WARNING:
Risk of scalding.
Only perform this work after engine has cooled down.
Only perform this work after engine has cooled down.
Recycling:
Catch and dispose of drained coolant in a suitable container.
Observe country-specific waste disposal regulations.
IMPORTANT:
If a water pump that has already been operated is reused, it must be filled with coolant immediately after removal.
Mixture ratio, water: coolant = 1: 1
Protect plug connections against coolant and contamination.
Cover plug connections with suitable materials.

IMPORTANT:
Aluminum-magnesium materials
.
No steel screws/bolts may be used due to the threat of electrochemical corrosion.
A magnesium crankcase requires aluminum screws/bolts exclusively.
Aluminum screws/bolts must be replaced each time they are released .
Aluminum screws/bolts are permitted with and without color coding (blue).
For reliable identification:
Aluminum screws/bolts are not magnetic .
Joining torque and angle of rotation must be observed without fail (risk of damage) .

- Retaining elements on chassis and suspension and steering parts must be replaced.
Necessary preliminary work:
- Release ANTI-ROLL BAR .
- Drain COOLANT .

Remove electric coolant pump in downward direction.
Installation note:
Replace aluminum screws .
Installation note:
If the electric water pump is reused, it must be rotated one turn due to the breakaway torque at the blade wheels.
Assemble engine.
