Will a car definitely be damaged if it stalls in water and is restarted a second time?

[OAllie]

Restarting a car after it stalls in water does not necessarily cause damage. If the engine has not taken in water, there will be no damage, but if water has entered the engine, damage will occur. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning it in a sealed cylinder, causing the gas to expand and push the piston to perform work. The effects of a car driving through water include: 1. The engine may produce insufficient power and experience shaking issues; 2. The high-voltage ignition system may become damp or short-circuit due to water ingress; 3. Water may enter the exhaust pipe; 4. Residual water can prevent the brake discs and brake pads from fully engaging, causing a loss of braking power; 5. Debris can easily adhere to gaps in the chassis, leading to rust; 6. Moisture may form inside the headlights, affecting light transmission; 7. The wiring harness and electrical connectors in the engine compartment may become wet and cause short circuits.
