Note! | t
| Only use antifreeze additive G 12 according to specification TL -VW 774 F-. Identification: purple colour. |
| t
| The purple G 12 (in accordance with standard TL -VW 774 F-) may be mixed with the previous used red G 12 antifreeze additive. |
| t
| On no account must G 12 be mixed with other anti-freeze additives. |
| t
| If the fluid in expansion tank is brown, G 12 has been mixed with other anti-freeze additives. In this case the coolant must be changed. |
| t
| G 12 and anti-freeze additives marked ”In accordance with TL -VW 774- D” prevent frost and corrosion damage, scaling and also raise boiling point of coolant. For this reason the system must be filled all year round with anti-freeze and corrosion protection additives. |
| t
| Because of its high boiling point, the coolant improves engine reliability under heavy workloads, particularly in countries with tropical climates. |
| t
| The anti-freeze protection should be guaranteed to approx. -25 °C (in countries with arctic weather up to approx. -35 °C). |
| t
| Coolant concentration must not be reduced by adding water, even in warmer seasons or in warmer countries. The percentage of anti-freeze additive should be at least 40%. |
| t
| If for climatic reasons a greater frost protection is required, the amount of G 12 can be increased, but only up to 60 % (frost protection to about -40 °C) With a greater concentration engine cooling and anti-freeze properties are diminished. |
| t
| If radiator, heat exchanger, cylinder head or cylinder head gasket has been replaced, do not reuse old coolant. |
