Filling coolant
WARNING!
Burn hazard. Steam and hot fluid may spray out. Stop
the engine and allow it to cool before opening the filler
cap.
IMPORTANT!
Top up with the same type of coolant as already used
in the system. Different types of coolant must not be
mixed.
Topping up
Top up coolant to the correct level through the filler
opening on the expansion tank. Top up slowly, to allow
air that is displaced to flow out through the filler open-
ing.
When filling an empty system, or if the coolant level for
some reason has sunk sow low that it cannot be seen
through the filler opening, filling must be carried out
according to “Filling a completely empty cooling sys-
tem”.
Filling a completely empty cooling system
1 Mix a sufficient quantity of coolant in a vessel before
filling. Note that if a heating system, water heater or
such is connected to the engine cooling system, a
correspondingly greater quantity of coolant will be
required.
2 Ensure that any heating system, water heater or
such connected to the engine cooling system is
purged (open the heater regulator valve).
3 Fill coolant through the filler opening in the expan-
sion tank.
Fill slowly, to allow air that is displaced to flow out
through the filler opening.
4 Fill with coolant to approx. 5 cm (2“) below the filler
cap sealing surface.
5 Start the engine and let it idle for about 1 hour.
IMPORTANT!
Do not start the engine until the system is purged
and completely filled.
6 Stop the engine and let it cool. Check coolant level.
Top up as needed.
