Is It Harmful If a Car Doesn't Stall When Driving Through Water?

Driving through water without stalling does not cause damage to the vehicle. Below are methods for inspecting a vehicle after water exposure: Engine Inspection: Check whether water has entered the engine cylinders, as this can bend the connecting rods and damage the engine. If it is confirmed that water has entered the engine, first remove the spark plugs to manually cut off the fuel supply and ignition systems. Then, use the starter motor to crank the engine, allowing the water inside to be expelled. Check Various System Fluids: Inspect the condition of fluids in all vehicle systems to prevent foaming or cloudiness caused by water ingress, which can degrade the oil and reduce its lubricating properties.
I remember once driving through a deep puddle, and I was quite happy that the car didn't stall, thinking everything was fine. But after a week, I noticed a strange smell inside the car and found damp marks under the floor mats. Later, minor electrical issues started to appear. The car didn't stall because the water didn't reach the air intake pipe, so the engine kept running, but water could seep into the cabin and electrical systems, leading to rust, short circuits, and even mold that affects health. After driving through water, it's best to immediately check the floor, chassis, and fuse box, and dry any accumulated water promptly. Don't underestimate this—my neighbor's car ended up costing a lot to repair the electronic modules because they ignored it. When driving, try to avoid deep water; if it reaches above the center of the wheel hub, it's unsafe.
Last time I drove through a flooded area, the water almost reached the car doors. I was relieved the engine didn't stall, but afterward, I noticed a slight vibration in the steering wheel. Not stalling doesn't mean it's safe—water might have entered the brake system or exhaust pipes, leading to corrosion later. Moisture can especially damage electronic components, like my car's navigation system, which became less responsive. When driving through water, maintain a slow and steady speed to reduce water surges. Afterward, it's advisable to rinse the undercarriage at a car wash and check if the air filter is damp to prevent mud clogging. Don't delay repairs, or the costs could escalate.
