Note

In vehicles as of model year 2008, only G 12 plus-plus ac‐

cording to TL VW 774 G may be used as coolant additive.

For vehicles up to and including model year 2007 coolant ad‐

ditive G 12 plus according to TL VW 774 F and G 12 plus-plus

according to TL VW 774 G can be used.

The coolant additive G 12 plus-plus can be mixed with the

previous coolant additive G 12 plus. Identification: Both are

coloured purple.

Coolant additives marked “according to TL VW 774 G” or “ac‐

cording to TL VW 774 F” prevent frost and corrosion damage,

scaling and also raise boiling point of coolant. Therefore, the

cooling system must be filled all year round with coolant ad‐

ditive and corrosion protection additive.

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 coolant additive can be increased, but only up to 60

% (frost protection to about -40 °C). Otherwise frost protection

and cooling effectiveness are reduced again.

The refractometer -T10007- is recommended for determining

the current anti-freeze concentration.

If radiator, heat exchanger, cylinder head or cylinder head

gasket is renewed, do not reuse old coolant.
