How to Determine if a Car Has Been Flooded
2 Answers
Disconnect the negative terminal of the battery as soon as possible to prevent electrical short circuits in various vehicle components due to water exposure. First, check whether the engine cylinders have been flooded, as water ingress can bend connecting rods and damage the engine. Water contamination in engine oil will cause it to deteriorate, losing its lubricating properties and leading to excessive engine wear.
As an experienced driver who has been behind the wheel for many years, I remind everyone to thoroughly inspect their vehicle after a storm. I usually start with several key areas: first, crouch down to check for wet stains or water marks under the car's carpets and seats, especially in the often-overlooked rear seats; then, get close and sniff for any musty or damp odors, which are often the most direct signs of water intrusion. Next, pop the hood and inspect the battery and wiring connections for rust or water droplets, as accumulated water can cause short circuits or engine ignition issues. Don't forget to recall whether you've recently driven through water or parked in a flooded area—if the wipers or headlights mysteriously fail, water damage is likely the culprit. Finally, schedule regular rust-proof maintenance at a professional shop, as untreated water intrusion can accelerate chassis corrosion and compromise safety. In short, seeing is believing—never take it lightly.
