Mixing ratio
| Anti-freeze protection to | Coolant additive G 012 A8 D | Water |
|---|---|---|
| 25 ° C (-13 ° F) | Approx. 40% | Approx. 60% |
| 35 ° C (-31 ° F) | Approx. 50% | Approx. 50% |
| 40 ° C (-40 ° F) | Approx. 60% | Approx. 40% |
COOLANT MIXING RATIO
| CAUTION | If the fluid in the expansion tank is brown, G 012 A8 D was mixed with another coolant. In this case, rinse the coolant system and change the coolant. To rinse, fill the cooling system with clear water and let the engine run approx. 2 minutes. Coolant residues should be largely removed by this rinsing process. G012A8D and coolant additives with the note "according to TL VW 774 D" prevent frost and corrosion damage, lime deposits and also increase the boiling point of the coolant. For these reasons, the cooling system absolutely must be filled year-round with anti-freeze and anti-corrosion agents. The coolant contributes to operating safety during higher engine stress because of the higher boiling point, especially in tropical climates. The anti-freeze protection must be insured to about -25 ° C (-13 ° F) or in countries with an arctic climate, to about -35° C (-31° F). The concentration of anti-freeze must not be decreased during warm times of the year or in warm climates by topping off with water. The coolant additive percentage must be at least 40%. If for climatic reasons, greater anti-freeze protection is necessary, the percentage of G 012 A8 D can be increased, but only to about 60% anti-freeze protection (-40 ° C, or -40 ° F), otherwise the anti-freeze protection is reduced again and the cooling effect is impaired. |
