Ian,
I didnot have any overheating issues with my 05 dually, same with Larry. Maybe neither of us is a lead foot? or trying to pull at unreasonable speeds etc.
If you want to talk about overheaters, try the 6.5td from 95-97 with the auto trans. I had some issues with my NV4500, but not near the temps issues as those with the auto trans. I solved most of that issue with the post 97 cooling mods.
Of course this is not to say some or all of these did not have issues.....with the HP/torque a lot of the new motors are producing, an excellent cooling system is a must.

Most did not have overheating issues. Those that did were easily repaired with some LBZ components (of which I cant remember exactly anymore what that was). Grandstand on the issue if you like, but it wasn't wide spread nor was it a big deal to correct.
What percentage had over heating issues is anyone's guess. I'd categorize it as a significant problem that gave GM's diesels a bit of a black eye, much like the injector issues the LB7 had.
Google it for yourself. I realize it's 13-14 years ago now, but a
2 second google search will show there's still plenty of plain to see info still out there about it if anyone cares to look. If not, that's OK too.
