9 Ways To Identify Flooded Vehicles



In the aftermath of flooding in most part of the country and the world over, vehicles tend to be flooded. The flooded vehicles in most cases are either resold to an unsuspecting buyer, or some people take their time to fix it in some scenarios. A trained eye or mechanic is needed to check if your newly purchased car is a flooded one or not. In this list, we will help you to identify flooded vehicles before you purchase.

1. Check For Foggy Windows

By design, cars are meant to be watertight when used in normal conditions. Even if you do use your car regularly in the rain and place a wet umbrella on the floor on a daily basis, the amount of water needed to make the car windows fog up from the inside while parked is substantially higher. Usually found on older cars due to blockages in inbuilt drainage systems (leaves and dirt residue), most modern cars, especially parked in a closed area should not suffer from these issues. The presence of a foggy window especially after a car is parked for a while means there is considerable water or moisture residue inside the vehicle.

2. The Sniff Test

When left to soak into the likes of seats, carpets and upholstery, water will leave a very distinct musty odour even after it has been dried off. The easiest way to sniff out whether the car has flood damage is to literally sniff it. It is very difficult to completely rid a flood-damaged vehicle of its mouldy smell and mildew. If it does exist, that is a sure shot sign of flood and water damage. If not water damaged, this can be a sign of cars that leak water from the firewall or the doors. Quite a few owners could cover the smell using a strong air freshener. While the smell of air freshener can be pleasing, beware that they may be hiding the odour of a flood-damaged car.

3. Feel Around For Moisture

Smelling a car might be the first step towards detecting moisture but more often than not, it is your sense of touch that will actually find it. It is very important to actually check every nook and cranny of a used car before buying one. Lift the mats out and check for moist carpets especially around the likes of the seat rails. Also, check the firewall insulation for signs of being removed and refitted haphazardly. More often than not, the whole carpet has to be physically removed to dry once a car has gone through a high degree of water and can rarely be fitted back with the same degree of perfection that you see on a factory floor. There will also be several missing plastic clips that hold the carpets in place. It’s always the smaller details that dealers tend to miss while putting a car back together.

4. Check the Boot

Be sure to open the boot and feel around the carpet there. Most modern cars will also have side slots for storage so check those for any sign of water damage or water residue. The boot must be bone dry for it to be an undamaged car. Take out the spare tire and feel the material underneath. Often there might not be any carpeting there, especially in budget offerings and hatchbacks, but check for water collecting here or gins of rust. Also, check the jack and jack handle along with the tool kit for signs of premature rusting. This is a location where water tends to collect, and shady sellers often tend to miss it while fixing a flood-damaged car.

5. Check for Unlikely Corrosion

Water will find its own way through and there are several places it can hide in a flood-damaged car. Check areas that should usually not be affected by water exposure for signs of untimely rust. This includes nuts and bolts under the bonnet, rust in door/bonnet/boot hinges and rust under on places like the screws that hold the sunshades or door handles in place. If the latter two have rusty screws, rest assured the car in question has been completely submerged in floodwaters.

6. Check the Upholstery

A car with brand-new seat covers installed just before the seller tries to sell it is often hiding a secret. Ask for the covers to be taken off and the seats be inspected in their original form. If the seller refuses, walk away from the deal, there is some sort of water damage to the seats. An older car with carpets that looks new with minimal signs of use is another sign of parts that have been replaced for a car to look new. The same goes for miscoloured or mismatched interiors too.

Often, flood-damaged cars have the seats and interior trim shampoo washed that can leave it discoloured if done hastily. Also, check for muddy or water induced stains on the door cars and seats. Push the seat back as flat as it can go to check the seam between the seat backs and the seat bottoms – often this area is telling of the quality of the seats. That said, there is a flip side to this. You will, in your quest to buy a used car, find one that is genuinely well maintained and well cared for. The car will have a spanking clean interior with clean carpets and seats. It is up to you to decide what looks genuinely well-kept and maintained and what looks as if it is covering up for something hidden.

7. Check all Electronics

Electronic bits and water are enemies by nature. The easiest way to detect water damage is to see if all electronics on the car are working accordingly. When you turn on the ignition, check if all the dashboard lights come on (including the speedometer backlight). Check if the air conditioning works without emitting a musty smell.  Also, check that the re-circulating vents/inlet vents option actually change the way the air flows.

Also, check the headlights, taillights and the indicators and check the actual lamps themselves for any sign of water seepage/condensation/damage. Check the roof lights for malfunction, as these are smaller details that dealers might forget to check. Turn on the audio and check for the door speakers sounding funny or crackly. The sign of static interference is also a sure shot sign of water damage. And finally, put your head under the dashboard and check if the wires feel fragile or hardened. If so, that again is a sure shot sign of major water damage.

8. Check the Oil

Often, engines that have had water penetrate them can be easily recognized by checking the oil quality. Check both oil levels and the way the oil looks for tell-tale signs of water damage. If the oil is a pale or chocolate colour instead of being the regular dark shade that it is meant to be, the car has most likely had some sort of water damage (or equally bad – a leaky head gasket!!). Water damaged oil will also be sticky to the touch and might not feel as smooth as it should.


9. Vehicle History

Check the date and place of transfer to see if the car came from a flood-damaged state and if the title is stamped “salvage.” If you are still suspicious, purchase a vehicle history report of the vehicle, which should tell you if a car has ever been tagged as “salvage” or “flood damaged” in any state. This is an important document because it will give you an idea of when and where the vehicle has been before you carry out a physical inspection.
