Remove the coolant expansion tank for the low-temperature coolant circuit
WARNING:
Hot surfaces.
Risk of burning!
Risk of burning!
- Perform all work only on components that have cooled down.
NOTE:
RISK OF DAMAGE
Careless handling of tools and sharp-edged components.
Scratches, surface damage.

- Handle tools and components carefully.
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 take up to 11 minutes. This protects the components. In this case, replacing the electric fan is not necessary.

NOTE:
TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
The coolant must be replaced when replacing and removing components which depend on the anti-corrosion effect of 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.
