10.5.14 Refill cooling water

– Use a water and antifreeze mixture to refill.
– Do not mix different antifreeze types.
– Use only soft water for the water and antifreeze mix-
ture.
– Only top up coolant when the engine is cool.
 Remove the right engine panel.
If the cooling water reservoir is completely empty, first fill
up the radiator:
1 Radiator lid
2 Drain screw
 Unscrew the radiator cap.
 Fill the radiator slowly all the way to the top without bub-
bles.
 Screw on the radiator lid.
Fill the cooling water equalising reservoir:
 Remove the lid of the equalising reservoir.
 Fill the equalising reservoir to the bottom mark.
 Close the lid for the equalising reservoir.
 Start the engine and let it warm up.
 Check the filling level in the coolant expansion tank.
While the engine is warm, the cooling water level must
be at the top mark.
 If the cooling water level is too low, shut the engine off,
let it cool off and fill the missing cooling water volume
into the cooling water equalising reservoir.

10.5.15 Check the water separator

1 Locking tap
2 Union joint
3 Container
