Because after the car is flooded, water will enter the engine from the intake port. At this time, water will be stored in the cylinder chamber. When the spark plug is against water, if the car owner starts the engine, it will bend the piston connecting rod, or even leak the cylinder head, causing irreparable losses.

If the car wades into the water, the engine stalls in the water, which means that the inside of the engine has been damaged by water. If we continue to try to start the car, it may cause the piston cylinder of the engine to break, which will cause fatal damage to the engine. Therefore, once the car extinguishes in the stagnant water, we should find help as soon as possible, push the car to the side of the road without stagnant water, can not stay on the car for rescue, because once the water is deeper and deeper, it is likely to make the entire engine compartment water, which is very serious damage to the automotive electronic components.
