Is there any problem if a car passes through deep water without stalling?

There is basically no impact. Since water pressure is much lower than the exhaust pressure of the cylinders, as long as the vehicle does not stall, water will not flow back into the engine, so there will be no adverse effects. Relevant information about car engines is as follows: Introduction: A car engine is the device that provides power to a vehicle, serving as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems, among others.
The car drove through deep water without stalling, and I thought I was lucky at the time. But after driving home, I noticed the throttle was a bit sluggish. The mechanic found that water had entered the exhaust system and chassis, causing metal rust and wiring corrosion, which affected exhaust flow. Although the engine didn’t take in much water, water splashing onto electrical connectors could cause short circuits, and the spark plugs are also prone to moisture and aging. After driving through water, it’s best to immediately drive to dry ground, check if the air filter is damp, and clean the chassis to avoid rust. Prevention is key—slow down when encountering deep water to reduce splashing, avoid forcing your way through if the water exceeds the tire height, and regularly maintain and inspect the exhaust pipes and brake lines for peace of mind.
As a car enthusiast, if your engine didn't stall during water crossing, it means the air intake wasn't submerged, indicating lower risk. But that doesn't mean everything's fine. High water levels may invade the exhaust tailpipe or electrical components, causing sensor short-circuit failures. After wading, immediately find dry ground to check for water stains under the chassis. Replace the air filter if wet. Excessive water vapor entering the engine can cause lubrication deficiency and wear. Don't be careless when driving - avoid water deeper than wheel hubs. Regularly check engine oil and transmission fluid for emulsification or discoloration to prevent damage.
Driving through deep water without stalling the engine is good, but water seeping into components poses significant risks. Quickly move away from the waterlogged area and check the braking system, as water immersion can cause brake discs to rust and reduce performance. Water entering the exhaust port can lead to moisture corrosion of metal pipes, causing long-term damage to the vehicle. When driving through water, slow down to minimize waves, and cleaning the undercarriage afterward will save you trouble.
