortion of the bolt holes. Lug nuts
Trailer
If you are pulling a trailer, perform an
inspection of the trailer similar to that of
the tractor. The inspection should follow
trailer manufacturer recommendations
and should include at a minimum: general
condition, landing gear, doors, sides, lights,
reflectors, suspension, brakes, tires,
wheels, cargo placement, stability and
tie-downs.
Transmission
WARNING: If the unit starts in gear
and/or the neutral start switch is not
functioning correctly, the vehicle may
inadvertently move which could result
in property damage, personal injury or
death.
Regularly inspect the transmission's
neutral start switch. The engine should
only start in neutral (N) or park (P) (if
equipped with a park position).

Vehicle Inspection Guide

2. Reconnect the fuel lines.
3. Switch the ignition on for 30 seconds
and then switch the ignition off.
Repeat this operation six times in a row
to purge any trapped air from the fuel
system.
ELECTRICAL SYSTEM
INSPECTION
Periodically inspect electrical connectors
on the outside of the cab and 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 Silicone Brake Caliper
Grease and Dielectric Compound 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 powertrain components,
such as engine and transmission controls,
instrument panels and ABS. While most
systems operate on battery voltage (12
volts), some systems can be as high as 90
volts or as low as five volts. See the
Electrical Circuit Diagram Manuals,
available from your vehicle’s manufacturer,
to make sure that any extra body lights and
accessory connections to circuits are both
appropriate and not overloaded. Do not
make modifications to any vehicle control
system without first contacting an
authorized dealer.
AIR INDUCTION SYSTEM
INSPECTION
WARNING: When performing
maintenance to any turbocharged engine
with engine air inlet piping disconnected,
keep loose clothing, jewelry and long hair
away from the engine air inlet piping. A
turbocharger compressor air inlet
protective shield should be installed over
the turbocharger air inlet to reduce the
risk of personal injury or death.
Perform a complete inspection of the air
induction system annually.
In areas where road salt is used,
disassemble the joints of each aluminum
component and inspect for salt build-up
and presence of chlorine that can cause
aluminum particles to flake off and enter
the engine combustion chambers. If
evidence of corrosion is found (usually at
the pipe connections), use a wire brush to
clean the inside of the pipes and inside the
rubber hoses.
If pitting is evident at the joint ends of the
intake pipes, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the
joints. Make sure no excess material, which
can pull into the engine, is on the inside of
the pipes. If the service condition of the
pipes, hoses or clamps is questionable,
replace the defective part(s).
Make sure to clean all dust and debris out
of the pipes and couplings with a clean,
damp rag before reassembly.
Chassis-mounted Charge Air
Cooler
Visually inspect the core assembly for
debris and clogging of external fins with
the engine off.

BULB SPECIFICATION CHART
Replacement bulbs are specified in the
chart below. Headlamp bulbs must be
marked with an authorized “D.O.T.” forNorth America and an “E” for Europe to
ensure lamp performance, light brightness
and pattern and safe visibility. The correct
bulbs will not damage the lamp assembly
or void the lamp assembly warranty and
will provide quality bulb illumination time.

ENGINE OIL CAPACITY AND
SPECIFICATION - 6.7L DIESEL
Use oil that meets the defined
specification and viscosity grade.If you do not use oil that meets the defined
specification and viscosity grade, it could
result in:
• Component damage that your vehicle
warranty does not cover.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced vehicle performance.
• Reduced fuel economy.
292
Capacities and Specifications

There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle’s
time out of service.
Air Brake Adjustment
WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters
WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the
automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
Check Every Month
Air filter restriction gauge.1
Engine oil level.
Fuel and water separator. Drain if necessary, or if indicated by the information display.
