What Is The Liquid That Comes Out My Exhaust?


Normally the water goes out the exhaust as a vapor, but it can condense into a liquid if the surface or environment of the exhaust is cold enough. It is a byproduct of the combustion process, and that liquid is water. In simple terms, it is composed of chemicals such as Hydrocarbon fuel + oxygen = carbon dioxide + water.

Is it safe to drive with a leaking exhaust?

Your vehicle’s exhaust system keeps the car quiet and the exhaust fumes away from the cabin. Furthermore, the system helps to keep the engine running properly, reduce emissions, and provide you with optimum fuel efficiency. Driving with an exhaust leak is potentially dangerous as the fumes contain carbon monoxide.

Why does my exhaust sound like it has water in it?

It’s just how combustion works. Normally, driving around pushes enough hot exhaust through the system to keep everything warm, all the way to the end of the tailpipes. Because the piping is warm, the water vapor stays in a vapor state and doesn’t condense into liquid.

What happens if you don’t fix an exhaust leak?

An exhaust leak can cause dangerous gases to enter the atmosphere before being properly treated, which can cause problems like fumes in the cabin and failed emissions inspections. Many of these harmful gases are odorless, which means that you won’t realize they are leaking into the passenger cabin.

    Can an exhaust leak cause your car to overheat?

    Hot exhaust gases can leak into the cooling system, or coolant can leak into the cylinders and be burned off as steam, either way, the end result is an overheating engine.

    Can an exhaust leak cause poor acceleration?

    An engine runs optimally when exhaust flow is uninterrupted. An exhaust leak causes a drop in back pressure, which can lead to a decrease in power and sluggish acceleration.

    Can a catalytic converter leak water?

    In most times having water dripping from the catalytic converter is normal. The catalytic converter reduces the amount of vapor before it comes out from the vehicle’s exhaust. The converter makes your vehicle environmentally friendly by reducing its harmful effect of air pollution caused by the release of smoke.

    Can a leaky exhaust affect gas mileage?

    Reduced Fuel Economy and Higher Emissions

    If your car’s exhaust has a leak, this will have an impact on the pressure in the exhaust system, reducing fuel economy and leading to higher emissions.

    How do I know if my exhaust needs replacing?

  • Fuel Efficiency.
  • Vibrations.
  • Engine Noise.
  • Rattling Noise.
  • Hissing/Popping Noise.

    How long do exhaust gaskets last?

    Generally, exhaust manifold gaskets are hardy items, often lasting well over 100,000 miles. A lack of engine maintenance and carbon buildup, however, can cause hot spots in the combustion chambers and exhaust ports.

    How expensive is an exhaust leak?

    While the cost for fixing an exhaust leak varies from $100-$400, at an average fee of $100 per hour for labor plus additional expenses for parts, exhaust system replacements can rack up a bill between $150 to almost $1200.

    Will an exhaust leak turn on check engine light?

    A very common issue that will trigger the check engine light is an exhaust leak. Which can decrease fuel efficiency, causing your engine to work harder? Since the oxygen sensor helps to dictate the proper air/fuel mix used by the engine, this leak will generally throw off the readings of the oxygen sensors.

    How much does it cost to fix exhaust manifold leak?
