You are probably aware of the fact that when your car is running, it generally creates a lot of residues. The principal functionality of the exhaust system in your car is to eliminate those generated byproducts. Through the tailpipes, those byproducts are terminated from your car’s engine out in the environment.

However, in some cases, you can notice a small amount of water dripping out of the tailpipe. It clearly indicates that the exhaust system inside your vehicle has some water in it. Nevertheless, this is not actually an alarming sign because it is quite obvious.

But, as you know small issues lead to bigger complexities. Therefore, if you find out water coming out from the exhaust, make sure to keep a keen eye on it.

Before determining the solutions, you ought to understand the reason for this inconvenience. Once you detect the anomalies, finding the key will not be a big deal.

Reasons Why Water Coming Out From Exhaust

There is more than one reason behind the occurrence of this catastrophe. If you are willing to know the reasons why water dripping water from the exhaust, continue reading.

1. Condensation

Engine combustion is the most common cause of water dripping. When you start your car, combustion crops inside the engine. As a result, a mixture of water vapor, carbon dioxide, and nitrogen is formed.

When your car’s engine finally cools down and the exhaust gases drain out, you can notice the condensation of water and carbon dioxide. Afterward, you might even see a little water coming out of the exhaust when starting car again.

But, this is nothing serious. Hence, you neither need to be worried about this issue nor take your car to the professionals.

2. Engine Heat

The engine of your car produces the maximum amount of heat as soon as you start it. The lubricants in your car engine require a substantial period of time to grease and flow through the parts of your vehicle to make them cool down.

However, if the car engine is still heated, then its exhaust system will remain hot as well. It will in turn create water vapors inside your car’s exhaust system.

Now, it solely depends on the weather condition that how much water vapor will be formed. The cooler the environment is the more water droplets it will produce.

Thus, you can notice a few drops of water, leaking from the tailpipe of your car. Alongside this, you can observe some white smoke as well.

However, both the smoke and the water droplets are more likely to be cleared up. If it does not, then, you perhaps need to fix the leakage matter as quickly as possible.

3. Catalytic Converter

Another aspect that can make water coming from the exhaust is the catalytic converter.

This component acts in lowering the number of noxious gases that are usually emitted from the exhaust system of your vehicle.

This specific part of your car ensures that the lethal gases do not mix with the air, making your car friendly towards the environment.

However, while the catalytic converter works in reducing the toxic emissions, a little amount of water vapor is generated. Eventually, the water vapor creates small droplets of water, which are discharged out of the tailpipe.

If this whole water dripping issue fades away within a few minutes like earlier mentioned, then consider it as normal. However, if the car exhaust dripping water is constant, there might be some other leakage issuances.

4. Failure of Gasket

The above-mentioned reasons are usually out of concern as in those cases the water leakage stops within a few minutes. But, if you find out that the causes of water drip from the exhaust are due to malfunctioned head gaskets, then it is a matter to worry.

Blown out head gaskets are responsible for emerging white smoke and water from the tailpipe. In fact, you can even detect overheating issues and bubbling of air in the coolant tank.

If you left the condition untreated, the results will be terrible. It can even leave you stranded in the middle of your journey.

5. Faulty Rings or Piston

Apart from the gasket failure, there is one more reason that you need to be bothered about. A faulty piston can cause lots of water coming out of the exhaust. To repair or replace it, you might need to spend a significant amount on its servicing.

If your car piston is in a really bad condition, you would sense a strange burning smell from the inner part of the cabin.

If you come across these signs, it would be better not to ride it. Otherwise, you might get indulged in severe troubles.

How to Fix Water Dripping Problem from Exhaust

Now, you all are aware of the potential reasons why water coming out from car exhaust. After diagnosing the fault, it is time for you to take some initiatives to fix up the issue.

If you have read the post this far, you already know that the reasons for water leakage can be classified into two categories: major and minor.

For Repairing the Major Issues

For the major cases like faulty piston or gaskets, it will be hard for you to fix the matter without expert guidance.

In that case, the only way of ceasing the water coming from the exhaust is by replacing the malfunctioned components with new parts.

For repairing the Minor Issues

On the other side, if a minor exhaust leakage is responsible for the inconvenience, you can avail of the below-enlisted methods to fix up the matter on your own.

Method #1 – Detection of the exhaust leak

The first and foremost thing that you need to do for repairing the water dripping out of exhaust pipe is to find out the root of the issue.

  1. At first, you ought to jack up your car. Well, you can make use of the floor jack to accomplish the task easily.
  2. Once you raised your car off the land, make sure to secure it with jack stands.
  3. Now, you will get enough space to move around your car and find out the leak spot.
  4. Before inspecting the leakage, allow the exhaust to be cooled down.
  5. If you are incapable of finding out the exhaust leak even after a thorough inspection, you can ask any friend to start the car.
  6. At that time keep a sharp eye on the exhaust to point out the source of leakage.

Method #2 – Seal the Leakage with Exhaust Tape or Repair Epoxy

After identifying the source wherefrom water coming out from the exhaust, clean the enclosing area with a toothed brush. Doing this will clear all the mud and dirt. Unless you clear the rust from the surface, you cannot stick the seal or tape over the leakage.

If the toothed brush alone cannot clear the area, you can use the sandpapers. It will not only clean up the last trace of dirt but also generate micro scrapes in the metallic components to help fix the epoxy or tape precisely.

To remove the last bit of rust, you might utilize the acetone. When you are done with all these pre-procedures, focus on the size of the leakage.

If it is a small hole, you can just put the exhaust tape or epoxy over it. However, if the leakage is a bit larger, you would probably need a patch to fix it.

Method #3 – Using a Patch

Similar to the exhaust tapes, exhaust patch kits are also available in the market. But, before you invest money, do not forget to consider the size of the patch that you would need to fix the hole or leakage. However, if you find the patch kits a way more pricy, you can prepare your DIY patch kit.

For that, you need to cut aluminum can measuring the size of the holes. Always keep the patch half-inch bigger than the hole. After that, apply the epoxy on the patch and place it on the leakage area. For ensuring a tight seal, secure the patch, using two hose clamps on each side of the hole.

After fixing the exhaust system, you should always run a test drive to ensure that the system is up to the mark. The signs of a healthy exhaust system of a car include the smooth sound of the engine, clear smoke emission from the tailpipe, and most importantly, no longer dripping of water from it.

If everything looks perfect, you can be assured of the accomplishment of the repair.
