[DiAlexandra]

Audi A4 windshield washer fluid warning light comes on indicating that the coolant temperature is too high or the fluid level is too low. In this case, you should not continue driving, as there is a risk of engine damage. Coolant temperature too high: Due to the special construction of the car engine, it is prone to overheating during operation. Once the coolant temperature exceeds the normal range, the engine cannot dissipate heat properly, leading to overheating and affecting the engine's normal operation. The main causes of abnormal cooling system operation include: thermostat failure, radiator failure, fan not rotating, or clogged radiator. Engine function: The engine converts the thermal energy of gasoline into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. The car engine is the device that provides power to the car, acting as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental performance.
