Remove the coolant expansion tank for the low-temperature coolant circuit

NOTE: DANGER 
High-voltage system. 
The high-voltage system operates on the basis of hazardous, electrical voltage and high currents. Mortal hazard through electric shock! 

Preliminary work 

WARNING: Hot surfaces. 
Risk of burning! 
  • Perform all work only on components that have cooled down.
NOTE: TECHNICAL INFORMATION 
Use commercially available pinch-off tools to pinch off the coolant hoses.
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.
