Maintenance: Freshwater system
Checking the coolant level
MS engines
Make sure the level is between the MIN and MAX
marks. If there are no marks, the coolant level
should be approximately 5 cm below the top of the
filler cap. For coolant specification, refer to chapter
“technical data” in the back of this manual.
MT engines
The cooling water level (A) should be approximately
5mm below the top of the side glass on a cold engi-
ne.
Filling the coolant
Topping up
Fill the freshwater system with coolant to the correct
level through the filler opening in the expansion tank.
For correct coolant level, refer to section “coolant le-
vel check”. Fill slowly so that the evacuated air is able
to pass the filler opening.
Filling when the system is empty
1. Open the air ventilation cocks and close the coo-
lant drain cocks.
2. Make sure that systems connected to the cooling
system also are ventilated, e.g. heater, water
heater.
3. Fill the freshwater system with coolant to the cor-
rect level through the filler opening in the expansi-
on tank. For correct level, refer to section “Check-
ing the coolant level”. Fill slowly letting air bleed
from the ventilation cocks and the filler opening.
When air-free coolant flows out, close the ventila-
tion cocks.
4. To bleed the system, open the air vent cock on
the water pump and crank the engine for 10 se-
conds while holding the emergency stop lever in
stop position. Repeat several times at one minute
intervals.
5. Close the air vent. Check the coolant level and
top up if needed.
