What is the best formula for antifreeze?
1 Answers
The antifreeze formula is a mixture of ethylene glycol + distilled water + additives (malonic acid, anti-corrosion and scale inhibitor, and triethanolamine), which constitutes the commonly used ethylene glycol water-based antifreeze. It prevents freezing in winter, boiling in summer, and can be used year-round while also offering anti-corrosion and anti-scale properties. More details are as follows: 1. During cold winter parking, it prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head. In the high temperatures of summer, it effectively prevents boiling, avoiding overheating issues. Automotive antifreeze plays a significant role, directly impacting the vehicle's performance and lifespan. Many people believe antifreeze is only used in winter, but in fact, it should be used throughout the year. 2. Antifreeze also has anti-corrosion properties. Since the engine's cooling system includes several metals such as steel, aluminum alloy, cast iron, copper, and solder used in radiator welding, the cylinder block and head are generally made of cast aluminum or cast iron, and the radiator is primarily made of copper and brass. Antifreeze must protect all these metals during long-term contact. Using deionized water and appropriate additives can prevent various types of corrosion.
