No offense taken there, any question or comment is more than welcome. Yes the fan is installed correctly, when standing in front of it before the grill went in, my work shirt got sucked against the radiator.

The radiator has definetly crossed my mind. It sat empty for about 2 weeks before getting reinstalled. I was thinking of trying no thermostat, if it still does it i can eliminate t-stat, then looking into radiator, unless im encouraged otherwise.
Does this sound like a head/air in system problem? I know when we had the head gasket issue before it would overheat at any speed, even idling, and now its just at higher speeds. This is one of the most frustrating things ive ever experienced, and i would love nothing more than to be able to forget about this van for a while, i appreciate your replies, any more thoughts are more than welcome.
As far as timing, we had some timing issues right after initial startup and temps were raising at idle. We then adjusted timing to 10 degrees and the idle smoothed out huge and temps stayed normal. I dont get it, i can let it run for 3 hours outside in the driveway, but the minute im on the freeway, im toasted.
