Antifreeze plays a crucial role in vehicle performance and longevity. High-quality antifreeze not only prevents freezing but also has a boiling point higher than water’s 100°C; it also inhibits rust, scale formation, and corrosion. Therefore, even in summer, ordinary water should never be used as a substitute for antifreeze.

Antifreeze typically comes with a warranty period, usually two years (though some products offer longer warranties). Therefore, it must be replaced regularly—generally every two years or every 40,000 kilometers of driving. So, as summer approaches, what should we pay attention to when choosing and using antifreeze?

Pay attention to the product’s freezing point?

As the name suggests, the primary function of antifreeze is to prevent freezing. This can be assessed by examining the product’s “freezing point” value: the lower the freezing point, the better the antifreeze performance in extremely low-temperature conditions. Anyone with a background in chemistry understands what a freezing point is; therefore, the lower the freezing point, the more effective the product will be at preventing freeze damage in harsh cold environments. Consumers should select an appropriate antifreeze based on the climate in their region—ideally, the freezing point of the antifreeze coolant should be about 10°C lower than the local minimum temperature—to ensure that the antifreeze remains effective even during extreme weather events.

Comprehensive rust and corrosion protection?

Engine cooling systems are made from a variety of materials, including aluminum, copper, iron, steel, zinc, rubber, and plastics, and are designed to last for more than ten years. Yet many vehicles still experience leaks and coolant seepage—problems that are almost always caused by substandard or counterfeit antifreeze. High-quality antifreeze provides comprehensive protection for all these materials, effectively preventing such issues from occurring. Therefore, antifreeze should never be added haphazardly; it is essential to choose products that are backed by a quality guarantee.

Can water replace antifreeze coolant?

Using water instead of antifreeze does pose certain risks. For short-term emergency use, adding water is acceptable and will not immediately damage the thermostat or clog the cooling passages; however, long-term use is not recommended.

Can different types of antifreeze be mixed?

When replacing the antifreeze, it is best to use the same brand and model; mixing different brands is not recommended. If you do switch to a different brand of antifreeze coolant, be sure to drain the existing coolant from the engine, thoroughly flush all cooling passages, and then refill.

How to choose a good antifreeze product?

Golden Globe antifreeze possesses all the characteristics of nationally standardized antifreeze: it provides long-lasting protection against rust and cavitation, prevents scale, sludge, and foaming, does not corrode gaskets or sleeves, and contains inhibitors that remain active over the long term, ensuring high performance even under severe operating conditions. This environmentally friendly, long-life product protects the engine, cylinder liners, and radiator, while preventing deposit formation, cavitation, and corrosion.
