Why is the Water Temperature Gauge Not Moving?

[SanMalachi]

Water Temperature Gauge Not Moving is caused by a faulty water temperature sensor, and it is recommended that the owner replace the water temperature sensor. Car engines are water-cooled, and this type of engine relies on coolant circulating continuously within the engine to remove excess heat. There are two circulation paths for the coolant inside the engine: one is the large circulation, and the other is the small circulation. When the engine is first started and has not yet reached normal operating temperature, the coolant circulates in a small loop within the engine. Knowledge about car water temperature: Under normal circumstances, the pointer on the car's water temperature gauge will change as the water temperature changes. When the vehicle is first started, the water temperature is generally low, especially in winter, and it is advisable to warm up the car first. The purpose of warming up the car after starting is ultimately to check whether the water temperature is normal.
