VEHICLE INSPECTION
INFORMATION
To make 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 verify a
proper vehicle inspection procedure.
WARNING: Exercise great caution
when working on a 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 starts at
this 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. WARNING:
Do not operate the
vehicle if any suspension conditions
listed in the following charts are evident.
Loss of steering or suspension could
result in property damage, personal injury
or death. WARNING:
If a wheel must be
changed, obtain expert tire service help.
Mounting and un-mounting of tires
should only be performed by a qualified
technician using necessary safety
procedures and equipment, otherwise
the result could be property damage,
personal injury or death.
Note: Always make sure you apply the
parking brake before starting the engine. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See
Engine Oil Dipstick (page 223).
Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 237).
Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check
(page 244).
Power steering fluid
Remove the master cylinder caps and inspect the fluid level.
See
Brake Fluid Check (page 243).

2022 F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Vehicle Inspection Guide
Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm)
Belts (fan, alternator,
water pump and air
conditioning
compressor)
Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine.
Fluid leaks
Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance.
HVAC air inlet Engine starting (with parking brake applied)
Before 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.
Safety and emergency
equipment
Walk around the vehicle and verify 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.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is in
neutral (N) or park (P) (if equipped with a park position).
Starting the engine
Diesel engine:
Turn the key to the on position. Turn the key
to start when the wait to start indicator light in the instrument
cluster turns off.
Gasoline engine:
Turn the key to start, and then release it
as soon as the engine starts.
Verify pressure builds to normal operating range.
Engine oil pressure
A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches
70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115– 130 psi (793–896 kPa)
.
Low air pressure warning
tone (if equipped with an
air compressor)
Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately.

Front 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 Front wheels
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
Inspect wheel hub oil seal for leaks and, if sight glass if
present, verify the oil level is adequate.
Hub oil seals
Inspect for proper lubrication level if the hubcap has a trans-
parent window. If the hubcap does not have a transparent
window, remove the rubber fill-plug and inspect for proper
level.
Oil-lubricated front
wheel bearings Fuel area
Verify the tank(s) and cap(s) are secure and that there are
no leaks from the tank(s).
Fuel tank(s)
Inspect for leaks from the tank(s).

To check the engine oil level consistently
and accurately, do the following: 1.
Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See Opening and
Closing the Hood (page 219).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 221).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 223).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Engine Oil
Capacity and Specification (page
290).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
