The manufacturer prohibits the use of water (even distilled) in the Octavia cooling system. The use of water is prohibited even in emergency situations.
The Cooling System of Octavia Tur holds 6-7 L antifreeze with labeling G-011 (G11). This antifreeze has a blue, green color. Replace antifreeze every 2 years.
It is considered that if the cooling system is anti-freeze with the markings G-012 (G12) red, it is not in need of replacement. However, it would also be better replaced after two years of operation. It is forbidden to mix antifreeze to G11 and G12.
