Is it normal for the temperature gauge to show 5 bars?

[McClayton]

It is not normal; 2 to 4 bars are considered normal. If the car's water temperature is too high, it can lead to poor engine cooling and excessive temperature. The expansion of components will reduce the clearance between parts, and the viscosity of the engine oil will decrease at high temperatures, accelerating wear on various components. If not addressed immediately, the engine may suffer severe damage due to overheating. Additional information: 1. Car temperature gauge: The car temperature gauge is marked with the letters "C" and "H" or uses white and red zones to indicate temperature. "C" stands for "cool," while "H" stands for "hot." The water temperature refers to the coolant temperature, and after the engine warms up, a normal reading is usually between 70-90°C. 2. How the temperature gauge works: The sensor of the temperature gauge is a thermistor-type sensor, fixed with threads to the engine's cooling water passage. The thermistor determines the current flowing through the coil of the temperature gauge, which drives the needle to move accordingly.
