What are the reasons for high water temperature in BYD?
1 Answers
BYD high water temperature may be caused by: 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 can be removed with water or air; internal blockages affect coolant circulation and create pressure, leading to two possible outcomes—either radiator leakage or notably high water temperature during high-speed driving. 3. Water pump failure: Impeller slippage or jamming can cause the timing belt to break; impeller deformation. 4. Cylinder damage: Combustion chamber and water channel interference, leading to water or white smoke discharge from the exhaust pipe, causing frequent radiator water shortage; water and oil channel interference (engine oil turns white); water channel blockage, resulting in poor cylinder heat dissipation, especially noticeable at high speeds.
