What is the normal range for a car's coolant temperature gauge?
1 Answers
Generally, the coolant temperature of a regular household car during normal operation is around 95 degrees Celsius, while some high-performance cars or vehicles with higher thermal efficiency may operate at around 110 degrees Celsius. Cars with higher operating temperatures include BMW models, whose engines can even exceed 110 degrees Celsius under normal working conditions. The vehicle's cooling system is not solely designed for heat dissipation but to help the engine maintain an optimal operating temperature range. Many drivers pay close attention to coolant temperature, and some car dashboards are equipped with a coolant temperature gauge. However, besides coolant temperature, oil temperature is equally important. Excessively high oil temperature can cause the oil to thin, leading to oil film rupture, which results in engine wear. Conversely, if the oil temperature is too low, the oil becomes too viscous, preventing it from adequately lubricating the necessary components. Therefore, oil temperature is also crucial. When driving, it's advisable to avoid prolonged high-speed operation, as this can cause the oil film to rupture, leading to abnormal engine wear. Engine oil also plays a role in heat dissipation. If the engine is low on oil, it can easily overheat, potentially causing cylinder scoring.
