What should I do if the car stalls when crossing the waterway? Is the engine flooded?

But at this time, after the exhaust pipe is flooded, you must never start the car again. If you start the car again at this time, the engine will get water. At this point, the engine will be turned off. Where should I park my car and wait for help?

If the engine is turned off in the water and then started, the problem will be big. Water directly enters the cylinder and then starts. Because water can't be compressed like air, but the piston is still moving, it is easy to break the piston connecting rod or valve at this time. This is a big problem.

So turn off the water and don't start it again. Just waiting for help.

When passing through the water, make sure that the water does not reach the exhaust pipe, and then pass through the throttle with low gear and high throttle.
