Can You Drive When the Water Temperature Gauge is Blue?

[Harvey]

You can drive when the water temperature gauge is blue. A blue water temperature gauge indicates that the water temperature is too low. If you drive for an extended period with the water temperature too low, the engine will not reach its normal operating temperature, leading to poor lubrication and significant wear on internal engine components. The role of the water temperature gauge: For a car engine to operate normally, it requires a specific working temperature. Neither too high nor too low is conducive to the engine's normal operation and performance. On the other hand, the heat generated by the engine cannot be sufficiently managed by conventional air cooling, which is why water cooling systems are widely used in car engines. The function of the cooling system is to maintain the engine within an optimal temperature range, thereby enhancing engine power, reducing wear, and minimizing fuel consumption.
