NOTE:
TECHNICAL INFORMATION
Filling without the vacuum filling equipment (watering can filling) is not permitted
If this is not observed, there is a risk of component damage or engine damage
The filling specification must be observed
It is essential to visually check the vacuum filling equipment before use to check that it is functioning correctly and clean
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise there may be functional limitations (degradation) or overheating
A bleeding procedure is required after a part has been exchanged in the cooling system and/or after refilling the cooling system

NOTE:
TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be emptied and refilled
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant
