OK... I replaced my fan clutch and now my temperature guage is broke...
In truth, I'd rather be lucky than good

.
Seriously, I had a buddy help me and we replaced the fan clutch. You're right Dave, PITA

. Anyway, this morning I headed for the Saturn plant in SpringHill, about 1 hour form the house. The ambient temp was about 85F. The car never got over 90C despite some.. uh... spirited driving.
When I got to SpingHill, it was lunchtime, so I locked the car with my spare key and let it idle while I went in and got a sandwich. I came back out and let it idle with the AC on COOL while I ate my lunch.
It never got over 100C. In fact, when moving at, say 30mph, it wanted to run at about 85C.
I left there about 4:00pm with the ambient temp about 92F. I drove it hard back to town and stopped for fuel when I got back. I shut off the car and fueled, restarted and entered stop and go local traffic for about 20 minutes. Never got over 100C

.
I think I am going to declare that the fan was the problem.
Thanks for all of the feedback. I will take the long grades next week, but I'm pretty confident. It's like a different car altogether!
