Instruction. All engines are filled with G012 A8 D concentrate according to TL -VW 774 D-. Only G 12 concentrate should be topped up (Red). Never use G Oil A8 C. Concentrates G 011 A8 C and G 012 A8 D must not be mixed. Mixing them can cause serious engine damage.
Check coolant level, top up if necessary
Check the coolant level in the expansion tank when the engine is cold.
Inspection service
The coolant level is between the min and max marks. If the coolant level is below normal, add the missing amount, mixing in the appropriate proportions.
Mixing ratio
Frost protection up to | Coolant additive G 012 AZ D | Water |
-25°С | about 40% | about 60% |
-35°C | about 50% | approximately 50% |
-40°С | approximately 60% | about 40% |
Instruction. If the liquid in the tank turned brown, then the G012 A8 D additive was mixed with another coolant. In this case, flush the cooling system and replace the coolant. To flush the cooling system, fill it with clean water and let the engine run for about 2 minutes. As a result of flushing, coolant residues must be completely removed. G 012 A8 D and concentrates marked "according to cTL-VW 774-D" prevent freezing of the coolant and the formation of corrosion and scale. In addition, they increase the boiling point of the coolant. For these reasons, it is mandatory to fill the cooling system with antifreeze and corrosion protection throughout the year. Especially in countries with a tropical climate, the coolant contributes to the reliable operation of the vehicle due to a higher boiling point with increased engine load. The freezing point of the coolant must be at least -25°C (in countries with an arctic climate - not less than -35°С). The coolant concentration must not be lowered by topping up with water, also in warm seasons or in countries with warm climates. The share of coolant should be at least 40%. If, due to climatic conditions, enhanced frost protection is required, then the proportion of G012 A8 D can be increased, but not more than up to 60% (freezing point approx. up to -40°C), because otherwise the frost protection is weakened again and, in addition, the cooling effect is impaired.
Checking antifreeze, if necessary, adding coolant additive
If the freezing point of the filled coolant is too low, it is necessary to drain part of it and add concentrate G 012 A8 D in accordance with TL -VW 774 D- instead.

After a test drive, check the concentration of the coolant additive.
