(1.3 US gal) per minute to avoid air locks.
Cooling system air locks may result in engine
damage.
3.
Fill the cooling system with clean water.
Loosen the air vent (4) in the aftercoolers. Fill the
cooling system until coolant free of air flows from
the vent . Tighten the air vent securely.
Install the cooling system filler cap (1).
4.
Start the engine. Operate the engine until the
temperature reaches 49 to 66 °C (120 to 150 °F).
5.
Stop the engine. Allow the engine to cool. Loosen
the cooling system filler cap (1) slowly to relieve
any pressure. Remove the cooling system filler
cap. Open the drain cock or remove the drain plug
(2) in the cylinder block. Open the drain cock or
remove the drain plug on the radiator. Open the
drain cocks or remove the drain plugs (3) in the oil

5.
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.
