4. Clean the cooling system filler cap. Inspect cooling
system filler cap gasket. If the cooling system filler
cap gasket is damaged, discard the old cooling
system filler cap and install a new cooling system
filler cap. If the cooling system filler cap gasket
that is on is not damaged, use a suitable
pressurizing pump 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.
5. Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.

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.
1. Observe the coolant level in the coolant recovery
tank. Maintain the coolant level to "COLD FULL"
mark on the coolant recovery tank.
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
2. Loosen filler cap slowly in order to relieve any
pressure. Remove the filler cap.
3. Pour the correct coolant mixture into the tank.
Refer to the Operation and Maintenance Manual,
"Refill Capacities and Recommendations" for
information on the correct mixture and type of
coolant. Refer to the Operation and Maintenance
Manual, "Refill Capacities and Recommendations"
for the cooling system capacity. Do not fill the
coolant recovery tank above "COLD FULL" mark.

4. Clean filler cap and the receptacle. Reinstall the
filler cap and inspect the cooling system for leaks.
Note: The coolant will expand as the coolant heats
up during normal engine operation. The additional
volume will be forced into the coolant recovery tank
during engine operation. When the engine is stopped
and cool, the coolant will return to the engine.
Engines Without a Coolant
Recovery Tank
Check the coolant level when the engine is stopped
and cool.
