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 hot 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 the side of the cylinder block (A1) or (B1) in order to drain the engine. 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. Where a lubricating oil
cooler/filter assembly is fitted, this must also be drained. To do this, disconnect the hose at the bottom of the
cooler (C1).
5 If necessary, flush the system with clean water.
6 Fit the hose to the bottom of the cooler.
7 Remove the hose at the top of the cooler (D) and put 165 ml (
1
/
3
pint) of antifreeze into the cooler. This will
give protection against frost if water drains down when the machine is moved.
8 Fit the hose to the top of the oil cooler.
9 Fit the drain plugs and the filler cap. Close the radiator tap or connect the radiator hose.
