Pretrip Inspection Checklist
The following pretrip inspection checklist helps ensure
that the vehicle components are in good working condi-
tion before each trip.
Pretrip inspections cannot be performed in a short pe-
riod. In checklist form, the sequence below may seem
to be overly time-consuming. However, careful pretrip
inspections save time by eliminating stops later to ad-
just items overlooked or forgotten.
Each checklist step corresponds with detailed instruc-
tions found under "Pretrip Inspection and Daily Mainte-
nance Procedures." If any system or component does
not pass this inspection, it must be corrected before
operating the vehicle. Refer to the
Cargo Workshop
Manual
for repair procedures, and to the
Cargo Mainte-
nance Manual
for lubricant recommendations, specifica-
tions, and maintenance intervals and procedures.
NOTE: Apply the parking brakes and chock the
tires.
1. Drain the air brake system air reservoirs.
2. Inspect the batteries and battery cables.
3. Check the fluid level in the windshield washer res-
ervoir.

oil-lubricated wheel bearings.
5. Tilt the cab. Examine the steering gear compo-
nents.
6. Check the coolant level in the surge tank sight
glass and check the radiator and air-to-air after-
cooler cooling fins for clogging or damage. Check
the radiator for coolant leaks.
7. Check the condition of the coolant hoses and
heater hoses.
8. Check the condition of the drive belts.
9. Inspect the engine for fuel, oil, and coolant leaks.

reservoir if equipped.
13. Check the engine oil level.
14. Check the oil level in the automatic transmission if
