Re: I6 and v8 differences in radiator sizes
From what I found online for the 2000 model year the radiator is the same size, but the hose connections and fill neck are on opposite sides for the I6 vs. V8. I was accidentally looking at 2001's first and they are different sizes. I would double check everything before tearing into it. My information came from rockauto.com. Most of their descriptions for radiators include measurements.
