WARNING: This page is about a different car, the 2011 BMW M3, 2010 BMW M3, 2009 BMW M3, and 2008 BMW M3. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Risk of scalding!
Only carry out repair work on the cooling system after the engine has cooled down!
Risk of skidding due to coolant on the floor.

Risk of skidding due to coolant on the floor.
Protective measures/rules of conduct
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
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.

IMPORTANT:
For dirt contamination of the cooling system (e.g. by engine oil), the cooling system must be rinsed with water until all dirt contamination is removed!

Risk of skidding due to coolant on the floor.
Danger of injury!
Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 002030 DEVICE (universal hydraulic lifting equipment).
Recycling
Observe country-specific waste disposal regulations.
Necessary preliminary work
Draining coolant
Open sealing cap (1) on coolant expansion tank (2).
If fitted, release drain connector (1) on coolant radiator.
On coolant radiators which do not have a drain connector, remove coolant hose.
Drain, catch and dispose of coolant from radiator.
Installation note:
Replace sealing ring.
