Can the car be started after water recedes from the exhaust pipe?

Yes, the car can be started after water recedes from the exhaust pipe. When water just submerges the exhaust pipe, it cannot enter the engine cylinders. After the water recedes, the water level in the exhaust pipe will definitely drop again, meaning the farther it is from the exhaust outlet, the less likely it is for the water to be sucked back into the engine when starting the car. Method for starting after water recedes: Ignite and start the car, let it idle without pressing the accelerator. During this time, a lot of water will be expelled from the exhaust pipe until it stops dripping, which takes about 8 minutes. Precautions when starting the vehicle: First, turn the ignition switch to the second position (ON) to light up the dashboard and check if the indicators are normal. Lightly press the accelerator pedal once and release it to ensure the throttle valve opens briefly for smooth air intake. Also, check if the heater, audio system, and headlights are turned off to reduce electrical load during startup. Wait a few seconds to allow the anti-theft authentication to complete and for the fuel pump to build up sufficient oil pressure, which facilitates starting the vehicle, reduces startup time, and avoids damage to the battery and starter. Effects of a flooded car: A water-soaked car is highly prone to rusting of body components, shortening its lifespan and reducing safety performance. Water damage can cause corrosion and rusting of the vehicle's wiring, leading to sudden engine shutdown or spontaneous combustion due to short circuits while driving. The repair costs for water-damaged vehicles are very expensive; in cases of severe flooding, repair expenses may exceed 50% of the car's original value.
