Since there are many members at the .org and many other forums that are on the fence of elc change,want to take a poll of people that has done the total flush and change with zero problems.

Hopefully there will be members that have done this and will have years of experience their coolant.

Like i said, i am retired,fixed income and do not have the luxury to experiment.
Please do not tell me that i have the wrong truck for retirement.

My deltas are 5-7* @ 84 * ambient temp,<46000. miles and no severe signs,form the degas bottle other than just being cloudy.

Let the opinions begin:crazy:

I did the full flush and switch. About 8000 miles ago. Not only zero problems, but a cleaner system (looks like I put a new degas bottle on)

EDIT: On a side note, my system was healty from the get go. Never above 7* delta, with AC on highway 75mph.

No help here. My system was so clean that we didn't bother flushing it. At the time we didn't know what the coolant in it was but now believe it was the Ultra ELC. It was yellow, not gold! If I had know I would have probably left it in. Looks like the original owner of mine took pretty good care of it. I will say after a couple thousand miles on the cherry koolaid, my system is still very clean and I have no delta issues. If I'm running 85-90 for an extended period of time on a 100 degree day, I can get deltas of 13-14 degrees. But almost immediately after slowing down the delta drops to about 5 degrees.

thanks guys for your input. I am really leaning to a water flush then Final Charge by Peak to be used.

Hopefully this thread will clear the air of to do or not to do

If you flush everything and reverse flush everything I can't see how you'd ever end up worse. Just be sure that you flush everything and reverse flush everything including the heater, radiator and especially the oil cooler.

The point is to prepare a clean system for the ELC. Cleaned and thoroughly flushed it shouldn't be a problem unless your oil cooler was on the way south to begin with. I had no problem with mine.

Did the flush, zero problems, went with Fleetrite ELC which is what International uses.

I switched, haven't had any problems. Did the flush word for word and went with Shell Ultra ELC. Delta's weren't ever a problem 5-7* and are nearly identical afterwards. I did however run a few coolant filters afterwards just for piece of mind thinking if there was anything suspended i'd clean it up quick. Glad i swithced and loving the shell ultra!!:icon_ford:

Same story here. I used the Restore only and refilled with the Cherry Koolaid as well. My delta is 4 deg on a normal day , but never gets pas 11 deg when working the old girl hard.

I had 60k miles when I did my flush, I did the restore and restore +, flush, flush, flush, etc. Truck was pretty well taken care of before I got it, my deltas are good, the most I have seen on a hot day pulling heavy are 14, and that was once. My avg deltas are 5 ish.
