Afraid of the answer.....

Water can be pouring out from a crack in the overflow tank. Otherwise you'd have some coolant too.

Find out what's wrong. May be simple stuff.

Thanks.
I did have the coolant tank replaced about a month ago.
When I did some poking around today I saw a broken thin metal pipe that is covered in rubber on the top of the engine. It looks like it came from the coolant bottle.
I also saw a broken hose that I think is a different one that has one of those weird connectors like on the AOS hoses. Both of these are roughly in the same place on the top of the engine near the AOS. I'll go take some photos.

The pulley from the alternator is GONE.
That's what failed.

The real question to me is did I cook the engine? Are the heads warped, cylinders cracked, etc?
