Common Causes Of Water Damage In Cars

There are several possible causes of water damage in cars. The most common cause is flooding which can result after heavy rains or storms. Some roads often struggle to cope with heavy downpours which causes waterlogged portions in the road. Flooding can extremely damage cars, as some might have to inevitably drive through a deep puddle and the extent of damage can be both seen and unseen.

Driving through floodwater is never a good idea because it is impossible to judge the waters depth. Even the smallest amount of water getting inside your engine can cause you to stall. Just a cupful of water which gets in your car’s combustion chamber can be enough to destroy your engine. A foot of water is enough to make your vehicle lose control.

For convertible cars, leaving its top down during heavy rain can also cause water damage. Most car users dont really realize how such a mistake can harm their cars. This is also true to cars with sunroof. Even having windows down during a significant downpour can be risky.

A vehicle can be water damaged when someone accidentally or intentionally drives it into a body of water. The extent of the damage depends on the following factors:

  • How deep into the water the vehicle went,
  • The length of time it was submerged in water, and
  • The type of water .

Before washing your vehicle, be sure to:

  • Fold the side mirrors
  • Close all windows, doors, and sunroofs properly
  • Retract the aerial
  • Disable all the automatic functions of the car, like the windshield wipers.

Many people like to wash their electric cars manually to prevent damage and keep up with maintenance.

If you intend to wash your vehicle with a high-pressure cleaner, be careful not to turn the pressure too high.

Avoid standing too close to the vehicle and set your pressure between 1200 and 1900 PSI.

Keep the nozzle at least six inches away from the car paint and 12 inches away from the trim. Spray water at a downward angle to avoid damaging the cars surface.

Tip : Use A Silica Gel Dry Soak

Remove your damp head unit and do not turn it on. Exposure to water will damage electronic equipment over time. Running current through wet electronics can do immediate and possibly irreparable damage.

Here are the steps:

  • Gently shake the unit to get out as much water as you can.
  • Use a microfiber cloth to wipe any screens or lenses, then pat the units exterior until it is dry.
  • Use compressed air to blow out any stray moisture, but make sure you hold the can straight up, so you dont get more liquid into the unit.
  • Use a hand vac to draw out moisture. Dont get it too close as you dont want static electricity or excess suction damaging the circuits.
  • When you complete these steps, put your head unit in a container and cover it with silica gel packets. Aquapapa Silica Gel Desiccant Packets should be enough to surround most damp head units, and this is the cheapest way to get rid of unwanted moisture from your electronics.

    Cover the container to keep out moist outside air, then turn the head unit over every hour or two to ensure all water seeps out. Let it rest in the silica gel packets for at least 24 hours.

    The silica gel packets absorb moisture from the air. This lowers the containers humidity by as much as 40%. As water evaporates into the dry air from your head unit, the silica gel sucks it up and traps it in tiny, interconnecting pores.

So, if you have a car plagued by flooding or if you know of anyone who is going through it right now, here is a vehicle flood damage checklist you should also have prepared.

    • Survey the damage by understanding how deep the floodwaters are.
    • DO NOT start a flooded car.
    • Either get a towing service to get the car to drier and higher ground or quickly start working on drying out the car to avoid corrosion.
    • Get your insurance company to check out the damages and file a claim for your car.

    With the monsoon already here, we can expect a lot of rain in the next few months. Driving in these conditions can be quite difficult and you have to be aware of your surroundings when driving. Puddles are very common on Indian roads and are a hazard for all vehicles. It is best to avoid them if possible, but if you cannot, you need to go through them slowly and safely. When you encounter a flooded road or a massive puddle, use these above-mentioned tips and steps to ensure that your vehicle is not totaled.

    Can Rain Mess Up Your Car Battery

    If you drive a car, you know that bad weather can sometimes lead to car trouble. One problem you might encounter is a dead battery. When water gets into the battery cells, it can cause a chemical reaction that prevents the battery from holding a charge. This can happen if your battery is old and corroded, or if you accidentally leave your car lights on in the rain. If you think your battery might be damaged, take it to a mechanic or auto parts store to have it checked out.

    It is important to note that car batteries have very low voltage, so even if it is raining, you will not experience an electrical shock. You should proceed with caution in order to ensure the batterys safe recharging. If the weather is good, it is always a good idea to turn off your engine while you are recharging the battery. A large number of drivers are foregoing jumper cables and instead rely on a portable battery charger. Even though portable chargers appear to completely replace traditional jumper cables, it is still a good idea to have them in your vehicle. If your vehicles battery runs low, its a good idea to know when its running out. This is a classic indicator that your battery is running low if it takes longer to start your engine or it sounds sluggish, this is also an indication of a low battery.

    Electrical Problems In Wet Weather

    I drive a 2001 GMC Sonoma SLS. It has 138,000 miles. For the last year, I have discovered an interesting problem. It only happens when I am driving the truck in wet conditions . If Im driving down the road on a rainy evening, every so often, my electrical system starts to struggle. My instrument cluster and headlights will dim significantly, and my defogger fans speed reduces significantly. This drop in power can last anywhere from 10 – 15 seconds. Then, everything comes back to full power. During these lapses, the engine will continue to run normally. The electrical gauge in my instrument cluster shows a drop in charge when this happens. Ive managed to avoid danger thus far, but since I live on an island with a thriving population of deer and rabbits, having good visibility at night is a must. Please help!
