NOTICE
Fill the cooling system no faster than 19 L (5 US gal)
per minute to avoid air locks.
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 °C to 66 °C
(120 °F to 150 °F).
5. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly to
relieve any pressure. Remove the cooling system
filler cap. Open the drain valve. Allow the water to
drain. Flush the cooling system with clean water.
Close the drain valve.

NOTICE
Fill the cooling system no faster than 19 L (5 US gal)
per minute to avoid air locks.
1. Fill the cooling system with Extended Life Coolant
(ELC). Refer to this Operation and Maintenance
Manual, "Fluid Recommendations" 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. Run the engine at high
idle for 1 minute to purge the air from the cavities
of the engine block. Stop the engine.
3. 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 within
13 mm (0.5 inch) to the proper level on the sight
glass.
4. Clean the cooling system filler cap. Inspect the
gasket that is on the cooling system filler cap. Only
install the used filler cap if the gasket is not
damaged. Test the cap for the correct pressure.
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 and Inspect the cooling system for
leaks and for proper operating temperature.
Cooling System Coolant Level
- Check
Check the coolant level when the engine is stopped
and cool.

Cooling system filler cap
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.
1. Remove the cooling system filler cap slowly to
relieve pressure.
2. Maintain the coolant level within 13 mm (0.5 inch)
of the bottom of the filler pipe. If the engine is
equipped with a sight glass, maintain the coolant
level to the proper level in the sight glass.
