What are the functions of automotive antifreeze?
2 Answers
Automotive antifreeze serves the following purposes: It protects the normal and optimal operation of the engine. The engine coolant circulates within the engine's fuel tank, providing anti-freeze, anti-rust, and anti-corrosion effects. It also prevents the car from freezing, which could cause the radiator to crack or damage engine components due to freezing. Engine coolant primarily consists of substances like ethylene glycol aqueous solution, among others. Many additives are incorporated into the coolant to protect various types of engines. Coolant is an indispensable medium for ensuring the proper heat dissipation and operation of a car's engine. If the engine lacks antifreeze, it can lead to the engine's temperature failing to decrease, resulting in severe malfunctions such as cylinder scuffing.
The role of car antifreeze is more than you think. It's not just for preventing freezing in winter; it also prevents the engine from overheating and boiling in summer because its boiling point is much higher than water. Additionally, it provides anti-corrosion protection, safeguarding the metal components of the engine from rust and extending the vehicle's lifespan. Its anti-scaling function is also crucial, reducing scale buildup in the pipes and preventing the cooling system from clogging. Lubricating the water pump is another minor benefit, ensuring smoother water flow and reducing wear. Last time I changed the antifreeze, I clearly felt the engine running more smoothly. Proper maintenance can save a lot on repair costs. When choosing antifreeze, pay attention to the freezing point and color. Regular checks and top-ups are also important, with a general recommendation to replace it every two years. Remember, using the right antifreeze ensures both safety and savings.
