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 Extended Life Coolant
(ELC). Refer to this Operation and Maintenance
Manual, “Refill Capacities” topic (Maintenance
Section) for more information on cooling system
specifications. Do not install the cooling system
filler cap. Maintain the coolant level between the
marks on the header tank. Refer to this Operation
and Maintenance Manual, Coolant Level - Check
for more information.
2.
Start and run the engine with no load. Operate the
engine to open the engine thermostat. An open
thermostat 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 between the marks on
the header tank, refer to this Operation and
Maintenance Manual, Coolant Level - Check for
more information.
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, 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 proper operating temperature.

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.
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 proce-
dure will allow you to check accurately the coolant
level. This procedure will also help in avoiding the risk
of introducing an air lock into the coolant system.
1.
Remove the cooling system filler cap (1) slowly to
relieve pressure.
