Sounds like the coolant tank crack deal. I had the same thing happen. I would first top off the coolant with the proper mixture. If this turns the blinking light out, that is a good thing it may be just low. Considering you have a puddle of coolant, I am leaning more towards the tank needing replacement.

This will set you back about 700 to 800 bucks with parts and labor.

Best of luck!
