What to Do When the Exhaust Pipe Gets Waterlogged?

[VonVivienne]

When a car's exhaust pipe gets waterlogged, you can take it to a 4S shop for a simple cleaning and drying, which will allow the engine to function normally. If the exhaust pipe is waterlogged and the engine stalls, do not attempt to force a restart. Instead, immediately call for roadside assistance.

I remember last year during the rainy season, my car's exhaust pipe took in water after going through a deep puddle, and the engine stalled. I immediately pulled over to a safe spot and turned off the engine, not daring to restart it, knowing that water could backflow into the engine and damage the cylinders. Later, I called a tow truck to take it to the repair shop, where the technician drained the water and checked that the sensors were fine. The lesson is to avoid driving through flooded areas during the rainy season—if the water level is above the exhaust pipe, don't go through it. It's also a good idea to regularly check if the drainage holes under the car are clogged during routine maintenance, rather than regretting it after something happens. This incident didn't cost much but could prevent serious vehicle damage. Remember to drive safely and never force your way through deep water.
