Coolant flush and oil cooler?

My wife wants to do the flush and elc swap in her '10.

Do the oil coolers in these trucks have the same troubles the 6.0's have? Haven't heard much of anything so that is a good sign in my book, but still.

Right now it runs roughly 192 ect and 195 eot, sound about right? Only 27k on the clock and has the egr system removed.

I am assuming the restore and restore plus are used for this application as well, and a coolant filter. Plus, a ton of distilled water.

Just wondered if some of the same pitfalls are at risk as with the 6.0?

a tech on here said do mot flush the oil cooler, just drain out all coolant... a flush could loosen any sludge and clog the oil cooler...

That happens with the 6.0 as well. At 27k, surely there cannot be that much buildup. We want to get it out before it becomes a problem, if it ever does. And changing coolant every 50k is just plain stupid, whoever come up with gold should not have a job.

My 6.0 had 45k before I flushed it and I mainly got sand out. I had a new cooler put with the studs, but the old one didn't have much buildup at all.

i did a VC9 flush and refilled with CAT ELC. My delta stayed between 4 and 5 degrees. This is what the flush looked like...

I have an 09 with 61k miles on the clock and have not yet done a coolant change to my knowledge (but i bought the truck at 57k miles). I want to do something very soon. Should I not do a full flush at the dealership due to clogging the oil filter? What should I do? I could just empty everything myself, but i thought that If i didnt use the coolant flush "machine" to suck everything out without introducing air to the system, them serious problems could arise? Any input would greatly be appreciated

my personal opinion is to do a chemical flush before refilling. If so much stuff is broke loose that it clogs your oil cooler then it needs a flush anyway. If it has that much junk it will eventually break loose and clog the cooler anyway. I also highly recommend a coolant filter.
