♦
Use only coolant additive G12 plus in accordance with
„TL VW 774 F“. Identification: purple colour.
♦
G 12 plus and coolant additives marked „Conforming to
TL VW 774 F“ prevent frost and corrosion damage and scaling
and also raise boiling point of coolant. Therefore, the cooling
system must be filled all year round with frost and corrosion
protection additives.
♦
Because of its higher boiling point, the coolant improves en‐
gine reliability under heavy loads, particularly in countries with
tropical climates.
♦
Frost protection is required down to about -25°C (in countries
with arctic climates: down to about -35°C).
♦
The coolant concentration must not be reduced by adding wa‐
ter even in warmer seasons and in warmer countries. The
coolant additive concentration must be at least 40%.
♦
If for climatic reasons greater frost protection is required, the
amount of G 12 can be increased, but only up to 60 % (frost
protection to about -40 °C). Otherwise frost protection and
cooling effectiveness are reduced again.
♦
If radiator, heat exchanger, cylinder head or cylinder head
gasket is renewed, do not reuse old coolant.
♦
The Refractometer -T10007- is recommended for determining
the current anti-freeze density.
Recommended mixture ratios:
