The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% coolant additive G12evo (TL 744-
L).
The proportion of coolant additive must always be at least 40% to protect the cooling system. If greater frost protection is required in
very cold climates, the proportion of anti-freeze additive can be increased. However, the percentage of coolant additive should not
exceed 55 %, as this would reduce the frost protection and the cooling effect.
The coolant additive is dyed a violet colour. The mixture of water and a coolant additive offers anti-freeze protection down to around
-25°C (around -13°F), protects the alloy parts in the cooling system against corrosion, prevents limescale deposits and significantly
increases the boiling point of the coolant.
When refilling the coolant, a mixture of distilled water and at least 40% of the coolant additive G12evo must be used in order to obtain
the optimum corrosion protection →
.
NOTICE
The colour of the coolant results from mixing the violet coolant additive with distilled water. If the liquid in the coolant expansion
tank is not violet but brown, for example, the suitable coolant has been mixed with another unsuitable coolant. This can result in
serious malfunctions or damage to the drive and cooling system.
● Use only coolant additives that have been approved by the manufacturer.
● Have the coolant replaced immediately by a suitably qualified workshop if it has a brown colour. Volkswagen recommends using an
authorised Volkswagen repairer.
● When adding coolant additives, never mix genuine coolant additives with other coolant additives that have not been approved by
Volkswagen.
NOTICE
The coolant must always have the correct mixture ratio. If the mixing ratio is not correct, serious malfunctions or damage to the drive
and cooling system may result.
● Have the correct mixing ratio checked by a suitably qualified workshop and restored if necessary if there is any doubt about the
mixing ratio. Volkswagen recommends using an authorised Volkswagen repairer.
