G11 antifreeze

G11

— a simple class for low-cost-friendly antifreeze brands. As a basis, such coolants use a mixture of water and ethylene glycol with the inclusion of a small package of anti-corrosion additives of organic or inorganic origin. In modern engines, G11 antifreeze is rarely used, it is mainly used in cars with a cast-iron cylinder block. The pay for the G11's low price is the short lifespan of this class of coolant.
