• Make sure there is proper overhead clearance for
exhaust stacks, air deflectors, or other attachments
above the cab.

Check the engine coolant level to be sure it is filled to the
proper level.
Warning: Check the coolant level only when the engine
is stopped. Wait until the coolant temperature is below
50°C [120°F] before removing the pressure cap. Failure
to do so can cause personal injury from heated coolant
spray.
Caution: Do not add cold coolant to a hot engine. This
can cause engine casting damage. Allow the engine to
cool to below 50°C [120°F] before adding coolant.
Check the engine lubricating oil level to be sure it is filled
to the proper level.
NOTE: Use a known source of ‘‘good’’ quality No. 2 diesel
fuel. This is very important since No. 1 diesel fuels, along
with most other alternate fuels, are lighter (lower specific
gravity, higher API gravity) than No. 2 diesel fuel. The lighter
the fuel, the lower the energy content (BTU) per gallon (liter,
etc).
