17 00 008 Draining and adding coolant in radiator (S63): Notes

WARNING: This page is about a different car, the 2013 BMW X5 M, 2012 BMW X5 M, 2011 BMW X5 M, and 2010 BMW X5 M. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required: 

WARNING: Risk of scalding!
Only carry out repair work on the cooling system after the engine 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 part quantities of coolant, replace these quantities which have been drained with new coolant.

Installation note: 

Use only recommended coolant. Observe mixture ratio. See RADIATOR - OPERATING FLUIDS
