Check you cooling stack!
So I felt my 2006 LBZ was getting a little more warm then it should while towing my trailer. Nothing big. It would get up to 225 in 90 degree weather and the fan would come on and take the temp right ...

I have the same LBZ and have overheating problems too.
I suspected a plugged rad, so I had it removed and at that time had the crud blown / hosed out of the rest of the stuff in front of the rad. A multitude of bugs and other debris came out.
I didn't have the bucks for a new rad, so I put in a known good used one for now.
Everything is clean in there but my LBZ still gets dangerously hot hauling my TT up a long grade.
My next fix is a brand new rad to see if that helps. Can't believe the money they charge for stuff like this.
That's why it's important to check the cooling stack. IOW's the radiator is the last in the stack. It may be spotless but if the intercooler is plugged up with sand (like mine was) the radiator can't get cool air to it to do its job.
The whole cooling stack needs to be inspected, not just the radiator. And I do mean inspected it. A lot of people just glance at it and say, ya, looks good. You really should shine a light through the front side row after row to give it a good inspection.
