What To Do If Your Car Stalls In Water?

Some areas are prone to floods on a regular basis as a result of heavy rains or cyclones. What To Do If Your Car Stalls In Water?

If you’re not sure what to do, here’s a step-by-step approach to preventing more damage.

It’s a popular fallacy that cars are water-resistant, and while they can drive in light rain, floods are a different story!

Water and metal (the material that all automobiles are constructed of) do not mix well, as you might expect.

Rust and foul-smelling odors, as well as broken electrical and, in certain cases, a damaged engine, are the usual outcomes.

The following instructions are for circumstances in which you may have parked your car in a flooded basement, left your car windows open by accident, driven into a large water puddle, or the seal on your doors and windows is not watertight enough.

What To Do If Your Car Stalls In Water?

If your car stalls in deep water, you may have to restart it to get back to safety. Please remember that restarting the engine may cause irreversible damage. If you cannot restart your car and find yourself stranded in rising water, abandon it immediately and seek higher ground.

Car Stalls In Water

It’s perilous to drive through water, especially if it’s rushing across the road. It’s very easy for your car to be swept away.

You will also be unaware of the state of the road underneath you. If the water level is more than half the height of a tire, don’t drive through it.

Don’t be the first to jump in if you’re not sure about the depth! Keep an eye out for other vehicles. Drive carefully and steadily if you must drive through water.

Your vehicle may be damaged if you drive through a flooded road. Taking a detour or parking in a safe location until the water recedes is the best option.

If your engine stalls while driving through water, you have no choice except to restart it. This can result in serious engine damage.

Water may wreak havoc on your car’s low-lying components even if it’s not raining. Here are some things to look for if you’re driving in a flooded area.

Check Unusual Sounds

Take your car to the garage if you notice strange noises.

You can avoid serious damage and costly fees by conducting an investigation and repairs in a timely manner. Both you and your vehicle are at risk when driving through water.

If you drive through water, have your automobile inspected by a reputable shop to identify and correct any issues. A lot of time and money will be saved in this way.

Examine The Interiors

Water can get into your car’s cabin and cause damage to the interior. Check for wetness in the carpet and other floor-level components.

Your car will require professional cleaning if it is moist. Due to the potential of mildew growth, simply letting the car to dry is insufficient.

Bad scents and poor air quality will follow if mold grows in the cabin. In addition to the risk of mold, moist components such as seat brackets are more prone to rust or malfunction.

Remove The Electronics And Disconnect The Battery

Disconnect the battery if you can’t start the car and the water level is high or rising.

If water gets into the electrical connectors or computer boxes, this will prevent dangerous electrical shorts.

You can try to save the computer box and stereo head unit if you know how to remove them and have the time.

Powertrain Control Modules located inside the engine compartment is usually watertight, whereas those located inside the cabin are not.

You’ll be able to remove these if you’re a skilled auto electrician or Modder.

Don’t bother if you don’t. However, it is preferable to err on the side of caution and save money.

There’s a reason why Acts of God coverage is included as standard in new insurance policies. If yours doesn’t, you might want to consider upgrading your policy.

Examine The Lights

Check for water damage on any external lights and indicators.

If damaged components cannot be cleaned or fixed, they will need to be replaced. Check to see if your car’s backup camera or parking sensors are working properly.

Check Your Brakes And Suspension Joints

Dirt and water can get into brake components, preventing them from working properly. This is why it’s important to have your brakes inspected by a technician.

Check for rust and lubrication in the suspension joints.

Examine The Vehicle’s Undercarriage

If you drive through muddy water, mud, grass, road debris, and dirt are likely to attach to the bottom of your automobile.

Make that the engine compartment; radiator, undercarriage, and bumpers are all in good working order.

If any part has dirt on it, clean it as quickly as possible. When damp dirt adheres to metallic components, it can lead to corrosion and costly repairs.

Examine Your Air Filter

It is necessary to replace the air filter if it is moist or displays evidence of dampness. It’s possible that you’ll need to change your engine oil as well.

To Rule Out Contamination, Examine The Fluids

Deep water can reach the engine compartment and pollute key fluids such as engine oil, transmission oil, and differential fluid if you drive through it.

Check the condition of the fluids with the dipsticks. Contamination has most likely happened if anything appears diluted, discolored, or milky.

Call your garage and have your vehicle towed in for a check if you suspect fluid contamination. Using tainted fluids in a car might result in serious engine damage.


If you can’t get the car back, the current is too strong, or the water level is rising, get yourself and your passengers to higher land.

If you have any doubts about your ability to do any of the other actions listed below, go ahead and do it anyway. When in doubt, like I already stated, don’t.

If you have no doubts despite having no off-roading or flood-driving experience, there’s something drastically wrong with you.

Always be cautious, whether the water is five feet or five inches deep, and whether you’re in a car or on foot. It’s possible that being extra cautious will save your life.

How To Restart The Car After Stalling In Water?

Water cannot be compressed, resulting in harm. If this happens, try removing the spark plugs and turning the engine by hand to get the water out of the pistons, then use the starter to crank it faster.

Car Shut Off While Driving Through Water?

If water seeps into your car’s air intake system and then into the fuel system, it can change the air/fuel ratio, reducing engine output.

This is referred to as hydrolock, and it can force the engine to stall.


So, What To Do If Your Car Stalls In Water?

When a car stalls in water, the most important thing to remember is to remain cool and secure.

Depending on the situation, you might be able to re-start the automobile if you’re handy and have the necessary tools.

Water in the cylinders and wet spark plugs can both be removed. Simply replace the spark plugs after that.

Another alternative is to push the car out of the puddle and wait for the electrical systems to dry out on the dry ground.

If that doesn’t work, you’ll almost certainly need to hire a tow truck. It’s a pain, but it’s something that comes with wet days.

If the Engine Damage Is Caused By Water Compression, try pumping oil to get some compression.

Severe engine damage, on the other hand, will almost certainly necessitate the services of a mechanic.

Frequently Asked Questions

What happens if your automobile stalls in a puddle?

When a car stalls or runs poorly after being submerged in water, Gower recommends inspecting, cleaning, and drying it off. Water gets sucked through the exhaust and into the engine if a driver stops or idles with the tailpipe underwater, according to Gower. It’s also possible for it to come in through the air intake.

If your car gets stuck in a puddle, what should you do?

Here’s some guidance:
If you’re stuck, keep your cool.
Don’t start the vehicle.
Put the car in neutral and push it to the shoulder lane if you’re powerful.
Think yourself lucky if your car starts, even if the engine light is on.

Will my automobile be okay if I drive through a puddle?

Water from the intake system eventually makes its way into the cylinders, where pistons compress the air. Water, on the other hand, does not compress, and the resulting pressure inside the engine can cause piston rods to bend or the engine block to shatter. Either way, the engine is effectively ruined.

Will my automobile start after it has been submerged in water?

When a car stalls in water, the most important thing to remember is to remain cool and secure. Depending on the situation, you might be able to re-start the automobile if you’re handy and have the necessary tools. Water in the cylinders and wet spark plugs can both be removed.

Do you prefer to drive quickly or slowly through water?

Slow down when driving. The last thing you want to do is speed down a flooded road. If you must cross the water on the road, do so at 1-2 mph and then drive at 3-4 mph to avoid flooding your engine.

Is it possible for flooding to damage your vehicle?

Flood damage can wreak havoc on a vehicle in a variety of ways, from corroding wiring to freezing mechanical systems. Driving across flooded roadways can harm a vehicle’s engine, deform brake rotors, disable power steering, and cause electrical components to short circuit.
