Volkswagen Touran Owners Manual: Coolant specification

First read and observe the introductory information and safety warnings

The engine coolant system is factory-filled with a mixture of specially prepared water and at least 40 percent of the coolant additive G 12 plus-plus (TL-VW 774 G) or G 12 plus (TL-VW 774 F). Both coolant additives are dyed purple.

This mixture gives the necessary frost protection down to -25 °C (-13 °F) and protects the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and raises the boiling point of the coolant.

The proportion of the coolant additive must, in order to protect the coolant system, always be at least 40 %, even if anti-freeze is not required in warm weather and warm climates.

If greater frost protection is required in very cold climates, the proportion of the anti-freeze additive can be increased. However, the percentage of coolant additive should not exceed 60 %, as this would reduce the frost protection and the cooling effect.

When topping up coolant, you must use a mixture of distilled water and at least 40 % coolant additive - G 12 plus-plus - to obtain the optimum corrosion protection  .

WARNING

Insufficient anti-freeze in the coolant system can cause the engine to break down and cause serious injuries.

NOTICE

Never mix genuine coolant additives with other coolants that have not been approved by Volkswagen. Mixing other coolants could cause serious damage to the engine and cooling system.

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be collected and disposed of properly and with respect for the environment.
