17 00 008 Draining and adding coolant (S55)

Special tools required: 

WARNING: Risk of scalding!
The repair work 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 part quantities of coolant, replace these quantities which have been drained with new coolant.

Installation note: 

Use only recommended coolant: Frostox HT-12 antifreeze/corrosion inhibitor, BMW part number 83 19 2 468 442

Observe the appropriate water/antifreeze mixture ratio.

Protective measures/rules of conduct:

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!
IMPORTANT: 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 00 2 030 (universal hydraulic lifting equipment).

Recycling: 

Observe country-specific waste disposal regulations.
