If the car didn't stall when passing through water, does it definitely mean there's no problem with the engine?

Since the engine didn't stall, it means there was no impact on the engine. Only automatic stalling and breakdown would have an effect. Here is some relevant information: 1. Wet systems or short circuits: Generally not a big issue. You can start the car after the circuits dry naturally or use a hair dryer to dry them. In severe cases, you may need to replace the fuse. 2. Water entering the exhaust pipe or air intake: If it's confirmed that water has entered the exhaust or intake, the car must be towed to a repair shop for inspection. Do not attempt to start the engine forcefully, as this could cause greater damage due to ineffective engine lubrication. 3. Consequences of passing through deep water: Passing through deep water can generally cause wire short circuits, poor contact, water entering the engine, rusting of the car body, and mold in fabrics and sound insulation layers.
The car didn't stall while driving through water, which is indeed a good sign, indicating the engine is still functioning properly. However, this absolutely doesn't mean it's 100% safe. Having driven for several years, I know water entering the intake system, wire connectors, or chassis components can cause problems, such as corroding metal or short-circuiting electronic parts. Afterward, symptoms like engine shaking, increased fuel consumption, or warning lights are common. It's best to promptly check if the air filter is soaked, whether the exhaust pipe is blocked, and especially the position of the electronic control unit, as many cars have it hidden in low areas prone to moisture. When wading through water, I always control the speed and avoid rushing to prevent water from splashing in.
