[Overdrive]

Aw, man...this is not what I wanted to see first thing in the morning. Sorry to hear, man.

My mind was trying to fly through the possibilities of what's up...water pump failure, maybe? Maybe some impeller pieces got stuck in some of the cooling channels and blocked your coolant flow. Is there any fluid on the ground under the car?

The only other thing I'm thinking, since you mentioned running the A/C, is that the radiator fans may not be functioning.

Please let us know what you find. Hopefully there isn't any serious damage.
