Maintenance: Freshwater system
Coolant level. Check
WARNING! Never open the pressure cap when
the engine is warm. Steam or hot fluid may spurt
out.
The level of the coolant should be approx. 5 cm (2 in.)
below the top of the filler pipe. If an external expan-
sion tank is used the level should be between the MIN
and MAX marks on its side. Top up when necessary
according to the description below.
IMPORTANT! Check the coolant level on a cold
stationary engine.
Coolant. Filling
WARNING! Stop the engine and allow it to cool
down before filling. Hot fluids and hot surfaces
can cause burns.
IMPORTANT! Use the same type of coolant that
is already in the system.
Topping up
Fill with coolant to the correct level through the filler
opening on the expansion tank. Fill slowly so that the
evacuated air is able to pass through the filler open-
ing.
If the heat exchanger is empty, the coolant must
be filled according to the description "Filling the
cooling system when empty".
Filling the system when empty
1. Open the ventilation cocks by the turbocharger and
the heat exchanger.
2. Make sure any other systems such as heater, wa-
ter heater, etc., connected to the cooling system
are also ventilated.
3. Fill with coolant through the filler opening on the
expansion tank.
4. Fill slowly so that the evacuated air is able to pass
through the ventilation cocks and the filler opening.
5. When the coolant is free of air bubbles, close the
ventilation cocks.
