Why does the BYD F3 have high water temperature when the air conditioning is on?

[DiEmersyn]

First, check if the engine's high water temperature is caused by insufficient antifreeze. Also, inspect the circulation of the coolant to see if there is poor circulation. Additionally, you can examine components such as the water temperature sensor, water pump, thermostat, and cooling fan, as these can also lead to high water temperature. Here is some relevant information: 1. Reasons for falsely high water temperature in BYD F3: High-speed operation of the electric fan; long service life of the radiator; insufficient coolant; clogged radiator. 2. Water temperature sensor: The interior of the car's water temperature sensor is a thermistor, where the lower the temperature, the higher the resistance, and vice versa. It is installed on the water jacket of the engine block or cylinder head, in direct contact with the cooling water, to measure the temperature of the engine's cooling water.
