Maintenance
Coolant. Checking and filling
WARNING!
Do not open the filler cap when the
engine is hot, except in emergencies. Steam or
hot fluid could spray out.
Check the coolant level daily before starting. Top the
coolant up as necessary.
The level should be about 50 mm below the sealing
plane of the filler cap, or between the MIN and MAX
markings, if a separate expansion tank is installed.
IMPORTANT!
Topping up should be done with
the same type of mixture as is already in the
cooling system; refer to “Coolant, mixing”.
Filling a completely empty system
Filling should be done with the engine stopped. Fill up
slowly, to allow the air to flow out. The system is
vented automatically.
Fill up with coolant to the correct level.
Do not start
the engine until the system is vented and com-
pletely filled.
Start the engine and warm it up until the thermostats
are open, about 20 minutes. Open any venting taps
some while after starting, to allow trapped air to es-
cape. Check the coolant level and top up as neces-
sary.
NOTE!
If a heating unit is connected to the engine
cooling system, the heat control valve should be
opened and the installation vented during filling.
