Drain the coolant from the high-temperature cooling system

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.

Preliminary work 

NOTE: TECHNICAL INFORMATION 
Follow NOTES  for repair work on the cooling system. For additional information see:
Main group 17
(17 00) Notes for repair work on the cooling system
NOTE: TECHNICAL INFORMATION 
Filling without the vacuum filling equipment (watering can filling) is not permitted.
If this is not observed, there is a risk of component damage or engine damage.
The filling specification must be observed.
It is essential to visually check the vacuum filling equipment before use to check that it is functioning correctly and clean.
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise there may be functional limitations (degradation) or overheating.
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 
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 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
WARNING: Hot surfaces.
Risk of burning! 
  • Perform all work only on components that have cooled down.
