Latest update date: February 02, 12

Water hammer, also known as engine flooding, is a phenomenon where water enters the combustion chamber of a car engine through the air intake. When this happens, the engine will suddenly stall. If you try to restart it, water will be sucked deep inside the engine, causing serious damage and expensive repairs.

According to the 2023 flood damage assessment report, 78% of vehicles flooded above the dashboard level were determined to be total losses, with repair costs exceeding 60% of the vehicle's pre-flood value.

Flooded cars not only cause damage to the interior but also seriously affect the engine and electrical system. According to experts, when water reaches the hood, the car is at risk of being completely damaged due to hydrostatic shock. Here are 10 things to do immediately when your car encounters this situation.

Flooded/Hydro-hammered Cars – Things to Know

Do not attempt to start the vehicle.

First and foremost, do not attempt to start the car. If you do, water could enter the engine, leading to hydrolocking – a dangerous condition that can cause serious engine damage. Push the car out of the flooded area and call for help.

Contact your insurance company immediately

Contact your insurance company as soon as you have an accident. They will help you assess the extent of the damage and guide you through the steps required to make a claim. Depending on your policy, you may be entitled to some or all of the repair costs.

Determine flood level

Check the water level in your car by looking at the markings on the body of the car. If the water has reached the dashboard, the damage is very high and you should take the next steps to deal with it quickly.

Drying furniture

After removing the vehicle from the flooded area, open all the doors to let the water drain out. Use dry towels to absorb water from the floor, then use a fan or large hair dryer to dry the interior. This is important to avoid mold and damage to interior parts such as leather seats and carpets.

Check the head and air duct system

If you have mechanical experience, check the oil system and air filter. Change the oil if necessary, but make sure no water has entered the engine before doing so.

Test all types of solutions

In addition to engine oil, check other fluids such as brake fluid, power steering fluid, and coolant. This helps ensure that there are no leaks due to water ingress.

Check the electrical system

If the car still starts, check all electrical components such as lights, air conditioning, and sensors. Any signs of failure could be the result of water entering the electrical system.

Check around wheels and tires

Before driving, check your wheels and tires for any dirt or debris. This will help ensure that braking performance is not impaired.

Prepare yourself for the worst

If the technician cannot diagnose or repair the vehicle, be prepared for the possibility that the vehicle could be totaled. This will give you a more proactive approach to resolving the issue with your insurance company.

Remember the car's flood history

Finally, keep a record of your car's flood history to help technicians identify problems in the future. This will also be helpful if you decide to sell your car later.

Consequences when cars are flooded

Flooded cars can experience several serious problems:

  • Engine damage: When water enters the engine compartment through the air intake, it can cause hydrolock, damaging the connecting rod or cylinder.
  • Electrical Short Circuit: Water can cause short circuits in the electrical system, affecting the ability of electronic devices to start and operate.
  • Decreased Vehicle Value: A car that has been flooded will often lose a significant amount of value on the market.

Timely and proper handling of a flooded car will help limit damage and save significant repair costs in the future.

The average repair cost for a flooded vehicle ranges from $20,000 to $40,000, with engine replacement accounting for 45 percent of the total cost. Data from 5,000 cases shows that prompt professional intervention can reduce repair costs by up to 60 percent.
