coolant questions

ok today I started up my car and drove it to the store down the street, the last time I drove it was a week ago and I noticed that some fluid had leaked out on the garage floor. After closer inspection I noticed that it was coolant that somehow has leaked out? somewhere in the front of the engine between the middle of the car and the right headlight and I looked at the coolant level in the tank and noticed that it was low. Where can I pick up more coolant and what might be wrong? I have no check engine lights at all.

Jack it up and check the hoses. Get coolant from the dealer.

You won't get a CEL. You'll see the coolant temp gauge rise once it runs real low though, which is very bad.

ok well I took a look at it this weekend and it turns out that it was the windshield washer tank that was leaking out of a small grommet in the front, not the coolant. I pushed the plug back in and I guess it stopped it but that weird that the grommet poped out. Anyone have any ideas as to why it would happen?
