What is the normal temperature for car coolant?

Car coolant temperature is normal between 80 to 90 degrees Celsius. Coolant Temperature: Coolant temperature refers to the temperature of the antifreeze. Inside the engine, besides the oil passages, there are also antifreeze passages. The full name of antifreeze is antifreeze coolant, and its important functions are to cool and lower the engine temperature, as well as to prevent freezing in winter. Precautions: When the coolant temperature reaches 90 degrees, it indicates that the engine's heat generation has stabilized. Both excessively high and low coolant temperatures can damage the engine. Low temperatures are not conducive to engine lubrication, while high temperatures can lead to engine self-ignition. During daily driving, pay attention to the coolant temperature indicator on the dashboard. If the red light comes on, do not continue driving. It is recommended that the driver pull over to let the engine cool down.
