Will Water Enter the Interior of an Off-Road Vehicle When Wading?

[LukeFitz]

Water will not enter as long as the engine is running, because the exhaust pressure in the exhaust pipe is greater than the water pressure, preventing water from flowing back in. However, if the engine stalls and the water level rises above the exhaust valve of the engine cylinder head (or the highest point of the entire exhaust system), water can enter the engine. Here are some important considerations for off-road vehicles when wading through water: Maintain a moderate speed: Off-road enthusiasts often say, 'Drive fast on sand and gravel, but slow through water.' Driving too fast can create a high wave in front of the vehicle, increasing resistance and the risk of submerging the engine. Use a low gear: Keep the throttle steady, select a low gear before entering the water, avoid shifting during the wading process, and maintain a consistent engine speed to ensure strong power and adequate exhaust pressure in the exhaust pipe.
