What are the differences between antifreeze and coolant?
1 Answers
The difference between antifreeze and coolant is that antifreeze only has antifreeze function, while coolant has both cooling and antifreeze functions. The full name of coolant is antifreeze coolant, which is a coolant with antifreeze function. Correct use of coolant can not only protect the engine's cooling system to improve heat dissipation, but also enhance engine efficiency and extend its service life. The following are the functions of antifreeze coolant: 1. Anti-corrosion function. The engine and its cooling system are made of metals such as copper, iron, aluminum, steel, and solder. These metals will corrode and rust when in contact with water under high temperatures over time. Antifreeze coolant not only does not cause corrosion to the engine cooling system, but also has anti-corrosion and rust removal functions. 2. Antifreeze coolant has a high boiling point. The boiling point of water is 100°C, while the boiling point of high-quality antifreeze coolant is usually above 110°C, making it less likely to boil when used in summer. 3. Antifreeze coolant can prevent scale. The most troublesome issue for drivers using water as a coolant is scale formation. Scale adheres to the metal surfaces of the radiator and water jacket, gradually reducing heat dissipation efficiency and being difficult to remove. High-quality coolant is made with distilled water and contains scale inhibitors, not only preventing scale formation but also having descaling functions.
