For the m axim

thorough inspection within the engine compartment
before the engine is started. Look for the following
items: oil l
eaks, coolant leaks, loose bolts, and
excessive dirt and/or grease. Remove any excess
dirt and/or grease buildup. Repair any faults that
were ident

Inspect the cooling system hoses for cracks and
for loose c

Check the fuel supply. Drain water from the water
separator
(if equipped). Open the fuel supply valve
(if equipped).
NOTICE
All valve
s in the fuel return line must be open before
and during engine operation to help prevent high fuel
pressure. High fuel pressure may cause filter housing
failure o
r other damage.
If the engine has not been started for several weeks,
fuel may h
ave drained from the fuel system. Air
may have entered the filter housing. Also, when fuel
filters have been changed, some air pockets will be
trapped
in the engine. In these instances, prime the
fuel system. Refer to the Operation and Maintenance
Manual, “Fuel System - Prime” for more information
on primi
ng the fuel system.
Engine exhaust contains products of combustion
which may be harmful to your health. Always start
