Will Water Definitely Enter the Engine If Restarted After Stalling in Water?

[EllianaLee]

Restarting the engine after stalling in water will definitely cause water ingress. Here are the relevant explanations: 1. Reason: Water can enter the intake system through the air intake, forming an air-water mixture that enters the engine cylinders. While air can be compressed, water cannot. When the crankshaft pushes the connecting rod to compress towards the piston, the incompressible water will cause the connecting rod to bend. Without proper repair, the bent connecting rod rubbing against the cylinder wall poses a risk of breaking both the engine block and connecting rod. 2. Precautions: If your vehicle stalls in water, never attempt to restart the engine. Normally, without restarting, simply draining the engine and inspecting/replacing components like the air filter at a repair facility suffices. However, restarting after stalling risks engine damage, necessitating thorough inspection at a repair shop to assess potential damage.
