Water Pump Failure in Seattle!

[daveola]

1) There is an overtemp shutoff and I know it works from when I first got the bus and Mike Kadletz thought it would be clever to run the bus with the solenoid to the fan belt turned off.
2) How do you bleed the tstats (and I know where one is by the pump, where is the second?)
3) I think this is the big bore pump since they had found the small bore pump and didn't want to use it.  Is there a way to tell?  The pump is the same size on the exterior.
