How long after a car is flooded can it be started?

After a car is flooded, first check whether the air filter on the engine is wet. If it is not wet, the car can be started at any time. The following is a relevant introduction about starting a car after it is flooded: Water level height: If the water level does not exceed the engine, because the engine's cylinder from the oil pan and the cylinder block have tight sealing performance, water entering the engine and causing damage can only occur if the water level is higher than the engine for a long time. Hazards of a flooded car: The air resonator box is located between the air intake and the intake hose. Its function is to reduce intake noise, stabilize airflow, and prevent a small amount of rainwater from entering the combustion chamber. It is generally located between the front wheel and the front bumper, where water can easily reach. Once the resonator has water, a large amount of water will be sucked into the combustion chamber when the engine is started, and the incompressibility of water will cause devastating damage to the engine connecting rod. This is also the fundamental reason why it is emphasized not to start the engine when the car is flooded. The starter is usually installed at the bottom end of the engine block and can easily be submerged in water. Because the starter does not have the high airtightness of the engine, water will quickly penetrate inside. Once the engine is started, it may cause an internal short circuit in the starter, resulting in burnout.
