I've noticed the faint smell of coolant whenever I get out of my car. I can also smell it while idling with the windows down. I don't notice any smoke/steam, but it's strong enough to smell it.
My vehicle is not overheating - the temperature gauge sits right where it always has - but something is leaking and forming a small puddle when I park for a few hours.
The liquid that's leaking is clear. I've never put coolant in my vehicle, so I'm not sure if this is actually coolant. (Isn't coolant orange or green?) Also, I dipped my fingers in the fluid and smelled it, and it doesn't have that sweet/fishy smell that coolant has. It leaks from the middle of the area between the two front wheels, if that helps.
