I was driving my car a week ago and to my surprise the "low coolant" thing lit up on the dash so I topped it off and it went away, about a week later it came on again. I knew something had to be up, when I got home I decided to look around. When I look down into the engine, on that cover that covers the bottom of the engine there is coolant there. I can hear it dripping, but can see where it's coming from. The car runs fine and smooth as usual, no check engine light either...any suggestions?
The car has 90k miles on it.

I took a pic this morning and saw a lil pool of coolant just under the water pump area...
