What Causes the High Water Temperature in BYD Vehicles?

[StSawyer]

The reasons for high water temperature in BYD vehicles include: 1. Cooling fan not working: The cooling fan may be controlled by a temperature control switch or a water temperature sensor. 2. Radiator blockage: External blockages should be removed with water or air; internal blockages can affect coolant circulation and create pressure, leading to two possible outcomes—either radiator leakage or particularly high water temperature during high-speed driving. 3. Water pump failure: The impeller may slip or jam, causing the timing belt to break, or the impeller may become deformed. 4. Cylinder damage: Combustion chamber and water channel issues may cause water or white smoke to discharge from the drain pipe, leading to frequent radiator water shortage; water channel and oil channel issues (oil mixed with water turns white); water channel and water channel issues, resulting in poor cylinder heat dissipation, especially noticeable at high speeds; or water channel blockage.
