Remove the coolant expansion tank for the low-temperature coolant circuit (charge air cooler)
Prerequisite
- Ignition is switched off.
NOTE:
RISK OF DAMAGE
Careless handling of tools and sharp-edged components.
Scratches, surface damage.

- Protect working area.
- 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 last up to 11 min. This protects the components. In this case, replacing the electric fan will not remedy the problem!

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.
