Theoretically, as long as water does not submerge the air intake, the engine will not be affected. However, there are too many unpredictable factors, such as waves created by passing vehicles that could splash into the air intake, or unknown underwater conditions like potholes, which may affect the vehicle's passability. If a car drives through deep water without stalling, it indicates that the air intake was not flooded. Below are precautions for driving in rainy conditions: 1. Reduce speed: Regardless of road width or condition, drive slowly in the rain, always observing the distance to vehicles ahead and behind, and be prepared to take emergency measures. Visibility is poor in the rain, and the vehicle's braking distance and emergency performance are reduced, so slow down in advance to allow enough time and space to handle situations safely. 2. Maintain distance: Poor visibility in the rain necessitates keeping a safe distance from other vehicles, especially large trucks, which can block your view and create waves that smaller vehicles may not handle well. 3. Use fog lights: Utilize fog lights to enhance safety in rainy conditions, and turn on hazard warning lights if necessary to alert following vehicles to your presence. 4. Do not restart after stalling: In heavy rain or storms, some areas may flood quickly. If you must drive through water, do so at a steady speed in a low gear. If the vehicle stalls, do not attempt to restart it immediately, as this could severely damage the engine. Instead, contact a professional repair service to inspect the vehicle before restarting.
