to remove any debris.
2. Close the drain cock or install the drain plug in the
engine. Close the drain cock or install the drain
plug on the radiator.
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.
3. Fill the cooling system with clean water. Install the
cooling system filler cap.
4. Start and run the engine at low idle until the
temperature reaches 49 to 66 °C (120 to 150 °F).
5. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly in
order to relieve any pressure. Remove the cooling
system filler cap. Open the drain cock or remove
the drain plug on the engine. Open the drain cock
or remove the drain plug on the radiator. Allow the

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.
2. Fill the cooling system with Extended Life Coolant
(ELC). Refer to the Operation and Maintenance
Manual, "Fluid Recommendations" topic
(Maintenance Section) for more information on
cooling system specifications. Do not install the
cooling system filler cap.
3. Start and run the engine at low idle. Increase the
engine rpm to high idle. Run the engine at high
idle for 1 minute in order to purge the air from the
cavities of the engine block. Stop the engine.
Cooling System Coolant Extender (ELC) - Add
4. Check the coolant level. Maintain the coolant level
within 13 mm (0.5 inch) below the bottom of the
pipe for filling. Maintain the coolant level in the
expansion bottle (if equipped) at the correct level.
5. Clean the cooling system filler cap. Inspect the
gasket that is on the cooling system filler cap. If
the gasket that is on the cooling system filler cap is
damaged, discard the old cooling system filler cap
and install a new cooling system filler cap. If the
gasket that is on the cooling system filler cap is not
damaged, use a suitable pressurizing pump in
order to pressure test the cooling system filler cap.
The correct pressure for the cooling system filler
cap is stamped on the face of the cooling system
filler cap. If the cooling system filler cap does not
retain the correct pressure, install a new cooling
system filler cap.
6. Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.
Cooling System Coolant
Extender (ELC) - Add
In order for Perkins ELC to achieve 12000 hours an
extender must be added at 6000 hours. For a
suitable extender, contact your Perkins dealer or
Perkins distributor.

Engines With a Coolant Recovery
Tank
Note: The cooling system may not have been
provided by Perkins. The procedure that follows is for
typical cooling systems. Refer to the OEM
information for the correct procedures.
Check the coolant level when the engine is stopped
and cool.
NOTICE
When any servicing or repair of the engine cooling
system is performed, the procedure must be per-
formed with the engine on level ground. This will al-
low you to accurately check the coolant level. This
will also help in avoiding the risk of introducing an air
lock into the coolant system.
