To the liquid does not freeze at -25 ?° C in it must be 40% low-freezing additives. To the liquid does not freeze at -35 ?° C the concentrate and water ratio should be 1: 1.
As the concentrate used G11 VW antizamerzayuschee or other means from the specification TL-VW774B (indicated on the package). The table shows how many need to add antizamerzayuschego means to ensure the concentration of the coolant does not freeze at -25 ?° C.
