[DeTomaso] Recap... Asa's adventure in Pantera fluid dynamics

I don't believe that a large pocket of air got "stuck" at the pump. You had 
a hole drilled in the stat and the system was clearly filled with coolant. 
The coolant was not flowing through the system.
Do you have a drain petcock at the top of the rad?
