The car cannot restart after stalling in water.
Stalling means that the engine stops rotating. Stalling in water means the car enters water that exceeds the permitted fording depth.
There are approximately two reasons why a car stalls in water:
First, the water has damaged the engine, causing it to stall. The second is a malfunction causing a shutdown.
In the first case, the reboot will usually fail and will only extend the outage. No matter the situation, water will enter the engine through the exhaust pipe once the car is stuck in the water. Even if the restart is successful, water entering the engine will cause serious engine damage. Without starting, post-treatment simply involves removing water without having to replace any parts.
The permitted fording depth of a car is indicated in the manual. But in reality, the impactIt is often not of such magnitude. It is generally believed that when the water depth reaches the bottom edge of the exhaust pipe or the spoke of the wheel (one of the two), the maximum fording depth is reached.
Some off-road vehicles, or temporarily modified vehicles, will increase the circuit position, seal the bottom of the engine, and raise the position of the intake and exhaust pipes to achieve greater wading depth . Keeping in touch is just a way to wade through the water beyond the target taking advantage of the vehicle's characteristics, not the technical capabilities of the vehicle itself.
