Coolant, Draining
WARNING!
Stop the
engine and let it cool before starting work on
the cooling system. Hot fluids and hot surfaces can
cause burns.
WARNING!
All coolant is hazardous and harmful to the
environment. Do not consume. Coolant is flammable.
Drain the coolant via taps (F).
1 Remove the filling cap (1) from the expansion
tank.
2 Connect a hose to each drain point. Open the
taps and allow all the coolant to drain off into a
suitable vessel.
Check that all coolant really does drain out.
Deposits may need to be cleared away, inside
the drain plug(s)/tap(s).
3
Also drain the heating system, tap water heater
etc., if connected to the engine’s freshwater sys-
tem.
4 Close all drain taps.
5 Collect the old coolant and hand it to a re-cycling
station for destruction.
Freshwater system, Flushing
The cooling system should be flushed when the cool-
ant is changed, to avoid loss of cooling performance
due to deposits in the cooling system.
1 Drain the coolant, please refer to Coolant, Drain-
ing page
97.
2 Put a hose into the filling hole in the heat exchanger
and flush with fresh water.
3 Flush until the water which runs out of the drain
points is clean.
4 Close all drain points when all coolant has run out.
5 Fill up with coolant, please refer to Mainte-
nance page 95.
