How to drain the cooling system

Caution: Do not drain the coolant while the engine is still hot and the system is under pressure because
dangerous coolant can be discharged.
1 Ensure that the machine is on level ground.
2 Remove the filler cap of the cooling system.
3 Remove the drain plug from either side of the cylinder block (A) in order to drain the engine.
Note: Ensure that the drain hole is not restricted.
4 Open the tap or remove the drain plug at the bottom of the radiator in order to drain the radiator. If the radiator
does not have a tap or drain plug, disconnect the hose at the bottom of the radiator.
5 If a lubricating oil cooler is fitted, open the drain tap or remove the drain plug (B1 or C1/D1/E1/F1) in order
to drain the coolant from the oil cooler.
