The G12evo coolant standard is currently the latest standard among VW coolants. As the successor to the G13 coolant, the original VW G12evo has been used and recommended in various VW models since 2018 – more precisely since 06/2018. In addition to the standard by name, the G12evo also hides the VW release VW TL-774-L.
Looking at the chemical composition of this coolant, presents a so-called HOAT technology (abbreviation for “Hybrid Organic Acid Technology”). This coolant consists of phosphates, silicates and organic additives. The silicate acts as a corrosion inhibitor. HOAT technology was already used in the VW G13 and VW G12++ coolants, which also improved their miscibility.
