What is the normal temperature for coolant?

[DeAlex]

Coolant at 90 degrees is normal. Coolant prevents the freezing of the liquid in cold winter conditions, which could otherwise crack the radiator and damage the engine cylinder block. Its full name is antifreeze coolant. Many people think that coolant is only used in winter, but in fact, it should be used all year round. Coolant is a type of cooling liquid with special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as antifreeze in winter, anti-boiling in summer, and anti-scale and anti-corrosion throughout the year. There are many types of automotive coolants, such as calcium chloride from inorganic substances, methanol, ethanol, ethylene glycol, glycerin, lubricating oil from organic substances, and common substances like sugar and honey from daily life, all of which can serve as the base liquid for antifreeze. After adding an appropriate amount of purified soft water, it becomes the general antifreeze coolant.
