Effectivity: 582 UL
Edition 3 / Rev. 0
50 % antifreeze concentrate with additives against corrosion
and
50 % pure water, or use of an equivalent premixed coolant.
Obey the operating media manufacturer's instructions!
Satisfactory results were achieved with "BASF Glysantin Anti-
corrosion". Use this or an equivalent coolant.
NOTE
If problems are encountered with boiling coolant after engine
stop, increase percentage of antifreeze gradually.
In all cases, antifreeze to water ratios should not exceed the
antifreeze manufacturer's recommendations. Exceeding the
antifreeze manufacturers recommended ratios can lead to the
formation of particulates in the coolant solution or inadequate
protection against freezing.
Particulate formation may be harmful to cooling system com-
ponents and may restrict coolant flow to and from overflow
NOTE
At verification of the coolant level replenish coolant at radiator
cap (radiator or expansion tank). The coolant level in the over-
flow bottle should be between min. and max. mark.
