What are the main functions of antifreeze?

The main functions of antifreeze are: 1. Anti-corrosion; 2. High boiling point; 3. Prevention of scale buildup; 4. Freeze protection. The method for replacing antifreeze is: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the reservoir. The full name of antifreeze is antifreeze coolant, which is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It contains: calcium chloride, methanol, ethanol, ethylene glycol, glycerol, etc.
I've been driving for over a decade, and antifreeze is simply a lifesaver. It prevents freezing in winter, ensuring the cooling system doesn't crack in sub-zero temperatures, and prevents overheating in summer, keeping the engine stable during long highway drives. It also prevents internal corrosion and rust, protecting metal components like the radiator and engine. I remember once during a heavy snowstorm when I had to travel far – if I hadn't replaced the antifreeze beforehand, the cost to repair burst pipes would have been thousands. Using this fluid regularly extends the car's lifespan, reduces maintenance costs, and provides peace of mind. A single replacement lasts two years, it's affordable, and it lubricates the water pump for smooth operation in the cooling system – totally worth it.
