What is the function of Radiator Coolant?
2 Answers
Radiator Coolant functions: Helps prevent automobile engine overheating, providing summer anti-boiling, winter antifreeze, year-round anti-corrosion, anti-scale, anti-rust, and anti-foaming effects. It offers protection for cast iron parts, brass, copper, aluminum alloy, solder, and rubber components. It is also compatible with any antifreeze or cooling water. Radiator Coolant: The difference between Radiator Coolant and antifreeze lies in their freezing points. Radiator Coolant is an additive primarily used in antifreeze coolant to clean scale deposits in the radiator and cylinder block. Antifreeze: Antifreeze is added to the radiator to provide antifreeze and heat dissipation functions. Although their compositions are largely similar with minimal efficacy differences, Radiator Coolant has a higher freezing point than antifreeze, making it more prone to freezing when used alone. Therefore, using antifreeze is more recommended.
I've been driving for over a decade, and coolant has been a great help. It's mainly added to the cooling system to prevent freezing in winter and boiling in summer, protecting the engine from freeze damage or overheating. This stuff is much better than tap water—it doesn't leave scale deposits in the pipes and also prevents rust and corrosion on metal parts. Last winter when I was on a business trip to Northeast China, my car was parked outside overnight at temperatures below -20°C. Thanks to the antifreeze coolant, the engine didn't freeze. For regular maintenance, it's recommended to replace it every two years, making sure to choose the correct type by color, as mixing different types can cause reactions. Oh, and remember to check the coolant level regularly and top it up when low—otherwise, uncontrolled engine temperature can cause serious trouble.
