Appreciate the input on the thermstat, and I am inclined to think that this is not it since both the old and the new performed the same way - temps climb with slower speeds.
The vclutch - I can't tell you guys how many times I have felt the resistance when I spin the fan. I felt it with engine cold, engine hot. There is resistance to spinning the fan by hand in all cases. I even saw one post that stated that the spin down time should be 2-5 sec for a good vclutch. I had my better half (my wife let me buy this car in the first place!) turn off the key and timed the spin down and it meets the 2-5 sec test.
Again, the temps I observe now are hotter than before, but never exceed 110C on the gauge. I even added WW but that had no noticable effect.
Thanks for all of the correspondance and suggestions to date. I always save my good problems for this great group.
