Refill of empty system
NOTICE!
Mix the correct amount of coolant in advance
to ensure that the cooling system is completely filled.
Refer to
for the correct
coolant volume.
1 Check that all drain points are closed.
2 Only open the filler cap (1). Do not open the
pressure cap.
3 Fill with coolant, so that the level is between the MIN
and MAX marks. Fill slowly, to allow air to flow out.
4 Start the engine when the cooling system has been
completely filled and bled. Open any bleeding
nipples a short while after starting, to allow trapped
air to escape.
If a heating unit is connected to the engine cooling
system, the heat control valve should be opened
and the installation vented during filling.
5 Run the engine at idle a while. Increase engine
speed to 1600-1700 rpm over three minutes.
Check the coolant level.
6 Start the engine and run it until it reaches operating
temperature (thermostat open). Check the coolant
level again, top up as necessary.
7 Carry out a follow-up check of the coolant level after
approx 1 hour's operation.
