centration and the condition
of the coolant
!
Danger
Danger of scalding!
Check the anti-freeze concentration only when
the engine is cold.
!
Caution
In order to avoid damage to the engine (e.g. by
corrosion, cavitation and freezing), particular
attention must be paid to the inspection of the
coolant.
For quality and quantity of coolant refer to the
"table of fuels and lubricants".
Do not mix different coolants and additives,
see section "Fuelds and Lubricants - Coolant".
In case of lubrication oil entering into the cool-
ing system or a suspicious turbidity caused by
corrosion residues or other suspended matter,
the coolant must be drained off and the com-
plete cooling system needs to be cleaned. Lu-
brication oil can damage the sealing materials
used in the engine.
Environment
Catch coolant and dispose of environmentally.

be at least 35 Vol% and maximum 45 Vol%.
l
Check the condition of the coolant.

If the coolant is contaminated by corrosion res-
idues or other suspended matter, flush the
cooling system, see section "Changing the
coolant".
