Modern vehicles are equipped with catalytic converters. Catalytic converters use heat and oxygen to strip atoms off of exhaust gas molecules. Nitrides of oxygen a.k.a N20 are separated into nitrogen and oxygen molecules, hydrocarbons a.k.a HC3 are stripped into hydrogen and carbon molecules the heat combined with the presence of hydrogen and oxygen causes the two to combine in to a new molecule H2O a.k.a water. A little water from your exhaust system is actually a good thing, it means your catalytic converter is performing properly.

Check out howstuffworks.com to see how a catalytic converter uses heavy metals like platinum and paladium and the heat from the exhaust to do this, it's pretty cool.

Now you can impress your friends with some useless fact ;)

For some reason the gas is not completely combusting causing water to be expelled in the exhaust pipe.


What does water coming from exhaust pipe mean?

Not much. When the exhaust pipe is cold, water vapor will condense as the exhaust cools on the pipe. After the pipe heats up, the vapor will not condense. Remember that the combustion of hydrocarbon fuel produces both carbon dioxide AND water vapor as a normal part of the process. All gasoline engines produce water vapor and all water vapor condenses if the exhaust pipe is cool.


What does it mean when water comes out the exhaust pipe of my impala?

Water comes out of all tailpipes no matter how minimal. The combustion reaction of burning gasoline (C8H18) and oxygen (02) produces carbon exhaust (Cx) and water (h20) thus leaving water in your tailpipe. Water can also appear in an exhaust pipe due to condensation. Water in an exhaust pipe is perfectly normal and is of no harm to your vehicle, or any vehicle.

Why is water dripping from my furnace exhaust pipe?

Water dripping from your furnace exhaust pipe could be a sign of condensation buildup. When the hot exhaust gases from the furnace come into contact with the cold air outside, it can cause moisture to form and drip from the pipe. This is a common occurrence and usually not a cause for concern. However, if you notice a significant amount of water or if it is accompanied by other issues like a blockage in the pipe, it may be a good idea to have a professional inspect and address the problem.
