How many bars on the car temperature gauge are normal?

[OMary]

The normal range for the car temperature gauge is 2-4 bars, which corresponds to a temperature between 90-110 degrees Celsius. Normal water temperature: The water temperature refers to the temperature of the coolant. After the engine warms up, it typically displays 70-90 degrees as normal. When the coolant level in the radiator is low, the water temperature will rise, and it's necessary to add water. If the temperature gauge approaches the 'H' mark or the red danger zone, and in severe cases, the temperature warning light comes on, it indicates that the engine coolant temperature is too high. Working principle: The temperature gauge sensor is a thermistor-type sensor, which is fixed with threads to the engine coolant passage. The thermistor determines the current flowing through the coil windings of the temperature gauge, thereby driving the movement of the gauge needle.
