After doing some research on a couple of vehicles, I've come up with a few things:
1. The gauges stink, and read hot when they really aren't. Invest in either one of the stickers for the radiator, or hide a real temp gauge. (Courtesy of Walt Knuckels)
2. The 6 blade fan works great, BUT has to be positioned properly...the blades should not be completely inside of the fan shroud. Most folks have it too far forward. (Thanks again, Walt)
3. The lower shroud and 4 row radiator help a lot.
Mine is an automatic, spending time in TX, GA, and FL, and doesn't overheat. The gauge said it did, which scared the heck out of me. Then again, it doesn't leak, either.
