What is hoat antifreeze?

Hoat antifreeze, or "Hybrid Organic Acid Technology" antifreeze, is a type of coolant that combines traditional inorganic and modern organic acids to provide effective engine protection. It helps prevent overheating and freezing while also reducing corrosion in the cooling system. HOAT antifreeze is often used in European and some Asian vehicles, offering longer service intervals compared to conventional coolants. It's important to use the correct type of antifreeze specified by the vehicle manufacturer for optimal performance.
