The antifreeze reservoir has markings, including an upper limit and a lower limit indicated by letters. As long as the antifreeze level is within this range, it is acceptable. Here is some related information: 1. Antifreeze refers to antifreeze coolant, which is used to cool the engine and has functions such as preventing freezing, scaling, and corrosion. Windshield washer fluid is a cleaning agent for washing the windshield, with the main purpose of cleaning the glass. To prevent the windshield washer reservoir from freezing in winter, there is also antifreeze windshield washer fluid. 2. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze can prevent the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head.
