■Servicing the Cooling System

Avoid injury.
●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 “Checking
the Cooling System” on page 14-11).

1. Draining the Cooling System

1. Park the tractor safely.
2. Allow the engine to cool off.
3. Raise the hood.
4. Remove the side panel from the right side of the
engine.
5. Carefully open the radiator cap to the first to stop to
release all the pressure.
6. Tightly close the radiator cap.
7. Open the radiator petcock. Drain the coolant into a
drain pan.
8. Put a drain pan below the drain plug at the right side of
the engine. Allow all the coolant to drain.
9. To promote draining of the coolant from the reserve
tank, remove the radiator cap.
