(that way if I caused a leak with replacing the t-stat I would know it was my fault).

yes, at 110* outside, I run the A/C. I go to end user sites often, and I cannot be sweaty/stinky. but turning off the a/c doesn't seem to make a difference unless i turn on the heat.

Ok, so the fans seems to be ok, as these provide the cooling in slow speed traffic (city, stop & go).
If it get hot while faster driving, it points a bit towards the radiator or airflow itself. For higher speeds fans are irrelevant and even get bypassed by flaps in the shroud (on some cars).
What we could do is check temps at the radiator inlet and outlet, under different conditions.

Something else you could check, if it really holds the pressure for a day or so. Pressure rating is on the cap, just keep it a tad below and see if it gets less after a day, as it could also leak into the cylinders slightly.
