17 00 008 Draining and topping up coolant for high-temperature circuit: Notes

WARNING: This page is about a different car, the 2018 BMW 340i, 2017 BMW 340i, and 2016 BMW 340i. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Hot fluids.
Risk of scalding!
  • Conduct all work in the vehicle wearing appropriate personal protective equipment only.
CAUTION: Materials harmful to health.
Contact with fluids harmful to health!
  • Note and follow safety instructions on containers.
  • Conduct all work in appropriate personal protective equipment only.
NOTE: TECHNICAL INFORMATION
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
NOTE: TECHNICAL INFORMATION
Immobilization period-long fill of coolant! 
Do not 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 emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.
NOTE: TECHNICAL INFORMATION
Filling without  the vacuum filling equipment (watering can filling) is not permitted  .
Failure to observe this rule runs the risk of component damage/engine damage.
Filling specification absolutely must  be adhered to.
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise functional limitations (degradation) and/or overheating may result.
A bleeding procedure is required after a part has been exchanged in the cooling system and/or after refilling the cooling system.
NOTE: TECHNICAL INFORMATION
Follow NOTES FOR REPAIR WORK ON THE COOLING SYSTEM .
