8.11.2 Changing the coolant
Perform this maintenance work at the latest after
two years.
Do not start the engine after draining off the coolant.
In case of lubrication oil entering into the cooling system or a suspi-
cious turbidity caused by corrosion residues or other suspended
matter, the coolant must be drained off and the complete cooling
system needs to be cleaned.
Oil can damage the sealing materials used in the cooling system.
If oil has entered, you must add a cleansing agent in order to
remove any residues from the system. Follow the instructions of
the manufacturer! If in doubt, consult your Customer Service or the
engine manufacturer.
When changing the coolant without any signs of contamination,
cleaning of the cooling system is not necessary.
