it's not over heating but would prefer it not to go over 210 ever .mine is a 03 with 76000 miles and I'm pretty sure the bottom 3 or 4 rows are cloged up ,after 5 years . Texas can get pretty hot but Arizona in the summer is realy hot . that reminds me of a joke ,A texan,a Newyorker,and an Oky are takeing a leak off a small bridge over a stream. the Newyorker says damn that water is cold,the Oky says yep and the current is moveing pretty fast about a foot down ,and the Texan says shure the hell is and the bottom is muddy as hell too.
