Can I drive when the water temperature gauge shows 0°C at startup?

You can drive, but it is recommended to warm up the engine for a few minutes, as this is not the ideal temperature for optimal fuel efficiency. Reasons for using a water temperature gauge: An automobile engine requires a certain operating temperature for normal functioning. Temperatures that are too high or too low are not conducive to the engine's normal operation and performance. On the other hand, the heat generated by the engine cannot be sufficiently dissipated by conventional air cooling alone, which is why water cooling systems are widely used in automotive engines. The cooling system's role is to maintain the engine within the most favorable temperature range to enhance engine power, reduce wear, and minimize fuel consumption. Both excessively high and low temperatures can adversely affect engine performance. Normal water temperature gauge readings: The water temperature gauge typically ranges from 0 to 130°C, with the normal operating temperature centered at 90°C. After starting the vehicle, the water temperature rises quickly. Once the needle reaches the center position, the temperature stabilizes. Generally, it is best to start driving when the temperature reaches the middle position.
