Funny side note. I bought an 08 Caravan 2 months ago and when the salesman opened the hood, I told him I wanted to see how easy it was to change the radiator out. The last 3 used cars I have owned have needed a replacement radiator. My wife's 05 Equinox was the absolute worst one to change. The dealer gets around $600 labor for it and I found out why when I changed it. There is a pretty good place to get radiators cheap on Ebay called Automotive Cooling. They are about half the parts store price and ship pretty fast.
