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 the boiling point of coolant. For this reason, the system must be filled all year round with anti-freeze and anti-corrosive additives. |
| t
| Because of its high boiling point, coolant improves engine reliability under heavy work loads, particularly in countries with tropical climates. |
| t
| 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 anti-freeze additive/coolant ratio must 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
| The tester -T10007- is recommended for determining antifreeze density. |
| t
| If radiator, heat exchanger, cylinder head or cylinder head gasket has been replaced, do not reuse old coolant. |
