Drain the coolant from the low-temperature cooling system
WARNING:
Hot surfaces.
Risk of burning!
Risk of burning!
- Perform all work only on components that have cooled down.
CAUTION:
Overheating of the high-voltage system.
Risk of fire! Injury hazard!
Risk of fire! Injury hazard!
- If the low-temperature coolant circuit is empty, de-energize the high voltage system.
- Drain the coolant only when the high-voltage system has been de-energized.
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.
