17 00 008 Draining and adding coolant (N54)
This repair work on the cooling system should only be carried out on an engine that has cooled down!
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.
Installation note:
Use only recommended coolant. See COOLING SYSTEM - OPERATING FLUIDS .
Observe mixture ratio .
