6. Turn the ignition key to the START position
and operate the starter until fuel, free from air,
comes from the injector and Thermo Start fuel
line fittings. Turn ignition switch OFF. Tighten
all fittings.
7. Close and lock both access doors. The
engine is now ready to start.
If the engine runs correctly for a short time and
then stops or runs roughly, check for air in the fuel
system. If there is air in the fuel system, there is
probably a leak in the low pressure system.

Sodium Carbonate Mixture
and Refill with Coolant

the left rear engine access door.
All checks or inspections listed under daily or
previous maintenance intervals must also be
performed at this time in addition to those listed
under this maintenance interval.
Warning
• To prevent personal injury, never remove the
radiator cap when coolant is above 120 °F
(49 °C). Always turn the cap slowly to the
first stop and allow pressure to escape
before you remove cap completely. Hot
coolant spray can burn you and injure your
eyes. Wear safety glasses.
• To avoid severe burns, DO NOT attempt this
procedure when engine is hot. Wait for
engine, muffler, and tail pipe to cool before
proceeding.
2. Slowly turn the radiator cap to the first stop,
allow pressure to escape, then continue to
turn and remove the cap.
3. Attach a hose to petcock at bottom left corner
of radiator, Fig. 8A.17. Place the other end of
the hose into a 5 gallon (18,9 liters) or larger
container. Open petcock and drain coolant
from the system.
NOTE: If engine is turbocharged, disconnect hose
lines to oil cooler in lube oil filter, drain coolant into
the container, and flush cooler and reconnect the
hose lines (see paragraph 8A.11.4).
