What is the Water Temperature Gauge?

[JocelynRose]

Automobile water temperature gauges are marked with the letters C and H, or use white and red zones for differentiation. C stands for Cold, and H stands for Hot. If the water 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. Normal Range: The water temperature gauge is normal as long as it is within the normal scale range. The pointer entering the red zone indicates that the water temperature is too high. Prolonged high water temperature can lead to boiling, meaning the engine coolant boils, which can cause the radiator to burst and the engine to overheat and be damaged. How to Lower Water Temperature: Use the coolant (antifreeze) specified by the manufacturer. Do not simply add water to the radiator. During traffic jams, the engine generates heat, and the radiator relies solely on the fan for cooling, resulting in poor cooling efficiency, causing the water temperature to gradually rise. Once the vehicle starts moving, the flowing air aids in cooling, improving the cooling efficiency, and the water temperature will naturally decrease.
