10 Ways to Protect your Car from Water or Flood Damage

During the 2018 Kerala floods, around 17,500 new cars sitting in various dealerships in the state were reported to have gotten destroyed due to the floods. That’s more than a thousand crore rupees worth of cars down the drain. While these were the cars which were not yet sold by the dealership, there were plenty of other cars, already under ownership which the floods wrecked. Reportedly, some luxury cars like Porsche Cayenne, Mercedes GLS, and Mercedes E-class also faced the wrath of this catastrophe.

We all know how cars have been ruthless to our mother nature, so every now and then mother nature tends to get her retribution from our beloved cars. Flood or water damage to cars is as real as it gets. People residing in areas where floods were never an issue may find it hard to realise just how terrifying floods can be for car owners. It won’t be an exaggeration to say that heavy rains keep people living in areas prone to floods up at night as they are worried about their cars.

But this threat to cars is not just prevalent in the coastal areas anymore. This year’s monsoon saw dense waterlogging on roads in some of the prominent regions in North India. The waterlogging was so dense that reportedly cars and even buses got submerged in them.

Knowing how to protect your car in events of flood or waterlogging is now a must for everyone unless you have a knoll reserved for car parking. Hence, today we would like to discuss certain ways in which you can keep your car protected from floods and water damage.

How to prevent your car from water or flood damage

There are two aspects to it, either is that you are on the road while there’s a rainstorm going on or your car is parked outside and is rapidly being surrounded by water.

Prevention from water damage while on the road

  1. Avoid passing through standing water

    Most of have probably made this mistake at some point or the other. One can never know how deep the standing water can be and still go-ahead anyway, that’s where it goes wrong. Your car can stall mid-way and you probably won’t have a way out then. Also, water can seep into the cabin if your car stranded in the water for too long, leading to a lot of damage.

    Hence one should always avoid making theirs through standing water and instead find an alternative route

  2. Keep your car in 1st gear and keep the revs high

    In case you are not able to figure an alternate route and don’t have any other option but pass through the mini pond being made on the road then always keep your car in 1st gear. The benefit of keeping it in first gear and the revs up high is two-fold. One, it lets you keep your car steady at low speeds and have a strong grip on the car’s trajectory. Second, it allows you to drive at higher revs which helps in preventing water coming in from the exhaust.

  3. Drive through the higher part of the road

    If possible, try and get out of the car and assess the road conditions before going you decide to jump into the standing water. Look for the highest part of the road and take your car ahead from there. This simply reduces the chances of your car getting caught up in the middle of the water.

  4. If your car stops in the middle of the water

    This one is not exactly “how to protect your car” and is rather how to protect yourself. If your car gets stuck in the flood and the water is gradually creeping up then it is best to abandon the car and climb out of it. The car is not worth more than your life.

  5. Starting your car back

    If your car stalls in the middle of the water then either turn it back on as fast as you can or don’t do it at all. You should be doing it quickly because you need to crank up the engine before the water tries to seep in. If you get too late and the water level is above the exhaust pipe, in that case starting the car may lead to the worst thing possible, ‘Hydrolock’.

    Hydrolock is when water enters into the cylinder block, damaging the spark plugs, valves, etc and probably making the car incapable to combust fuel.

Preventing your car from flood damage while it is parked

  1. Park your car on higher grounds

    Prevention is better than cure and this point is the best example of that. If you have access to an elevated parking spot, then don’t think twice before pulling up there. This is especially necessary if you own a sedan or a hatchback as they are comparatively lower.

    Position your car on higher grounds during a rainstorm or flood reduces the chance of water making its way into the vehicle and damaging the electronics and mechanical parts.

  2. Pull up the windows

    Make sure that your car’s all four windows are closed properly. There shouldn’t be even a slightest of a gap as this could allow water into the cabin and that can turn out to the scariest thing that can happen to your car.

  3. Disconnect the batteries
