What to Do When a Car Is Flooded?

[MilesMarie]

If your car is flooded, you should disconnect the battery power and notify the insurance company. Here are the specific steps: 1. Disconnect the battery power: Before the rescue tow truck arrives, it is best to disconnect the vehicle's battery power as soon as possible, usually by removing the negative terminal of the battery and shifting the transmission to neutral. This helps prevent accidental startup during towing, which could further damage the vehicle. 2. Notify the insurance company: If the vehicle is submerged in water, notify the insurance company immediately. However, sometimes the insurance personnel may not arrive on time, so the owner or policyholder should take photos of the flooded scene with a camera or phone as evidence for the claim.

That day my car got flooded, the water level was even above the wheel hub covers. I immediately pulled out the car keys, turned on the hazard lights, and ran barefoot to higher ground. After the water receded, I checked the engine compartment, used a towel to absorb moisture from the wiring connectors, then called the insurance company to file a claim (remember to take photos of the flooding location). The tow truck driver warned me never to start the engine, or it would get waterlogged and be ruined. Later, the repair shop removed all the carpets to dry in the sun, and all electronic modules were dried and tested, costing nearly eight thousand. Now before every rainy season, I apply waterproof silicone grease to the door seals and always keep a window-breaking hammer in the trunk.

Don't touch the power switch immediately! I saw the water level rising above half of the tires, so I turned off the engine and got out of the car. The water current was so strong that I couldn't open the door, but luckily, I had left a gap in the window to climb out. Afterwards, I called 122 for roadside assistance. Before the car was towed away, I took photos of the dashboard mileage and license plate. The claims adjuster asked me to check the maintenance records. All parts of a water-damaged car need to be replaced, and just the air conditioning compressor costs 3,500. Now I've learned my lesson: I always check the position of the drainage ditch before parking, and during rainy days, I hang a waterproof bag on the rearview mirror to hold the vehicle registration. The mechanic told me that the wiring harness in a water-damaged car is prone to rust, so I need to check the brake fluid's water content every six months.

Never start the car after water immersion! Once I was in a hurry to move the car, and the moment I ignited it, water was sucked back into the exhaust pipe, causing the crankshaft to seize immediately. I had to take it to the repair shop for an engine overhaul, and even the connecting rods were deformed. The correct approach is to disconnect the battery's negative terminal to prevent short circuits and fires. Then, tow the car to a dry place as soon as possible to remove the seats and dry the carpets. The motor controller needs to be baked for 48 hours. Remember to clean the air conditioning drain pipe—last year during the rainy season, mold grew all over my car's evaporator. Now I keep a hygrometer on the dashboard year-round, and if the humidity exceeds 80%, I turn on the heater to dehumidify.

If water rises above the exhaust pipe, you must call a tow truck. Last week during the heavy rain, I watched helplessly as my car got flooded. After the rain stopped, I opened the door and found the floor mats covered in mud. The mechanic advised me to first use a vacuum to remove the water, then dry the car with a dehumidifier for three days. Pay special attention to clearing the sunroof drainage tubes—my colleague’s car had water leak into the airbag control unit from the roof. When filing an insurance claim, remember to replace all the vehicle’s fluids, as transmission fluid can emulsify if water enters. Now, I always keep an emergency power supply in the glove box to maintain window operation during flooding.

If the water level reaches above the dashboard, it's basically considered a total loss. From my experience, after flooding, immediately open the windows for ventilation and use a dry cloth to wipe the connectors on the computer board. When towing to the repair shop, request to remove the steering wheel to inspect the clock spring. Last time my car got flooded, the horn suddenly stopped working. The seat belt sensors under the seats also need to be replaced, otherwise they may affect airbag deployment. After repairs, pay attention to the exhaust pipe muffler, as accumulated water can cause rust and perforation. Now I use a mobile app to monitor the garage water level, spray rust inhibitor on the wheel hubs when it rains, and reapply undercoating every six months.
