What are the consequences of restarting a car after it stalls due to water ingress?

[DiIker]

If a car is restarted after stalling due to water ingress, water can enter through the air filter, pass through the intake valve, and then enter the cylinder block via the intake pipe. This can potentially cause deformation of critical engine components such as the crankshaft and connecting rods, leading to engine vibration. In severe cases, parts may even break. Below are some additional tips: To avoid vehicle damage when driving through water (e.g., flooded roads), please note the following precautions: 1. Determine the water depth before driving through it. The water level should not exceed one-quarter of the wheel height. 2. Drive at walking speed (15–20 km/h). Higher speeds may create waves in front of the vehicle, which could allow water to enter the engine intake system or other components. 3. Never stop, reverse, or turn off the engine while in the water under any circumstances.
