Preparation of the coolant
CAUTION
Danger of engine damage from incorrect radiator protection
fluid concentration.
A too low radiator protection fluid concentration increases the
risk of corrosion and also the risk of the cooling system freezing.
A radiator protection fluid proportion of over 50 vol% degrades
the cooling action and also the protection against frost is re-
duced. Therefore, serious engine damage may result from ex-
ceeding or dropping below the radiator protection fluid concen-
tration.
▪ The radiator protection fluid must be prepared according to manufacturer's
instructions before pouring it into the cooling circuit. Comply with the infor-
mation on the packaging label.
▪ If the radiator protection fluid has to be mixed with water, use only clean
water that is not too hard. Tap water with as low as possible content of
salt, minerals, and suspended matter is ideal. Distilled water is equally ide-
al.
The coolant mixture ratio is not to be below or exceed the following concen-
tration:
Radiator protection
fluid
Water Frost-resistant to ap-
prox.
min. 40 vol% 60 vol% -27 °C
max. 50 vol% 50 vol% -38 °C
NOTICE
i
As the corrosion and antifreeze concentration reduces with time,
carry out an annual check with a commercially available anti-
freeze tester. If the concentration is too low, change the coolant
independent of the service interval (see the chapter 8.2.15
Changing coolant, page 82).
