Cooling System, Top Up and Bleed
Caution
Only use 19 40 656 (90 297 545) anti-freeze and ensure a
concentration of 50% water and 50% anti-freeze. The purpose of
anti-freeze is not only to protect the entire cooling system
against freezing but also to protect all coolant-affected parts
against corrosion and lime deposit. For this reason, even in
tropical regions, anti-freeze must be used.
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.

Top up coolant (1) to "KALT" (cold) mark on coolant compensation
tank.
After closing the cooling system, let engine run warm until
thermostat opens (coolant temperature approx. 92 °C / 194
°F).
Allow engine to cool and check coolant level. If necessary, top
up coolant to mark "Kalt" (cold) in coolant compensation tank.
Note: Cooling system
bleeds automatically during engine warm-up phase.
