Antifreeze Indicator?

[CamilleMarie]

The indicator for insufficient car antifreeze is a small sailboat-like symbol on the dashboard. Introduction to Antifreeze: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing in cold seasons, which could lead to radiator cracks and engine block freezing. A common misconception should be corrected: antifreeze is not only used in winter. In regular car maintenance, the engine antifreeze needs to be replaced annually during driving. Functions of Antifreeze: Antifreeze has multiple functions including antifreeze, anti-boil, anti-corrosion, and anti-scaling. Like water, it has advantages such as high specific heat, large latent heat of evaporation, and easy replenishment. When the ambient temperature drops below zero, water in the cooling system will turn into ice, posing a risk of expansion and cracking to cooling system components. The use of antifreeze ensures the normal operation of the engine in low temperatures.
