Filling an empty system
NOTICE!
Mix the coolant in advance to ensure that the
cooling system is filled with the correct mixture,
(applies to concentrated coolant). Do not start the
engine until the system is completely filled.
NOTICE!
If a heating unit is connected to the engine
cooling system, the heat control valve for the system
must be opened and the installation vented during
filling.
•
Check that all drain points are closed.
•
Fill with coolant until the level is above the MIN mark
in the expansion tank.
•
When the cooling system is filled, start the engine
and let it idle for a few minutes.
•
Open any venting nipples for a while to allow
trapped air to escape.
•
Increase engine speed to 1600-1700 rpm and run
for a few more minutes.
•
Stop the engine and let it cool down. Then check the
coolant level.
•
Start the engine. Start the engine again and run it
until it reaches normal operating temperature (when
the thermostat opens). Allow to cool, and check the
coolant level.
NOTICE!
Do not drain the system if the engine is to be
in storage for a longer period of time. The coolant
contains corrosion protection additives.
