What Happens When Starting the Engine with a Flooded Exhaust

[HZoe]

Starting the engine with a flooded exhaust depends on the amount of water intake. A small amount may not cause significant issues, while a large amount could lead to secondary stalling and engine damage. Scenario with minimal water intake: If a small amount of water enters the car's exhaust pipe, it will gradually be expelled with the exhaust gases during continued vehicle use, without causing noticeable effects on the vehicle or engine. Scenario with substantial water intake: Excessive water intake can affect the engine, causing it to stall while driving. If the car stalls due to significant water intake, do not attempt to restart the engine immediately. Since the engine's air intake has already taken in water, a secondary ignition attempt can cause severe damage to the engine.
