When its cold outside and you start your car, there is always a steam vapor in the exhaust, until the car gets hot, then it is usually gone. Well even after my engine it hot, i still have the steam vapor coming out of the exhaust. Exhaust doesn't smell like coolant, and the coolant isn't low. Anyone have an idea as to why i still get vapor well after the car is hot? Is this normal?

Mine does the same thing, I always wondered why...and I know I'm not burning anything (fluids are always full, and never drop). I'm thinking it might be something with my catalytic converter, because it's still original...unlike the rest of my exhaust. But then again, I don't know.

If I remeber right from chem, doesn't combustion produce water vapor as a byproduct? Someone correct me if I'm wrong.

But the cat is supposed to light off the moisture, it just seems that there is too much moisture for too long.

It means your hot air is creating steam in the high humidity. It's common. No worries.

However I see that you live in florida!

So yea perhaps my knowledge isn't needed!
