2 Answers
Here are the methods to handle water in the exhaust pipe: 1. Go to a 4S shop for drying: After water enters the car's exhaust pipe, you can go to a 4S shop for simple cleaning and drying, which allows the engine to function normally. The repair cost is relatively low, usually just a few hundred yuan. If the water ingress is not severe, such as after driving through shallow water, you can also check the electronic systems and whether there is accumulated water under the car body yourself. If the engine must be started, remove the spark plugs first to drain some water from the engine, then reinstall them before starting. 2.

I was driving through a deep water area on a heavy rainy day when the car stalled as water entered the exhaust pipe, which really startled me. I immediately turned off the engine to prevent it from starting, called for a tow truck, and sent the car to the repair shop. The mechanic checked and found that no water had entered the engine internals, so they just drained the accumulated water and cleaned the exhaust pipe for me, costing a little over 100 yuan to fix. This experience taught me that when driving through water, it's crucial to assess the depth of the road, slow down in advance to avoid splashing, and never attempt to start the car if water gets in—instead, have it towed for professional handling immediately. The money saved from avoiding major repairs could easily cover a nice meal. Now, I always check the weather before heading out, because safety comes first above all else.
