Drain the coolant from the low-temperature cooling system
Prerequisite
- Switch off ignition.
Preliminary work
- Refer to REMOVE RESONATOR .
- Refer to REMOVE THE FRONT UNDERBODY PROTECTION OR FRONT THRUST FIELD .
- Refer to REMOVING THE UNDERBODY PROTECTION OF THE STEERING GEAR AND THRUST FIELD RESPECTIVELY .
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.
