Removing both coolant expansion tanks
Preliminary work
- Refer to REMOVING DESIGN COVER .
- Refer to REMOVING THE FRONT UNDERBODY PROTECTION .
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:
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.
