Is it possible to reverse in a waterlogged section?
2 Answers
Yes, and the possibility of stalling while reversing through water is significantly reduced. Here are the relevant details: 1. Principle: Due to the presence of gas in the exhaust pipe, under normal pressure (water depth of about half a meter), water will not flow backward. Therefore, the key to deep water fording is controlling the speed to avoid splashing water waves from entering the engine compartment. Additionally, the radiator fan should be temporarily turned off before fording to prevent splashed dirty water from damaging the electrical system. 2. Specific situation: After exiting the waterlogged area, the brake pedal should be lightly pressed continuously to remove residual water from the brake system and restore braking performance. If you are really unsure, you can engage the R gear to reverse through the water, which is highly unlikely to cause the engine to stall. Even if you rev the engine hard and then release the throttle, the engine remains stable with no signs of water flowing backward.
Backing up in flooded areas is extremely risky, and from experience, I really shouldn't attempt it. The engine's exhaust is at the rear of the car, making it easier for water to flow in when reversing. Once water enters, the engine can stall or even suffer catastrophic failure immediately, and repairs can cost thousands or even tens of thousands—no small matter. Additionally, reversing offers poor control, and you can't see changes in water depth behind you. If you get stuck in a deep pit, the front of the car sinking is even more dangerous. I once accidentally reversed into a water-filled pit during a heavy rainstorm, and the engine was totaled—finding a tow truck was a nightmare. When the current is strong, tires slip more easily, and the steering can go haywire, increasing the risk of accidents. Safety first—if the water depth exceeds the center of the wheel hub, don't even try. It's best to drive forward slowly through the water or simply take a detour. Remember, cars aren't boats—don't gamble with your life.
