2 Answers
The methods to deal with water entering the vehicle after driving through water are: 1. Park in a safe location and check if the engine ignition system is wet, then use a dry cloth to wipe the damp electrical components; 2. Call for roadside assistance; 3. Disconnect the negative terminal of the battery; 4. Check the brake fluid and the brakes on all four wheels; 5. Inspect each gearbox for water ingress and ensure there are no obstructions between the radiator fins; 6. Check the tires for any damage. The reasons for water entering the vehicle after driving through water are: 1. Poor sealing of the door inner panels; 2. Blocked drainage holes at the bottom of the doors; 3. Water entering the air intake duct between the front hood and the windshield wipers.
After driving through water and finding the car flooded, I think the first thing to do is to stop the car and turn off the engine immediately—safety first, don’t push through. Then, absolutely avoid restarting the engine, as water entering it could damage components, leading to exorbitant repair costs. I usually park on higher ground and check the engine bay for water intrusion, especially around the air filter. If water has splashed inside the cabin, quickly soak up the water from the carpets with towels or use a fan to dry them, otherwise mold could become a serious issue over time. After that, call a professional repair shop right away for an inspection, focusing on the electrical system and engine—some hidden issues aren’t visible to the naked eye. I remember once neglecting this, and it resulted in a short circuit that required replacing the entire system, which was a huge hassle. In short, handling it safely is the priority—don’t overlook these small details just to save trouble.
