Flush the Cooling System
● ALWAYS allow radiator to cool before
removing the radiator cap. The radiator will be
hot and can cause burns. When the radiator
cap is removed, pressure build-up in the
cooling system can cause the coolant to spray
out explosively.
● ALWAYS shut the engine down and allow it to
cool.
● NEVER remove the radiator cap before the
radiator and the engine are sufficiently cool
such that they can be touched with bare hands.
●
Loosen the radiator cap carefully to the first
stop, allowing excessive pressure to escape.
Only then remove the radiator cap. If the tractor
is equipped with a coolant reserve tank, add
coolant or water to the reserve tank, not to the
radiator. (See “Check the Cooling System” on
page 14-11).
1. Drain the Cooling System
1. Park the tractor safely and securely.
2. Allow the engine to cool off.
3. Open the hood.
4. Carefully open the radiator cap to the first to
release all the pressure.
