What do C and H on the dashboard represent?

[BriellaLee]

The CH on the dashboard represents the water temperature gauge. The water temperature ranges from C to H. C stands for 60 degrees Celsius. Once the needle of the water temperature gauge reaches C, it indicates that the water temperature has reached 60 degrees. The red H mark represents a temperature of 110 degrees Celsius. The span from 60 to 110 degrees Celsius allows for an estimation of the temperature indicated by the water temperature gauge. Introduction to the water temperature gauge: Automobile water temperature gauges generally use a scale from 60 degrees Celsius to 120 degrees Celsius or are labeled with Cold (C) to Hot (H). The water temperature indicator light is used to show the temperature of the coolant inside the engine. Some indicators use colors to display different statuses: blue indicates the water temperature is too low, red indicates the water temperature is too high, and no light indicates normal operation. When a car engine is running, the combustion of gasoline generates significant heat, with some being expelled through the exhaust pipe and some transferring to the engine block. If the engine block temperature becomes too high, it can cause thermal expansion of components and lead to damage. Therefore, water is used for circulating cooling. Hazards of excessively high or low water temperature: Hazards of low water temperature: It can cause incomplete combustion of the air-fuel mixture, reduce power output, increase fuel consumption, lead to poor lubrication, and result in excessive emissions. Hazards of high water temperature: Normally, when the water temperature is within the normal range, the needle will point to the middle position of the water temperature gauge (this may vary between different car models; it is recommended to check the warranty manual). However, there is usually a red zone on the right side of the water temperature gauge indicating the high-temperature range. When the needle approaches this zone, caution is required as it indicates the water temperature is too high. If no action is taken and driving continues, it can easily lead to the radiator boiling over.
