What Causes a Car's Water Temperature to Be Too High?

[ColtonDella]

Car water temperature being too high is caused by: 1. Insufficient coolant: Prolonged water circulation during engine operation can lead to coolant loss in the engine's cooling system, resulting in insufficient water in the radiator; 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leaks, which then obstructs water circulation; 3. Cooling fan malfunction: A damaged cooling fan or a short circuit in the wiring can prevent the fan from operating or cause it to spin too slowly. The car's water temperature reflects the working condition of the cooling system. The engine must operate within an appropriate high-temperature range. When the engine coolant temperature is around 90 degrees, the engine reaches its optimal operating state. At this temperature, the combustion chamber is hot enough to fully evaporate the fuel, allowing for better fuel combustion and reduced gas emissions.
