SEBU8732
NOTICE
Improper or incomplete rinsing of the cooling system
can result in damage to copper and other metal
components.
To avoid damage to the cooling system, make sure to
completely flush the cooling system with clear water.
Continue to flush the system until all signs of the
cleaning agent are gone.
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. Remove the connection hose or
remove the cooling system drain plugs. Allow the
water to drain. Flush the cooling system with clean
water. Install the connection hose.
6. The drain plug O rings on the engine block must be
replaced. Clean the drain plugs and install new O
ring seal. Install the drain plugs and tighten to a
torque of 35 N·m (25 lb ft).
Fill
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.
1. Fill the cooling system with the coolant/antifreeze.
Refer to this Operation and Maintenance Manual,
"Refill Capacities and Recommendations" topic
(Maintenance Section) for more information on
cooling system specifications. Do not install the
cooling system filler cap.
2. Start and run the engine at low idle. Increase the
engine rpm to high idle. Operate the engine in
order to open the engine thermostat. This
operation will allow any air in the system to be
purged. Decrease the engine speed to low idle.
Stop the engine.
3. Maintain the coolant level at the maximum mark
that is correct for your application.
Maintenance Recommendations
4. 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, perform a pressure test. If the cooling
system filler cap does not retain the correct
pressure, install a new cooling system filler cap.
5. Start the engine. Inspect the cooling system for
leaks and for the correct operating temperature.

NOTICE
Perkins ELC must be using with an extender in order
to achieve 12000 hours operation. For more informa-
tion on a suitable extender contact your Perkins deal-
er or Perkins distributor.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note: When the cooling system is cleaned, only
clean water is needed when the ELC is drained and
replaced.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. Replace the water pump, the water
temperature regulator, and the hoses, if necessary.
NOTICE
Service or repair of the engine cooling system must
be performed on level ground. The engine must be
level in order to check the coolant level. The engine
must be level in order to avoid the risk of introducing
an air lock into the coolant system.
