17 00 008 Draining and adding coolant (N54)
Special tools required:
- 00 2 030
See MAINTENANCE AND GENERAL INFORMATION - SPECIAL TOOLS .
WARNING:
Danger of scalding!
These tasks on the cooling system should only be carried out on an engine that has cooled down!
These tasks on the cooling system should only be carried out on an engine that has cooled down!
IMPORTANT:
Lifetime coolant filling:
Never 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 drained and refilled.
In the case of other removal work involving the draining of partial quantities of coolant, replace these quantities which have been drained with new coolant.
