Can a Flooded Car Be Started?

[Kirk]

Do not attempt to start a flooded car. Vehicles are equipped with various electronic components and sensors. If water enters the interior, starting the engine can cause damage. If your car is flooded, you should immediately contact your insurance company and the 4S shop. When the water level exceeds the car's chassis, it is referred to as a water-damaged vehicle. Flooded cars can be categorized into three scenarios: water level reaches the exhaust pipe but not half the wheel height, water level just reaches half the wheel height, and water level exceeds half the wheel height. Generally, water reaching half the wheel height can already affect the vehicle. Below is a detailed explanation: Water level reaches the exhaust pipe: If the water only covers the exhaust pipe, you can drive the car away promptly. Water in the exhaust pipe will not be sucked back into the engine. Engine stalling is mainly caused by water entering the engine's intake system and is unrelated to the exhaust pipe being submerged. Water level just reaches half the wheel height: If the water reaches half the wheel height, the car usually won't leak. However, if submerged for an extended period and if the sealing strips have aged, leakage may occur. In such cases, drive the car to a 4S shop, remove the interior components, and clean and dry them. Water level exceeds half the wheel height: If the water exceeds half the wheel height, the engine may take in water, and the interior may also leak. Under no circumstances should you start the engine, as this could lead to engine or electronic component damage. Starting a flooded car causing damage will not be covered by insurance.
