I ran it about 5 times today for short periods trying to burp the system but there is still a sizeable pocket of air somewhere. If I put 30 PSI of pressure on the pressurized surge system it will push about a cup of coolant into the system, but only coolant comes back when the pressure is relieved. That's probably about 2 cups of air in there somewhere. I'll just keep trying to burp the system. Today I went and ran the system after removing the piece of stuck RTV. Coolant flow still seems anemic because the sides of the rad barely get warm. There was some flow, however. Coolant temp (measured at the outlet) would be120 at low RPM and quickly drop to 90 at higher RPM (4000) and go back up shortly after reducing RPM again. This says to me that the higher RPM was generating good coolant flow. I still need another surge tank to catch all the overflow.
