fault code code89 is a warning to the driver that the engine cooling system is low on antifreeze. Functions of antifreeze: In cold weather, it prevents components from system failures, cracks, and expansion due to cooling issues. It also manages rust prevention and prevents excessive scale buildup that could clog pipelines, offering anti-corrosion, anti-scale, anti-boiling, anti-freezing, and anti-rust properties. Main uses of antifreeze: Antifreeze, fully known as antifreeze coolant, is a coolant with antifreeze properties that prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Antifreeze is a specially formulated coolant primarily used in liquid-cooled engine cooling systems, with its freezing point varying according to the concentration of ethylene glycol in the solution.
