Thanks for the oil cooler location brian. I really appreciate that. I'm about to get underneath this truck and start pulling plugs and loosening drain plugs...
I just want to confirm though that with the rotella ELC, I do not have to add any additives?. I have a concentrated mix, I have 4 gallons, and then I will add 4 gallons of distilled. But that's all I have to put in there, correct? Should be done here in the next few hours.

As MARCSPSD said there will be water trapped in the system. There will be a lot less residual if you drain the block too but there will still be some in there none-the-less. That's why I do multiple flushes with distilled water (fill, run, drain) to make sure that what's left in the passages is as close to fresh distilled water as I can reasonably get it.
Since the system is 32.75 qts (8.2 gal) that makes it convenient math: 4 gal of ELC concentrate + 4 gal of distilled water = full coolant system (effectively). After adding the 4 gallons of ELC concentrate, the 4(.2) gallons of distilled water ends up being the difference between what's still in the system + whatever it takes to fill the system and top off while working the bubbles out. I always made sure to have extra jugs on hand (not a wallet-breaker at $1+/gallon for distilled water).
There's plenty of nooks and crannies for water to hide (and not get drained) so never got close to adding 4 gallons of distilled on the final fill (even with topping off for the few days following while the bubbles got worked out of the system).

I did notice that my coolant level is slightly lower than it was a year ago. I bought this truck in 2018 and I haven't touched the coolant. It look like it was in good shape, so I left it alone. Perhaps I have that cooler leak like you mentioned. If I do it's not too bad yet.
