First time I heard about block heater flaking off and plugging cooler is this something new?

Yes, what a conundrum. It would be interesting to know what the high mileage no problem people are running although I'm sure you could put a "bell curve" to the whole class of high mileage trucks failure wise for repairs. I'm pretty amazed at how much crap I'm still getting out of my cooling system after all this time and miles, so the cooler failures don't surprise me.

The last time I tore my truck down that far, I looked into that metal tube and noticed a huge 1"x1" chunk of powder coating that was flaking off of the inside of that tube. I reached in with a pair of needle nose pliers and pulled it out.
Imagine how bad that could have clogged those coolers!

Sooooo, with all this talk about coolant, sounds like no one really knows what's in some coolants that could be bad or what I should look for in a coolant?
GO5 has silicates in it. Dexcool does not. But I read here not to use Dexcool. Huh?
From what I've read, after chemically flushing the system we should be able to use the OAT ELCs, sound right? CAT or Texaco ELC is what I am looking at. I also found Zerex ELC which is Dexcool compatible and silicate and phosphate free. Thoughts
I did find this thread which had some good info but still a debate.
