water pump/ advice

[Jim Strickland <ihaveanaccount@xxxx>]

I recently found that my machine had totally run out of water/coolant....
I filled up the water to full (a few times, as each time I started the
machine up the level went down again). Then I put it on level ground and
opened the bleeder valve to get the remaining air out... Nothing came
out. I'm a little perplexed, becuase I did a bleeding a few months ago
and everything seemed to be working fine at that time. 

Can I assume that my water pump is not circulating water??? The pulley
is definitely TURNING on the outside, at least. What else might cause
this lack of bleeding problem? I'd figure that it'd bleed off extra
fluid when the overflow tank was full to the brim... is this not so?

Jim.
