Havent checked in for a while. I have some updates on this cooling issue. I kept driving it, without doing any work on the truck. I noticed the engine getting louder, was worried the engine was going to blow up at some point. It got to where I checking the oil daily, but it never really needed any. Then one day it got really bad, I thought I wouldnt make it back- really loud! Every time I opened the hood-everything looked ok, oil,coolant,etc. Then I spun the cooling fan.. it spun easy and I could hear the bearings.
I got home, installed new fan clutch. Engine is super quiet! and no more hot issues in traffic. I know fan clutches go bad, but the way this one sounded like an internal engine rattle was a new one for me. Anyway, I just wanted to share that in case it helps someone.
