Solutions for BYD F3 False High Water Temperature Reading
2 Answers
For a false high reading on the BYD F3 water temperature gauge, first check if the engine coolant level is low, which could cause the engine temperature to rise. Examine the circulation of the coolant to see if there's any blockage in the flow. Additionally, inspect the water temperature sensor and water pump. The thermostat and cooling fan could also be potential causes of high water temperature.
Recently, my BYD F3 has been experiencing frequent false high-temperature issues with the coolant, making driving quite nerve-wracking. Once, while stuck in city traffic, the coolant temperature suddenly shot up to 100 degrees Celsius. I immediately turned off the AC, pulled over, and popped the hood to check. The radiator shell was scorching hot, and the coolant reservoir was nearly empty. Later, I found out it was due to a coolant leak. After refilling it, the situation improved somewhat. I’d advise fellow car owners to keep a close eye on the temperature gauge—anything above 90 degrees should raise a red flag. Cooling system issues are quite common, such as radiator blockages or fan failures. I’ve had my radiator cleaned and a new water pump installed by a mechanic, which cost me around 200 RMB. Preventive maintenance is crucial—check the coolant level and radiator cleanliness every six months to avoid costly repairs. In short, don’t take it lightly; overheating can severely damage the engine’s core components.
