I had an 01 Xterra for a bit...luved it. I don't care for the newer big pigs; they're just overgrown luxury wagons where-as the older X's were far more practical and a properly modified Xterra can be a ba-dass off roader. I made the mistake of trading the X for a VW Jetta. ..anyway, yes, change that radiator if it looks original, and check the timing belt also. The rear wiper motor should be easy to replace.
