An effective coolant for vehicles should exhibit many crucial properties, including antifreeze for low temperatures, heat protection thanks to a high boiling point, corrosion protection for metallic components, protection against cavitation, compatibility with different materials in the cooling system, stable pH values to avoid residue, excellent thermal conductivity to ensure efficient cooling and a long service to prevent disproportionately frequent changes. These characteristics not only ensure that the engine is protected from overheating and corrosion, but also that the entire cooling system works efficiently over longer periods of time.
