Can the Engine of a Flooded Car Still Be Used?
2 Answers
It is best not to use the engine of a flooded car. For vehicles that have been flooded but repaired without completely eliminating hidden dangers, the risk of continued use is relatively high. Severe cases may result in vehicle self-ignition, damage to the engine, transmission, airbags, and other components. Here is some related information about water entering a car: 1. Hazards: If water enters the car, many electronic devices inside can be affected by water, leading to short circuits and damage. If water enters the engine through the intake, it can cause engine damage. The consequences of water entering the engine are very serious, ranging from major engine repairs to potential engine scrapping. 2. Precautions: During heavy rain, car owners should avoid driving and preferably park their cars in higher areas to prevent water immersion. If water rises above the doors and enters the car after driving through water, it indicates the car has been flooded. If the car is found to be flooded, check if it can still start. If the car can run without any apparent issues, the first step is to deal with the accumulated water inside.
Whether a water-damaged car engine can still be used depends on the specific situation. Last time my car was flooded, the water reached the tire height, and I immediately towed it to a repair shop for inspection. The mechanic said if water entered the engine intake or cylinders, starting it would be disastrous, potentially causing hydro lock and damaging internal components. If the submersion time was short, thorough cleaning might make it usable, but sand and debris in the water can corrode metal, leading to long-term issues. After my car was flooded, I had the fuel and electrical systems cleaned for 800 yuan, and it's been running fine for two years, though I have to check for rust regularly. My advice: never attempt to start a flooded engine—call a tow truck and have it professionally assessed to avoid regrets.
