Is green or orange coolant better?

The choice between green and orange antifreeze depends on the specific needs of the vehicle. Its freezing point is usually around -30°C, and the recommended replacement interval is 2 years or 40,000 kilometres. Orange antifreeze, on the other hand, is primarily used in high-end or high-performance vehicles. Its formula demonstrates superior anti-corrosion properties and high-temperature resistance, meeting the cooling demands of turbocharged engines or extreme operating conditions. However, it comes at a relatively higher price, and the replacement interval may extend to 5 years or longer. It is crucial to note that the two antifreeze types have different chemical compositions; mixing them is strictly prohibited as it may lead to cooling system malfunctions. Vehicle owners are advised to select the appropriate antifreeze based on the manufacturer's recommendations in the vehicle manual or professional technician's guidance to ensure optimal engine cooling system performance and longevity.
