Answer
Hi John -

As you can imagine, it is very difficult for me to accurately tell you where the coolant is leaking from without being physically there to probe around. Can you give me more information, like what area of the floor do you see this coolant - front center, front right or left, towards the middle of the car? Have you taken a pressure test? How often, if any do you have to refill with coolant? When you say it is leaking antifreeze when you start the car, does this mean the puddle is already on the ground, or do you see it dripping as the car runs?

Please get back to me -
aloha
