What should I do if the engine is flooded? Is it harmful?

The engine is damaged by water, which is fatal to the interior of the vehicle. Once the engine is flooded, the spark plug can't ignite or even turn off directly. When it is serious, it will cause serious problems such as cylinder pulling, cylinder explosion, connecting rod cracking and crankshaft bending. Therefore, if the engine is flooded, remember not to try to start the car and contact professional rescue in time. The harm of engine water intake is considerable, but we can take effective measures to deal with it. Specifically: 1. If the engine only mixes water vapor into the air filter, we only need to simply handle it and clean the water vapor from the air filter, throttle and other engine-related accessories. 2. If the engine is flooded, but it does not affect the normal operation, but the sound is loud, it may be that there is a small amount of water in the engine oil and gasoline, so it is necessary to change the engine oil and clean the engine related accessories. 3. If the vehicle doesn't start and the engine is seriously flooded, we need to drain the water, clean the interior, reassemble and replace the oil. At the same time, check the observation circuit and clear the possible short circuit. Also check whether the brake system is flooded to ensure that the brake system works normally. Engine water intake is a very serious problem, which must be dealt with in time to prevent irreversible damage.
