Adding VW Concentrate to the Cooling System

In order for the liquid not to freeze at -25°C, it must contain 40% low-freezing additives. In order for the liquid not to freeze at -35°C, the ratio of concentrate and water should be 1:1.

As a concentrate, use G11 VW or other anti-freeze agent from specification TL-VW774B (indicated on the packaging). The table shows how much anti-freeze agent must be added to ensure that the coolant concentration does not freeze at -25°C.

Quantitative difference in liters	3,5	3,0	2,0	1,5

Example

Measurement with a hydrometer shows that the coolant does not freeze at -10°C. In this case, drain 2 liters of liquid from the cooling system and add 2 liters of pure VW antifreeze concentrate to the cooling system.

Close the radiator cap and after the control run, check the tightness again.
