4. Remove the plug (6) on the water temperature
regulator on bank A and plug (7) on the water
temperature regulator on bank B to allow air in the
cooling system to vent to avoid air locks during
filling.
NOTICE
Do not fill the cooling system faster than 5 L
(1.3 US gal) per minute to avoid air locks.
Cooling system air locks may result in engine
damage.
5. Using a pump, fill the cooling system with Perkins
(ELC). Refer to the Operation and Maintenance
Manual, “Fluid Recommendations” topic
(Maintenance Section) for more information on
cooling system specifications.
6. When coolant starts leaking from the plug (4) on
the oil cooler, tighten the plug securely and
continue to fill the cooling system.
7. When coolant starts leaking from the plug (5) on
the oil cooler, tighten the plug securely and
continue to fill the cooling system.
8. When coolant starts leaking from the plug (6) on
the water temperature regulator, securely tighten
the plug and continue to fill.
9. When coolant starts leaking from the plug (7) on
the water temperature regulator, securely tighten
the plug and continue to fill until the cooling
system is full.
Note: Ensure that the filler cap is installed before
operating the engine.
10. Install power to the engine. Start the engine.
Operate the engine to purge the air from the
cavities of the engine block. Use the normal
shutdown procedure to stop the engine.

Remove the filler cap. Check that the coolant level
is within 25 mm (1.0 inch) of the bottom of the filler
pipe.

12. Clean the cooling system filler cap (1) and inspect
the seal (2). If the seal is damaged, discard the old
filler cap and install a new filler cap. If the seal is
not damaged, use a suitable pressurizing pump to
pressure test the filler cap. The correct pressure is
stamped on the face of the filler cap. If the filler
cap does not retain the correct pressure, replace
the filler cap.
Install the cooling system filler cap.
13. Install power to the engine. Start the engine.
Operate the engine. Inspect the cooling system for
