Is Water in the Car Exhaust Pipe Serious?

[DiPeter]

Water entering the car exhaust pipe is quite serious. The impact on the vehicle includes the following: 1. Clogging the three-way catalyst or damaging the oxygen sensor: Water in the exhaust pipe can lead to severe consequences like water entering the engine. If only the exhaust pipe has water, the accumulated water should be removed as soon as possible to prevent impurities in the water from clogging the three-way catalyst or damaging the oxygen sensor. To drain the water, simply press the accelerator to increase the exhaust flow and expel the water. 2. Engine stalling: Water in the exhaust pipe can cause blockage, leading to poor exhaust flow and resulting in engine stalling. 3. Engine not flooded, just stalled: In this case, there is no need to worry. Once the water drains out, the vehicle can be restarted normally.
