Note  
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.
