Okay guys just thought I would provide an update. Before I get started,once again let me thank everyone for the assistance.

1) As suggested verified cap was fastened properly. Went all the way to last notch, no change, but good suggestion.
2) Once car cooled thought I would check New Delco cap 6410962 (Rock Auto)and with pressure tester. New cap would not make it to 17psi as stated on cap. Failed before 15psi
3) Went to Autozone and purchased Duralast 7716, and check with pressure gage. Cap held 16 plus psi.
4) Installed new Duralast cap and started car. Coolant pipes temp changed within 90 seconds but was warm within 150seconds.
5) As suggested verified temp with HVAC controller. Car achieved temp of 102C and fan kicked on as it should. Fan stop running when temp reached 98C. Note, in previous attempts by this time coolant was flowing past radiator cap and analog gauge was well past midpoint.
6) However, with the Duralast cap installed, I noticed coolant leaking around Brass filler neck and the seam of the tank.

In summary it appears my New cap faulty which masked a leak in the plastic tank. Will replace tank and go from there. After a year and 4 months, one day soon I will drive this car.��
