Maintenance: Freshwater system

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 minimum cooling water level on a cold engine is
175 mm [from the bottom of the sight glass and up
(A)].

The cooling water level of a cold engine must never
reach higher than 5 mm below the top of the sight
glass (B). For coolant specification refer to chapter
“technical data”.

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. coolers, water
heater, etc.

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 “coolant
level check”. Fill slowly letting air bleed from the
ventilation cocks and the filler opening. When air-
free coolant flows out, close the ventilation cocks.

4. To bleed the system, open all air vent cocks and

crank the engine for 10 seconds while holding the
emergency stop lever in stop position. Repeat se-
veral times at one minute intervals.
