Volkswagen ID.4: Engine coolant specifications

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).

To protect the engine cooling system, there must always be at least a 40% proportion of coolant additive. If greater freeze protection is needed due to the climate, the proportion of coolant additive can be increased. However, the proportion of coolant additive must not exceed 55 %, because otherwise the freeze protection will be reduced and the cooling effect will be decreased.

The engine coolant additive can be recognized by its violet color. The mixture of water and coolant additive provides freeze protection down to -25 ºC (-13 ºF), protects the aluminum alloy parts of the cooling system from corrosion, prevents limescale deposits, and increases the boiling point of the coolant.

If the engine coolant is being topped up, a blend of distilled water and at least 40% of the G12evo engine coolant additive must be used to ensure optimum corrosion protection → .

CAUTION

In extremely low temperatures, the coolant can freeze and the vehicle could break down. This can cause the heating to stop working in the vehicle. Vehicle occupants could die of exposure if they do not have sufficient warm clothing.

• Make sure the coolant additive is always adjusted according to the ambient temperature.
• Only use coolant additive approved by the manufacturer.

NOTICE

The coloring of the engine coolant results from the mixture of the purple coolant additive and distilled water. If the fluid in the coolant expansion tank is not purple, but for example brown, the engine coolant has been mixed with another non-suitable coolant. Serious malfunctions or damage to the electric drivetrain and cooling system could occur.

• Only use coolant additive approved by the manufacturer.
• If the coolant turns brown, have it changed immediately by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
• Never mix original Volkswagen coolant additives with coolant additives that are not approved by Volkswagen when topping up.

Engine coolant and coolant additives can harm the environment. Catch any leaking operating fluids and dispose of them correctly according to environmental regulations.
