What Causes the Water Temperature Warning Light to Illuminate While Driving?
1 Answers
The reason the water temperature warning light illuminates while driving is: the water temperature is too high. The car's water temperature gauge indicates whether the engine's cooling system is functioning properly, and it consists of a pointer, scale, and the letters 'C' and 'H'. The function of the car's water temperature gauge is to display the temperature of the coolant in the engine's water jacket during operation, with the scale unit in degrees Celsius. When the engine starts, the water temperature gauge should indicate no less than 50 degrees Celsius, and during normal driving, the normal reading should be between 70 and 90 degrees Celsius. If the water temperature is too high, the water temperature warning light will illuminate. The water temperature indicator light is used to alert the temperature of the coolant inside the engine, displaying different effects by color: blue indicates low water temperature, red indicates high water temperature, and no light indicates normal conditions.
