J635000 Cooling System, Charge and Bleed (Z 22 SE)
Caution
Only use Anti-freeze 19 40 650 / 09 194 431 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.
