Hello,
i was worrying about my AC until my attention has been rightfully diverted. I walked back to my car after it was sitting for about 10 minutes after a 50 minute drive to see coolant rapidly dripping under the car. I pulled up the hood to see:

The overfil bottle was maxed out and coolant was being squeezed out of the overfill hose joint! When I start the car, it sucks some coolant back into the system and the coolant goes down to the "max" line. Slowly, as the car sits off but is still very hot, the coolant goes up in the overfill tank.

Did I blow my headgasket? The car is running fine... and I didn't see any obvious signs of water/coolant on my dipstick, but i haven't drained the oil yet.

Thanks,
Rick
