Only perform work on the engine cooling system if you are familiar with the necessary activities and the general safety
precautions, and if the correct operating equipment, fluids and suitable tools are available. Work performed incorrectly can
result in serious injuries ⇒
. Have all work performed by suitably qualified professionals if necessary. Volkswagen
recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Information about warning and indicator lights can be found in the troubleshooting section at the end of the chapter
⇒ Troubleshooting.
WARNING
Engine coolant is poisonous. Contact with coolant, especially swallowing coolant, may result in serious or fatal injuries.
If you swallow coolant, seek urgent medical help.
If you have health problems after working with coolant, seek medical help.
Always store engine coolant out of the reach of children and only within the sealed original container.
Never use empty food cans, bottles, or other containers to store engine coolant, because someone could drink the
engine coolant by mistake.
Avoid regular contact with coolant to prevent damage to your skin.
Protect your skin, face, and particularly your eyes when working with coolant.
Do not eat, drink, or smoke when working with coolant.
Wash your skin with soap and water after working with coolant.
WARNING
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.
Coolant and coolant additives can pollute the environment. Catch any leaking operating fluids and dispose of them
correctly according to environmental regulations.
Engine coolant specifications
Please read the introductory information and heed the Warnings and Notice ⇒
Safety precautions for working in the
engine compartment.
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 engine cooling system. 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 approx. -25 °C (approx. -13 °F), protects the light-alloy parts in the cooling system against corrosion,
prevents calcium deposits and significantly 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 mus
