Refilling/Bleeding the cooling system
The cooling system must be bled as described below after draining the
cooling liquid or after adding more than 0.25 l (0.06 US gallons) cooling
liquid.
Make sure that the drain screw
1 is fastened.
Pour approx. 0.5 litres (0.13 US gallons) coolant into the system.
Remove screw
2 at the cylinder head. Reinstall it as soon as the cooling
liquid emerges free of air bubbles (only for 125/200 engines).
Remove the screw
3 on the right radiator.
Now add cooling liquid until it emerges free of bubbles at the right radia-
tor. Then immediately mount the screw so that no more air can enter the
right radiator.
Top up the left radiator until the coolant can be seen approx. 10 mm
(0.4 in) above the radiator fins.
Check the coolant level again after a short ride.
