Remove the radiator of the high-temperature coolant circuit

NOTE: TECHNICAL INFORMATION 
When the engine is stopped after the completion of trip, it may be necessary to run the electric fan. In rare cases, operation of the electric fan can last up to 11 min. This protects the components. In this case, replacing the electric fan will not remedy the problem!

Preliminary work 

WARNING: Hot surfaces. 
Risk of burning! 
  • Perform all work only on components that have cooled down.
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 
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 
Follow notes for repair work on the cooling system.
For additional information see: NOTES FOR WORKING ON THE COOLING SYSTEM .
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
