How To Get Water Out Of Your Exhaust? Explained in Details

During the internal combustion process, exhaust gas emission occurs within the engine. The engine must get rid of all the gasses inside it because it’s harmful to the engine and would cause damage to its internal parts.

Water dripping out of the exhaust pipe is a very normal thing. It’s because you’re burning Hydrocarbons in the existence of the Oxygen available in the atmosphere. So, they naturally form water.

The most efficient method of getting water out of the exhaust pipe is using a car dryer. You have to hold the dryer, and the hot and dry air from the dryer will automatically dry the entire exhaust pipe and stop the dripping.

Sometimes you’ll notice water dripping out of the exhaust pipe. It mainly occurs because of the condensation of those exhaust gasses. That’s why you shouldn’t panic if this happens to your car, as it’s completely natural. But it’s better for you if you know how to get water out of your exhaust pipe.

Common Causes Of Water Entering The Exhaust System

The bi-product of the internal combustion process is water. There are numerous reasons for this water entering the exhaust system. Here are some of the common causes:

Engine Water Condensation

When the engine goes through the combustion process, various bi-products form up. The major products are vaporized water, carbon dioxide, and nitrogen.

Water and carbon dioxide get mixed as the exhaust gas goes out of the pipe. And when the engine cools down, water starts to condensate as well. After that, it forms into liquid and drips out the tube.

However, it would be best if you didn’t have to worry about anything as it’s a pretty normal reaction, and it happens all the time. The dripping stops after some time once the exhaust pipe warms up.

Driving Through Flooded Roads

If you’re driving through the country roads during the rainy season, there’s a chance that you’ll find the water coming out of your exhaust pipe.

When you drive through flooded roads, the water gets the chance to get inside your exhaust pipe. As the tube is located at the bottom of the car, it’s not surprising how easy it is for the water to get inside.

Even if you drive at a slow speed, some water will enter the exhaust pipe as it sits under your car. So, it’s better to avoid going on these roads during this season.

Head Gasket Failure

If blown out head gasket causes water leakage from your exhaust, you should worry the most.

You’ll notice air bubbles forming inside the coolant reservoir, and there’ll be some heating issues. Moreover, you can identify something’s wrong with the head gasket because you’ll see white smoke coming out of the tailpipe.

This issue should be addressed immediately and not be delayed for any reason.

During Carwash

Water can also enter the exhaust system during a carwash.

If you’re not careful during carwash, there’s a chance that water will get inside the exhaust system through the tailpipe. It would help if you were extra cautious of this as it can even cause engine failure.

If you use something to cover the tailpipe tip, you can avoid getting in trouble so water doesn’t get in.

Easy Methods For Getting Water Out Of Your Exhaust:

There are many methods of getting water out of the exhaust pipe. The most useful of them is using a car dryer to dry out the liquid. Another excellent technique is to punch a hole in the exhaust pipe. Both of these methods work perfectly, although they are used in different cases.

Using A Car Dryer

If your exhaust pipe is continuously dripping water, you can use the car dryer.

It usually occurs if the weather is too cold – the water vapor in the exhaust cools down and turns into liquid. So, the dryer helps reheat the water and vaporize it. This gets rid of the dripping water issue.

The best thing about using car blowers is that your hands won’t need to get dirty! A car dryer can reach out much further than you can anticipate and get rid of the water for you.

Making A Hole In The Exhaust Pipe

This method will work only if your exhaust pipe is filled with water. This problem can occur if you drive through flooded roads or are not careful during a car wash. Your engine will suffer the most and can even malfunction in both cases.

Try punching a hole a few inches away from the tip of the exhaust pipe, and you’ll see the water quickly pour out.

How To Prevent Water From Entering The Exhaust System In The First Place?

To prevent exhaust system problems, you should have it inspected at least twice a year. This is undoubtedly the best practice regardless of whether there’s any problem.

Schedule a service with an expert today and let the certified technicians care for your vehicle. They’ll take one look at your car and tell you what’s wrong with it. They’ll quickly identify the problem and can provide a satisfactory solution.

Common Fixes For Getting Water Out Of The Exhaust System

The most common cause of finding water in the tailpipe is condensation. And the most common fix for this is keeping the engine on for a while.

Heating the engine will heat the engine and ensure that the entire exhaust system is heated. The water forming in the tailpipe will automatically vaporize, and the dripping will stop when you do so.

If the water dripping still doesn’t stop, consult a technician as he’ll know exactly what’s wrong with your vehicle and give you a solution.

Tips & Tricks To Clean And Maintain Your Exhaust System:

Properly maintaining your vehicle is a must if you want it to serve you longer. You should frequently clean and check for problems. Regular check-ups will ensure that your car will be in the best condition and ready to use.

Here are some tips & tricks that’ll help you clean and maintain your exhaust system:

  • Go to the exhaust pipe only after you’re done cleaning the wheels
  • Clean the end of the exhaust pipe with a separate brush
  • You can use steel wool and scrub the edges with it too
  • Try using a microfiber towel if steel wool doesn’t do the job
  • Use an exhaust cleaner to clean the external part of the pipe
  • Make sure to dry the tips after you’re finished cleaning


Most of the reasons that cause water formation in the exhaust pipe are water vapor. If the weather is cold, then the heat exerting from the tailpipe will naturally condensate and turn into liquid.

You can’t actually stop the reaction from happening. What you can do is learn how to get water out of your exhaust system and be prepared for it. So, drive carefully and avoid driving through flooded roads as it’ll eventually harm your vehicle and reduce its performance!
