Coolant at 110 degrees Celsius is normal. As long as the temperature does not exceed 120 degrees Celsius, it is considered normal. Coolant, fully known as antifreeze coolant or simply antifreeze, prevents the coolant from freezing and cracking the radiator or engine cylinder block during cold weather shutdowns. Antifreeze is not only used in winter but should be used year-round. In regular car maintenance, engine coolant should be replaced annually. Functions and roles of coolant: 1. Winter antifreeze: To prevent the coolant from freezing and causing the radiator and engine block to crack when the car is parked in winter, the freezing point of the coolant should be about 10°C lower than the lowest temperature in the region, preparing for sudden weather changes. 2. Anti-scaling: The coolant should minimize scale formation during circulation to avoid clogging the circulation pipes and impairing the coolant's heat dissipation function. In summary, selecting and adding coolant should be done carefully. First, choose a coolant with an appropriate ratio based on specific conditions. Second, add the selected coolant to the radiator until the liquid level reaches the specified position. 3. Anti-boiling: Coolant that meets national standards typically has a boiling point exceeding 105°C, higher than water's boiling point of 100°C, allowing the coolant to withstand higher temperatures without boiling (overheating), thus meeting the cooling needs of high-load engines to some extent.
