Will water entering the car's air intake affect the engine?

[VincentLee]

Yes, it will have an impact. A small amount of water may enter the engine and mix with the engine oil, degrading the oil quality. Oil containing water can increase wear on engine components, potentially leading to increased engine noise and vibration during future driving. Below are precautions for driving through water: 1. Drive in a low gear: Use a low gear (for automatic transmission vehicles, engage the hill-climbing gear) and slowly drive through the water at a steady speed while maintaining control of the steering wheel. Be aware of any potholes or gaps beneath the water on the road. 2. Do not restart the engine after stalling: If the vehicle stalls in a waterlogged area, do not attempt to restart the engine. Engine stalling indicates that water has already entered the cylinders. Restarting the engine can cause severe damage due to the incompressibility of water, potentially bending or breaking the piston connecting rod components and, in severe cases, leading to complete engine failure.
