Open the drain cock or remove the drain plug (1)
on the engine. Open the drain cock or remove the
drain plug on the radiator.
Allow the coolant to drain.
NOTICE
Dispose of used engine coolant or recycle. Various
methods have been proposed to reclaim used coolant
for reuse in engine cooling systems. The full distillation
procedure is the only method acceptable by Perkins to
reclaim the coolant.
For information regarding the disposal and the
recycling of used coolant, consult your Perkins dealer
or your Perkins distributor.

Fill the cooling system with clean water. Install the
cooling system
fi
ller cap.
4.
Start and run the engine at low idle until the
temperature reaches 49 to 66 °C (120 to 150 °F).
5.

Coolant (ELC). Refer to the Operation and
Maintenance Manual, “Fluid Recommendations”
topic (Maintenance Section) for more information
on cooling system speci
fi
cations. Do not install the
cooling system
fi

idle for one minute in order to purge the air from
the cavities of the engine block. Stop the engine.
4.
Check the coolant level. Maintain the coolant level
within 13 mm (0.5 inch) below the bottom of the
pipe for
fi
lling. Maintain the coolant level in the
expansion bottle (if equipped) at the correct level.
