Took some temp measurements on the radiator. At the top near the upper hose I measured 192 degrees and at the lower hose I got 158 degrees. So that should prove the radiator is flowing well. I started it @ 6:39 with the outside air temp of 96 deg and after 21 minutues of idling and slow 20 mph cruise for about 2 block in the neighborhood and back to the driveway for more idling it finally reached 195 deg on the temp guage. This is pretty much the scenario but it would have climbed to 220 had I let it sit running a little longer. The problem is that it just does not cool itself and hold a steady temp. If I were idling in stop and go traffic and then a run down the freeway and back to stop and go traffic it just will not hold a good temp. I cool it down by parking it and let it sit. The search continues as I will be trying some of the other things you guy have mentioned in this thread.
