Maintenance. Freshwater system
Coolant level. Inspection
Note.
Coolant level can be checked through a level
glass on top of the expansion tank.
The green float must be visible in the level glass.
WARNING!
Never open the pressure cap
when the engine is hot. Steam or hot coolant
can spray out at the same time as the pressure
which has built up is lost.
The coolant level should be about five centimetres (”)
below the pressure cap sealing plane in the expansion
tank.
If a separate expansion tank is installed, the coolant
level must be between the MAX and MIN markings.
Top up the coolant as necessary, following the de-
scription below.
Coolant. Filling
WARNING!
Stop the engine and let it cool be-
fore filling. Hot fluids and hot surfaces can cause
burns.
IMPORTANT! Top up with the same type of
coolant as already used in the system.
Topping up
Fill up with coolant to the correct level via the filling hole
on the expansion tank. Fill slowly, to allow the air which
is forced out a chance to flow out of the filling hole.
When you fill up an empty system, or if the coolant
has fallen so low for any reason that it is no longer
visible through the filling hole, fill up as in the de-
scription for “Filling a completely empty system”.
Filling a completely empty system
1. Mix a sufficient quantity of coolant in a vessel be-
fore filling. Please note that a heating system, tap
water heater etc. if connected to the engine cool-
ing system, mean that a correspondingly greater
amount of coolant will be needed.
. Open the vent tap by the turbocharger.
3. Also ensure that the heating system, tap water
heater etc. if connected to the engine cooling
system, are also vented (open the heater control
valve).
