Fluid coming out of exhaust...

[crazie.eddie]

I don't have this problem, but I remembered seeing a car in front of me that appeared to have some kind of fluid coming out of his exhaust. I also remembered seeing a PT with fluid coming out of it's exhaust as well, a few months back. I was just wondering if this is a major problem or just something normal. I know to watch out for oil, trans fluid, coolant leaks and kind of know the area to look at them for. Also I know water leaks from condensation due to the airconditioning being on is normal. But I was curious about any clear fluid coming out of the exhaust. Since it isn't happening on my PT, I can't examine if the fluid has any kind of smell or anything.

It's normal,just condensation being blown out.

agree it's normal.

Cool. I guess if it was happening to my car, being just condensation, it had probably dried up, before I could really notice.

Now is this condensation from the engine itself or the condensation from the airconditioning working itself way through the exhaust? If someone could give me a more technical info as why this is happening so I could be more knowledgeable, I would greatly appreciate it.

A/C condensation comes out up front, I beleive it's on the passenger side from the evaporator,works the same as in your house.I beleive
the water coming out of you tailpipe is condensation that is built
up in your muffler as it cools down and pulls the moisture out of the air.I could be way off, I'm sure someone on here will correct me if I am.

Jimbo is right on. Once exhaust is warmed up, shouldn't see it any more.

When gasoline (HC) is burned 'perfectly' it is oxidized. Chemically, that means H2O and CO2 are produced. H2O is water. It will come out the tailpipe as steam, unless the air temp and the pipe is cool enough to condense it back to water. You will see it on cold days when the car is first started. Look closely and you will see drain holes on the rear bottom of mufflers to allow this to drain.

Spot on. Eddie, I'm sure on colder days you've seen "smoke" coming out the tailpipe of several cars. It isn't smoke, but the steam purple04 mentioned.

Just to add, the exception is for riced civics. The liquid dripping from those tailpipes is usually... well, since the exercise wheel in the engine is higher than the downpipe and exhaust system, hamster pee drains down the downpipe and out through the exhaust.
