REPAIR INSTRUCTIONS
Page 307
Cooling System
1. Check the cooling system. Make sure all
plugs are installed and tight. Make sure the
thermostat is installed.
2. Fill the system with the recommended
coolant.
To ensure that all air is purged from the cooling
system, remove a plug from the top (or end) of
the coolant manifold during filling. This will
eliminate any air that is trapped as a result of
rapid filling.
3. Install a new coolant conditioner and fill with
the recommended coolant mixture.
4. Check that all plugs and thermostat(s) are
installed.
Fuel System
GENERAL INSTRUCTIONS
1. Check the fuel system to ensure that all
connections are tight.
2. Remove any trapped air by operating the
manual priming pump located on the side of
the fuel supply pump, using the following
procedure.
Prime the fuel system with clean, Grade 2D
diesel fuel (DF-A).
PRIMING THE FUEL SYSTEM
Using a hand-priming pump is usually only
necessary when the fuel system has run dry. If
the hand-priming pump is needed, use the
following procedure for priming a dry fuel system.
1. Fill the primary and secondary fuel filters.
2. Disconnect the inlet hose at the secondary
fuel filter. (This is the center fitting on the
CH/CL fuel filter mounting adapter.)
3. Hand-prime until fuel is seen at the inlet
hose fitting. This should take approximately
50 hand pumps.
Excessive hand-priming after fuel is seen at the
fitting may make the engine difficult to start.
4. Reconnect the inlet hose to the secondary
fuel filter and start the engine.
If the engine does not start, refill both filters and
repeat the priming procedure outlined in steps 2,
3 and 4.
Do not crank the engine continuously for more
than 30 seconds without allowing the starter to
cool for 2 minutes between cranks.
The only acceptable method of priming the fuel
system is the hand primer pump. The application
of air pressure to the fuel tank or the use of an
auxiliary pump to prime the fuel system is
PROHIBITED. These priming techniques may
result in severe engine damage caused by
leakage of fuel past the supply pump seal and
into the crankcase.
Engine Operational Check
1. Remove all tools from the engine
compartment.
2. Connect the battery cables (negative cable
last).
3. Clear the work area of debris and personnel.
4. Start the engine. Check for leaks and
monitor gauges for satisfactory oil pressure,
etc.
5. After several minutes, shut the engine down.
Check the fluid levels and fill to capacity
before restarting the engine.
6. Refer to the Rebuilt Engine Run-In
Procedures in this section for testing
procedures.
