WARNING: Danger of scalding! 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: Aluminium-magnesium materials.
No steel screws/bolts may be used due to the threat of electrochemical corrosion.
A magnesium crankcase requires aluminium screws/bolts exclusively.
Aluminium screws/bolts must be replaced each time they are released.
The end faces of aluminium screws/bolts are painted blue for the purposes of reliable identification Jointing torque and angle of rotation must be observed without fail (risk of damage).
Necessary preliminary tasks:
- Remove coolant thermostat
Unfasten hose clip (1).
For tightening torque refer to 11 53 5AZ.
Remove coolant hose.
Unfasten hose clip (2).
