That means...

1. Bad Water Pump....Don't see how this would be the problem, but my temps are fine and water pump seems fine.
2. Heater Core Leaking...Possible
3. Hoses Leaking (either constant or return... check both!)....Pretty sure IACV, throttle body, turbo lines, and radiator lines are all fine.
4. Water Outlet @ Top of Block (feeding to radiator)...I'm pretty sure this is fine.
5. Leaking Radiator....Didn't check this, but it's possible I guess.
6. Coolant Reservoir Tank should be connected....Is connected.
7. Coolant Reservoir Tank might have a crack in it

....Good point, will check this.
