Water out tailpipe?
Hello, the other day I noticed some water dripping out my tailpipe. I checked the water levels and everything seemed normal.
I think it rained the night before but the drips were pretty constant.
Should I be worried or is there anything I can do or is this normal?

Anyway, what is that from? Where does the water? come from?

no when you burn fuel (a hydrocarbon) the hydrogens bond with the oxygens to make a good bit of water. H2O and carbon are the main byproducts of combustion. Your AC has NOTHING to do with what comes out of your exhaust

a little bit of water coming out is like.... your engine is healthy, as bgoetz said, COMPLETE combustion..... which is a good thing.

dont ever question or doubt anything i say....

??? Thats the funniest thing I've ever heard, maybe if the car used hydrogen fuel, but not gasoline. The water dripping from your tail pipe is condensation. Burnt fosil fuels might leave a trace of H2O but not enough to notice.

and just to back up my point think of it this way. The first law of thermodynamics states that energy is neither created or destroyed. So all of the components of fuel exit the vehicle through the exhaust pipe only in a relativly inert form. Hydrogen gas is unstable on its own this is why there are only a few different ways to create pure hydrogen gas (electrolisis ect.). There for the Hydrogen molecules that are broken from the carbon bond via energy is quick to bond to a Oxygen molecule (the simplest thing to bond to) this makes H2O water my friend that exits you exhaust pipe. So unless you are going to say that hydrogen builds up inside your engine or that it exits as mostly pure hydrogen (in which case there would be a way to collect the valuable gas) then you are WRONG.

I'm an engineer and know exactly what you're talking about bgoetz.
We can actually figure out how much water per engine "putt." Just figure out how much fuel is there, how much air, and you have a basic chemical reaction to figure out.

^^^^ yep, I am really not an A$$ I just don't like people that think they know everything, but could not be further from the truth. I use to know how to figure it out too, but to tell you the truth I honestly forget how many Hydrogens are in the molecular structure of unleaded fuel.

Rep Power: 0 Chemist or not, the water coming out the tailpipe is condensation, I'm not saying that you're wrong about fuel leaving behind water, but the water out of a cars tailpipe is condensation, plain and simple. Any water left behind from burnt fuel would vaporize from the hot exhaust pipe, so after you park your hot car and it starts to cool down, water from the outside ambient air will condense inside your exhaust and muffler, just like the water condensing inside your windshield in the morning, or is the condensation on my windshield caused from fuel also?
Plus if your statement were true, then why doesn't water come out your tailpipe everyday? It only happens when high humidity and low temperatures are present.
Also I'm not an idiot, so get off your high "I'm such a smart chemist" horse and get some common sence.

Rep Power: 0 No, it comes out of the exhaust ALL THE TIME. You just can't see it because of the temperature of the exhaust. Yes, when you see water dripping out, that is condensation, as the water condenses on the sides of the pipe, and then runs out of the muffler.
Water on your windsheild has nothing to do with fuel.
CH4 + 2 O2 --> CO2 + 2 H2O
This is the chemical equation for methane burning in an excess of oxygen. This produces carbon dioxide (CO2) and water (H2O). Note that there is a (2) in front of the H2O, designating that for ever (1) mole of methane burned, 2 moles of water are formed, and only 1 mole of CO2.

yep H2O is H2O in vapor, liquid, or solid form it is still H2O.

No you are sooooo wrong. Water from the OUTSIDE AMBIENT air. It is water that is in vapor form from burnt fuel and cools and condenses on the inside of the exhaust. I am not on any high chemist horse, the fact is that I am not even a chemist. However I do have a degree in the science field and took alot of chemistry. I just don't like it when people that are obviously less intellegent on a issue try to argue with me and are dead wrong. If you don't believe me ask a chemistry teacher. The only thing the Ambient air has to do with it is to cool the exhaust no vapor fairies fly inside of you exhaust from the air and deposit water
No you are sooooo wrong.
