What should be done after a car is flooded?

First of all, do not start a flooded car, otherwise the intake system will draw water into the engine. The car should be towed to an auto repair shop for treatment. After being flooded, the car's computer board and wiring harness must be thoroughly cleaned. If the computer board is damaged, the car body chassis must also be treated to prevent rust. The floor mats must be removed, all water inside the car body must be drained, and rust prevention measures should be reapplied. It is also best to replace the wiring harness and computer board to avoid safety hazards.

Last time my neighbor's car got flooded, he panicked in a fluster. Remember, never attempt a second start! Starting the engine after water immersion will directly cause it to be scrapped. First, call someone to push the car to higher ground and immediately disconnect the negative terminal of the battery—this trick can save the onboard computer. Quickly contact your insurance company to report the incident, and take photos of the waterline and VIN within 24 hours. Finally, call a tow truck to haul the car to a repair shop to remove the seats and dry out the floor mats. Don’t power it up before it’s completely dry—I’ve seen flooded cars grow green mold from not drying properly.

A water-damaged car is like a water-damaged phone—you need to act fast and decisively. I recommend three steps: First, prioritize safety—don't risk opening the door if the water level is above the wheel hubs. Second, minimize damage—disconnect the battery before calling a tow truck, and take photos to document the flooding level. Third, focus on repairs—demand that the repair shop remove all carpeting and thoroughly inspect the transmission and brake fluid. Remember to replace any water-contaminated brake fluid, as water mixing into the brake lines can be deadly.

Stalling in shallow water and complete submersion are worlds apart! When water just covers the tires, immediately open the door, exit the vehicle, and disconnect the battery. Letting it dry for three days can usually save it. But if water has submerged the dashboard, don't hesitate—report it as a total loss. At that depth, even if repaired, it'll be a constant headache—circuit boards corroding like rust in saltwater, AC ducts trapping stagnant water, and a moldy stench strong enough to knock you out after six months of driving. Never buy a car with a waterlogged center console just to save money!

Veteran drivers have seen too many flood-damaged cars turn into scrap metal. Here's a tough trick: after the water recedes, first check the dipstick - milky white oil indicates water in the engine. Don't believe those online 'baking' methods, take it to a professional shop to drain all vehicle fluids. The most deceptive part is the wiring harness connectors - they may look dry but the pins oxidize, leading to sudden window failures (and that's the mild scenario) within six months. If you're serious about repairs, have the mechanic disassemble and clean every connector, otherwise expect constant trips to the repair shop.
