How to Read the Vehicle Temperature Gauge?

[LaBentley]

Automobile water temperature gauges are marked with the two English letters "C" and "H", or distinguished by white and red zones. "C" is the first letter of the English word "cool", meaning cold. "H" is the first letter of the English word "hot", meaning heat. Relevant information about the automobile water temperature gauge is as follows: Introduction: The water temperature refers to the temperature of the coolant. After the engine warms up, it generally displays 70-90 degrees as normal. When the water in the cooling tank is low, the water temperature will rise, and it is necessary to add water at this time. If the temperature gauge approaches the "H" or the red danger zone, and in severe cases, the water temperature warning light comes on, it indicates that the engine coolant temperature is too high. Working Principle of the Water Temperature Gauge: The sensor of the water temperature gauge is a thermistor-type sensor. It is fixed with threads on the engine cooling water passage. The thermistor determines the magnitude of the current flowing through the coil winding of the water temperature gauge.
