Cooling System, Top Up and Bleed
Caution
Only use Anti-freeze 19 40 656 (90 297 545) and ensure a
concentration of 50% water and 50% anti-freeze. The anti-freeze
does not only protect the entire cooling system from freezing, it
also protects all the components that the coolant has washed over
from rusting/calcium formation. Therefore, even in tropical
countries the anti-freeze agent must always be added.
The water quality also plays an important role in addition to
the mix ratio. Water of drinkable quality usually meets these
requirements. The quality of purified sea water is inadequate!
Damage may also be caused to the engine if unauthorised
anti-freeze agent is used.
If radiator, cylinder head or cylinder head seal have been
replaced the old coolant must not be re-used.

Add coolant up to "COLD" (1) marking on coolant compensation
tank.
After closing the cooling system, allow engine to warm up until
thermostat opens (coolant temperature approx. 80 °C).
Cooling system bleeds automatically during engine warm-up
phase.
Allow engine to cool down and check coolant, topping up coolant
to "COLD" marking on coolant compensation tank if necessary.
