fluid comming out of tail pipe...

Postby mrreilly » Tue Sep 19, 2006 9:29 pm

Today my friend who was following me said he saw some fluid comming out of my tail pipe. He would see it after i started going from a standstill. It's not much of whatever it is, but is/could this be a bad thing?

Have you noticed any drop in coolant level?

How hot was the engine when your friend saw the fluid?

At start-up it is not unusual for water vapour to condense in the exhaust system and come out of the tail pipe in a fluid state. This is usually more noticeable in cooler weather conditions but can be seen when the engine is still running under normal operating temperature.

The fluid is fine, staying stedy since I got it. And then engine temp is normal.
From what you said in about the water vapor forming, that's sounds like it could be it. It is starting to cool down, and i think when he saw the fluid coming out, it was after i started my car.
I'll keep and eye on the fluid levels for a while just in case though.

Water vapor is a by-product of the combustion process and will condense in the exhaust system if the system is cold. If you make a lot of short runs, especially in the Winter, the exhaust system will fill up with water and when you first start the car and head up the street it water will run out of the exhaust. Perfectly normal.

If it were antifreeze leaking into a combustion chamber you would have billows of white smoke out the exhaust and your engine would sieze up if driven that way for more than a few weeks.
