What to Do If Water Enters the Exhaust Pipe?
2 Answers
If you encounter water entering the exhaust pipe and the engine stalls, do not attempt to force a restart. Instead, call for rescue services immediately. After simple cleaning and drying, the engine will resume normal operation. The repair costs are relatively low, and insurance companies are likely to cover the claim. When driving through water, try to follow the principle of 'fast on sand, slow in water' to avoid rushing through. This is because the waves created by the wheels can easily enter the exhaust pipe, causing the vehicle to stall.
I've seen quite a few cases of water entering the exhaust pipe at repair shops, usually caused by driving through water. If you notice your car suddenly stalls, white smoke coming from the exhaust pipe, or hear water sounds, don't panic. The most crucial thing is not to attempt a second ignition, otherwise the engine might be completely ruined. First, push the car to a safe spot and cut off the power, then check the air filter box for any water stains. If the water intake isn't severe, simply remove the exhaust pipe to drain the water. However, if water has entered the engine, you'll need to remove the spark plugs to drain the water and use compressed air to dry out the cylinders. Last time I rescued a water-damaged car, it took two days at the repair shop to get it properly cleaned, so when driving in the rain, you really need to assess the water depth before proceeding.
