Overheating on the highway with normal EGT's

Overheating on the highway with normal EGT's
Well, I'm not towing anything, the air temp is hot, but not even 90*. Turn onto the highway after being stuck in traffic. Turn on the A/C, look down and sure enough I'm at about 200-210*, hot for what the truck normally runs at 190*. Now, its idled rough for a while, I got new injectors today as a matter of fact. Everything looks and runs like normal, but the temp is high. I pulled off at one rest stop and let it cool down a little bit, popped the rad cap and it puked a little fluid (greenish brown, I know I gotta change it but thats clearly not the problem alone). I filled the reserve bottle with water, all I had at the time, and all the way home, 2.5 hours, it ran just over 190, occasionally dipping down to 190, other times hitting 200 or so.
Here's my plan of attack:
Flush the coolant and throw whatever cleaner I can find in there.
Power wash the radiator in the truck, with the intercooler and everything still in (bad idea?)
Replace the thermostat (it was replaced about a year ago)
Do whatever you fella's recommend if it seems logical...
So what ideas have ya got? And do you all agree that its a cooling system problem, not an engine problem?

There is a good chance the oil puke bottle on the front of the engine has finally plugged up enough of the radiator and its not getting good airflow though it. The only way to throughly clean it is to remove the radiator from the truck and powerwash it. Taking the radiator out really isn't that big of a deal, takes all of 20 minutes.
