Specification of the engine coolant
The coolant additive prevents damage by frost and corrosion, prevents
lime deposits and also raises the boiling point of the water. For these rea-
sons, the cooling system must be filled with coolant additive the whole
year round.
Particularly in countries with a tropical climate, the coolant additive con-
tributes to operational safety by increasing the boiling point when the
engine is exposed to higher loads.
The cooling system must be filled with a mixture of water and coolant
additive
G 12
(observe information on the label) or an additive with the
specification TL-VW 774 D
.
The cooling system contains approx. 12 l coolant. The permanent filling of
the cooling system consists of 50% – but never more than 55% – coolant
agent
G 12
and provides frost protection up to -35 °C.
The water must have the following properties:
•
Total hardness
3 - 8 ° dH (German hardness)
•
ph value
7 - 8
•
Chlorine content
< 75 mg/l
Ask your local water authority for tap water specifications.
Unsuitable coolants include saltwater, rainwater, distilled water, water with
a high chloride content and fully demineralized water from ion exchang-
ers.
