Coolant, Draining
WARNING!
Do not open the coolant filler cap when the engine is
hot, except in emergencies, as this could cause
serious personal injury. Steam or hot fluid could spray
out.
IMPORTANT:
The coolant contains corrosion-inhibiting additives.
Never drain the engine cooling system on engines,
which are to be put in storage.
1 Stop the engine.
2 Remove the filler cap (1). Do not open the pressure
cap (2).
3 Place a suitable vessel for the coolant to drain off
into.
4 Open all drain points. Drain the coolant from the
radiator and engine block, using the drain hose.
The drain nipples are situated under the radiator on
the right side of the engine block.
5 Check that all coolant drains out. Deposits may be
found inside the drain plug/tap, and need to be
cleared away. There is otherwise a risk that coolant
could remain and cause damage due to freezing.
Check whether the installation has any further taps
or plugs at the lowest points of the cooling water
pipes.
6 Shut any taps and check that the spring-loaded
covers on the nipples close completely. Install the
rubber plugs.

Cleaning
IMPORTANT:
Do not use a high pressure power washer.

brush. Be careful not to damage the radiator vanes.
