What are the reasons for high water temperature in BYD?

[Jade]

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.

That time when I was driving my BYD on a long trip and the water temperature alarm suddenly went off, my heart jumped into my throat. Checking the coolant level is the most common culprit, especially in older models prone to leaks that cause low levels. If the radiator fan gets stuck and stops spinning, the heat can't dissipate, causing the temperature to skyrocket. A faulty water pump can prevent coolant from circulating properly, leading to higher temperatures. The thermostat, that little gadget, getting stuck in the closed position can also cause overheating. Additionally, a clogged radiator or one covered in dust can reduce cooling efficiency. I’ve made it a habit to check the coolant every month—if it looks dark or has too many impurities, I replace it. Before long trips, it’s a must-check to prevent overheating and save on major repair costs.

As an enthusiast who loves tinkering with cars, I believe the main reasons for BYD's high water temperature lie in the cooling system. First, insufficient coolant levels, possibly caused by pipe leaks or natural evaporation, require regular replenishment of specialized coolant. Secondly, fan failure prevents operation, and sensor malfunctions prevent the fan from activating, leading to inadequate heat dissipation. A damaged water pump interrupts circulation, affecting cooling. The thermostat is a critical component; if it fails, it disrupts the water temperature balance. Other issues include radiator blockages and belt slack causing inefficiency. It is recommended that owners immediately slow down and stop the vehicle upon a water temperature warning, check related components to avoid engine damage, which is far more costly than replacing parts.

High engine temperature is no small matter, I've encountered several instances where BYD's dashboard warning lights turned red. The most common cause is insufficient coolant - always check if the reservoir level meets standards. If the cooling fan gets stuck or the motor fails, airflow stops and temperature rises immediately. A malfunctioning water pump prevents coolant circulation for heat dissipation. A faulty thermostat leads to heat accumulation. Also watch for leaks - address any coolant puddles under the car promptly. During routine maintenance, remember to clean the radiator to ensure proper ventilation. Driving with high engine temperature poses significant risks and may damage core engine components.

In my experience, BYD's high water temperature is often caused by simple issues. Insufficient coolant is the primary culprit, and topping it up usually solves the problem; a faulty cooling fan, such as deformed blades affecting rotation; a failed water pump interrupting fluid flow; or a stuck thermostat preventing heat dissipation. Additionally, a clogged radiator or loose belts can also contribute to overheating. Regular maintenance is key: check the cooling system for leaks monthly, and changing the antifreeze every two years can significantly reduce risks. If the water temperature spikes, don't push through—pull over, turn on the heater for ventilation to lower the temperature before addressing the issue.

Regarding the reasons for the rise in water temperature of BYD vehicles, I believe there are mainly three aspects. System issues: insufficient coolant or poor quality requiring replacement; water pump failure leading to poor circulation; radiator fan jammed or relay failure. Component problems: thermostat not functioning properly to regulate; radiator blocked by insect screens. Other factors such as prolonged high-load driving may cause temporary overheating. It is recommended that car owners regularly test the pH level of the coolant and maintain the fluid level within the standard range. If the water temperature remains consistently high, do not ignore it and visit a service center to prevent major repair costs.
