Coolant is a mixture of water and at least 40% coolant additive.

The cooling system must be filled with a mixture of water and at least 40 % of our coolant additive G 12+ or an additive with the specification TT-VW 774 F (it is dyed purple). This mixture gives the necessary frost protection down to -25°C and protects the alloy parts of the cooling system against corrosion. It also prevents scaling and raises the boiling point of the coolant.

The concentration of coolant must always be at least 40% - even if frost protection is not required.

If greater frost protection is required in very cold climates, the proportion of the antifreeze additive G 12+ can be increased. However, the percentage of coolant additives should not exceed 60%, as this would reduce the frost protection. It would also reduce the cooling effect. A mixture with 60% coolant additive will give frost protection to approx. -40°C.

WARNING

• The coolant additive is toxic. There is a toxic risk. Always keep the coolant additive in the original container which should be stored out of the reach of children. The same applies to coolant that you have drained off.
• The coolant additive G 12+ must be added in sufficient quantities to provide anti-freeze protection at the coldest ambient temperatures that can be expected. At extremely cold ambient temperatures, the coolant could freeze, causing the vehicle to breakdown. As the heater would also not work in this situation, there is a risk of suffering exposure!

Caution
• Other additives may give considerably inferior corrosion protection. The resulting corrosion in the cooling system can lead to a loss of coolant, causing serious damage to the engine.
• The coolant additive G 12+ (purple) can be mixed with the additive G 12 (red) or G 11. Never mix G12 (red colour) with G 11.
