At what water depth will the engine take in water?

[PeterAnn]

Water depth of 20 cm can cause the engine to take in water. Here are the relevant details: Ways for water to enter the engine: First, due to the low position of the engine intake pipe inlet, water can be sucked into the engine when the vehicle is wading. Second, if the exhaust outlet is below the water level, water can be drawn into the engine through the exhaust outlet when the vehicle is wading. Consequences of water entering the engine: The engine will inevitably stall after taking in water. Since water entering the cylinders lacks lubricating properties, blindly restarting the engine after stalling may cause severe damage (such as cylinder scoring), leading to engine failure. In such cases, insurance companies typically will not cover the damages.
