Removing coolant expansion tank for high-temperature coolant circuit

WARNING: Hot surfaces. 
Risk of burning! 
  • Perform all work only on components that have cooled down.
WARNING: Hot fluids. 
Risk of scalding! 
  • Conduct all work in the vehicle wearing appropriate personal protective equipment only.
WARNING: Vehicle may slip off the vehicle hoist if the vehicle hoist is handled incorrectly. 
Danger! Immobilization period-threatening injuries! 
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 
Notes on work at the cooling system form the basis of these repair instructions and must be complied with at all times.
For additional information see: 17 00... INSTRUCTIONS FOR REPAIR WORK ON COOLING SYSTEM
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
