The exhaust system in your car works by getting rid of the byproducts that are created when your car is running. The byproducts are expelled through the tailpipe and you may find a little bit of water leaking out of the tailpipe. This typically isn’t a huge concern, it just means that there is a little bit of water in your exhaust system that needs to get out. Sometimes what you see could be more serious, so make sure you read this full article to help you determine if you need to get your car checked out by a professional.

Main Reasons for Water Dripping Out From the Exhaust:

  1. Engine Combustion and Water Condensation
    As combustion takes place in your vehicle’s engine whenever the vehicle starts, a mixture of water and carbon dioxide is formed. When the engine cools down completely and exhaust gasses exit the combustion chamber, condensation of water and carbon dioxide can be noticed much more, and in a moment like this, you notice water dripping from your car’s exhaust pipe. This is completely normal and you don't have to take your car to a professional.
  2. Catalytic Convertor Byproduct
    Catalytic converter plays a major role in reducing the pollutants that go into the environment. It transforms the byproducts of vehicles into substances that do not harm the environment. It converts the toxic waste products of the vehicle into non-harmful components as in water or gas form. Water dripping out from exhaust is an example of a catalytic convertor working at its best and this is not something that you should be worried about.
    Another issue specifically with catalytic converters is theft. In 2020 and 2021, the number of cases of catalytic converter theft has been rising dramatically. To learn more about catalytic converter theft and what you can do to protect yourself, click here!
  3. Condensation From Heat
    If your car is in a colder climate, it will need to warm up before it can work properly. This causes excess heat to be built up in your car and is later expelled through the tailpipe. That heat will produce condensation in your exhaust system, so you will see water droplets coming out of your tailpipe. This has the potential to be dangerous, but all you need to do is let the engine run for a few minutes before you start driving.
  4. Smoke and Water Emissions
    If you notice smoke and water coming out of your tailpipe, this could be a big warning sign that your pistons are not working properly. If the situation is a more serious one, you might also notice a burning smell or a sweet smell. This is very serious and you should get your vehicle checked out by one of Wrench’s mobile mechanics as soon as possible so we can keep your car safe and sound on the road.

Now that you know what kind of water from the exhaust pipe is serious and what is not, we hope that you can move on with your day with peace of mind.
