What to Do If the Engine Gets Waterlogged in Rainy Weather?

Do not attempt to forcibly start the engine after it has been waterlogged, as starting the engine under such conditions can cause severe damage and may void any insurance claims. If the vehicle has been submerged in water and cannot be started, push it out of the deep water area. You can remove the spark plugs to manually cut off the fuel supply system and ignition system. Check for any signs of turbidity or foaming in the engine oil. If present, replace the oil immediately or contact a repair shop as soon as possible for corresponding maintenance and inspection.
I remember encountering engine water ingress during rainy weather last year, which was quite frightening! Engine water ingress usually occurs when driving through deep puddles, where water is sucked in through the air intake, causing the engine to stall or even suffer severe damage. The first step is definitely to stop the car and turn off the engine immediately—never attempt to restart it, as forcing it could worsen the problem. Then, I quickly checked the air filter; if it was wet, professional handling was needed. That time, I called a tow truck to take it to the repair shop. The mechanic disassembled it and said it was lucky I didn’t restart the engine, or else the piston rods could have bent, leading to repair costs of several thousand. Since then, I always check water depth during rainy days and avoid any puddles deeper than half the wheel height. Prevention is better than cure, and regular inspection of the vehicle’s intake system is also crucial to ensure a safe journey.
