Note t
| Only use coolant additive G 12 in accordance with TL VW 774 F. Identification: purple colour. |
t
| G 12 and coolant additives marked in accordance with 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 frost and corrosion protection additives. |
t
| G 12 purple (in accordance with TL W 774 F) can be mixed with existing coolant additives G 11 and G 12 red! |
t
| Because of its higher boiling point, the coolant improves engine reliability under heavy loads, particularly in countries with tropical climates. |
t
| Frost protection is required down to about -25 °C (in countries with arctic climates: down to about -35 °C). |
t
| The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The coolant additive concentration must be at least 40 %. |
t
| 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. |
t
| The refractometer -T10007- is recommended for determining the current anti-freeze density. |
t
| If radiator, heat exchanger, cylinder head or cylinder head gasket is renewed, do not reuse old coolant. |
