What to Do If Your Car Stalls in Water?

When driving through flooded areas, there’s always a risk of your car stalling in water. This can be a stressful and dangerous situation, but knowing the right steps to take can help you stay safe and minimize potential damage. 

In this article, we will guide you through the necessary actions to follow if your car stalls in water.

Assess the Situation

Before taking any action, it’s crucial to assess the situation and gather information that will help determine the best course of action.

Determining the Water Depth

Check the depth of the water surrounding your vehicle. If the water is below the bottom of your car’s doors, it may be safe to proceed. However, if the water level is higher, do not attempt to drive through it.

Evaluating the Surroundings

Take note of the surroundings for any potential hazards, such as downed power lines or fast-moving currents. Assess the stability of the water and look for an exit strategy.

Turn Off the Engine

Once you’ve determined that it’s safe to do so, turn off the engine immediately after stalling in water. This helps prevent further damage to the internal components of the vehicle.

Prioritizing Safety

Your safety is paramount, so ensure that you turn off the engine only when it’s safe to do so. If you’re unsure or uncomfortable, focus on exiting the vehicle first.

Avoiding Further Damage

Leaving the engine running can lead to water being sucked into the intake system, potentially causing severe damage to the engine. By turning off the engine, you reduce the risk of hydrostatic lock.

Exit the Vehicle

Once the engine is off, it’s essential to exit the vehicle safely and promptly.

Ensuring Personal Safety

Unbuckle your seatbelt and assist any passengers in exiting the vehicle. Open the doors or windows, or use an emergency exit if necessary.

Moving to Higher Ground

Make your way to higher ground away from the stalled vehicle. Ensure you have a safe distance from the water in case of any unexpected movement or rising levels.

Call for Assistance

After exiting the vehicle and ensuring your safety, it’s time to seek assistance.

Contacting Emergency Services

If you’re in immediate danger or require immediate assistance, call emergency services right away. They can provide guidance and dispatch the necessary resources to help you.

Seeking Professional Help

Even if you’re not in immediate danger, it’s recommended to contact a towing service or your insurance provider to arrange for professional assistance. They can help tow your vehicle and provide further guidance.

Do Not Attempt to Restart

It’s crucial not to attempt to restart the vehicle after stalling in water.

Preventing Engine Damage

Attempting to start the engine can cause water to enter the combustion chambers, leading to hydrostatic lock. This can result in severe engine damage and potentially require costly repairs.

Waiting for Professional Inspection

Wait until a qualified mechanic inspects the vehicle before attempting to restart it. They can assess the damage and determine the necessary repairs.

Tow the Vehicle

Once professional assistance has been arranged, the next step is to tow the vehicle to a safe location.

Choosing the Right Towing Method

Consult with the towing service to select the appropriate method for towing your specific vehicle. Depending on the situation and the extent of the damage, flatbed towing or dolly towing may be recommended.

Avoiding Additional Complications

Ensure that the towing service secures your vehicle properly to prevent any additional damage during transport. It’s crucial to communicate any concerns or special instructions to the towing professionals.

Assess the Damage

After the vehicle has been towed to a safe location, it’s time to assess the damage caused by stalling in water.

Inspecting the Engine and Electrical Components

A qualified mechanic should thoroughly inspect the engine and its electrical components for any signs of water damage. This includes checking the air intake, spark plugs, and ignition system.

Checking for Water Contamination

Inspect the fluids, such as oil, transmission fluid, and coolant, for any signs of water contamination. Water-contaminated fluids may require draining and replacing to prevent further damage.

Dry Out the Vehicle

Once the inspection is complete, it’s important to dry out the vehicle’s interior to prevent mold and electrical issues.

Removing Excess Water

Use absorbent materials, such as towels or a wet-dry vacuum, to remove excess water from the vehicle’s interior. Pay special attention to the carpeting, upholstery, and electrical connections.

Ventilating the Interior

Leave the doors, windows, and trunk open to facilitate airflow and aid in the drying process. You may also use fans or dehumidifiers to accelerate the drying process.

Inspect Fluids and Filters

After drying out the vehicle, it’s necessary to check and replace any fluids or filters that may have been affected by the water.

Checking Oil, Transmission Fluid, and Coolant

Check the oil, transmission fluid, and coolant for signs of water contamination. If any of these fluids appear milky or discolored, they should be drained and replaced.

Replacing Contaminated Filters

Inspect and replace the engine air filter, fuel filter, and cabin air filter if they have been exposed to water. Water damage can compromise their effectiveness and lead to further issues.

Seek Professional Mechanical Assistance

To ensure your vehicle is fully operational and safe to drive, seek professional mechanical assistance.

Finding a Reputable Mechanic

Look for a trusted and qualified mechanic with experience in handling water-damaged vehicles. They can perform a comprehensive inspection, diagnose any hidden issues, and carry out the necessary repairs.

Diagnosing and Repairing Potential Issues

The mechanic will thoroughly examine the electrical system, engine components, and other critical parts to identify any problems caused by the water. They will then repair or replace the damaged parts as needed.

Consider Insurance Coverage

If your vehicle is covered by comprehensive insurance, it’s essential to consider filing a claim for the damages incurred.
