Does you car steam?
Hey everyone, So I have a question for you all. Especially those of you who have a 7th Gen monte carlo. I just got mine a couple months ago, it is a 2006, and I never really payed to much attention to it except for the other day it was fairly cold out and I was letting my car warm up and it steamed a lot. I had a 96' thunderbird before my Monte and it didn't steam near as much as this. I'm sure it's normal but I'm just wondering if you guys run into the same thing.

You maybe just have a Super Hot Monte Carlo
The converter is basically not running at all for the first few minutes after the engine started since it is cold. The converter needs to heat up significantly (it can glow red in higher performance cars after a high speed run). To properly function. When you start an engine, it always runs rich (with more fuel) for a minute or so, and eventually the the mixture will lean out (less fuel). Once the cat reaches operating temps, the chemical reactions start taking place in full force, and one of the main products of those reactions is water vapor. And voila, that's how you get a steamy exhaust.
But since the cat is usually pretty close to the engine, after several minutes the whole exhaust pipe eventually heats up and "dries" up the air somewhat as it travels down the exhaust system. That is why it tends to reduce after it warms up.
