Change to ELC - Check!

This weekend I got around to flushing out the gold and putting in the new Zerex ELC. Process wise:
1) Dumped out the old, removed the thermostat, removed the coolant filter and bypassed it, and flushed out well with tap until clear (after removing the lower hose and rear engine plug)
2) Flushed with Restore Plus and again, flushed that out with tap water till clear
3) Flushed with Restore and again, flushed that out with tap water till clear
4) Flushed out the system 6 times with distilled water (went thru 25 gallons)
5) Installed new Ford thermostat
6) Filled with 4 gallons of Zerex ELC EC-1
7) Topped off with distilled water

It was a much longer process than I was expecting. Luckily, it went well. The plug in the block actually came out easily!

Did some driving yesterday afternoon and Edge told me by deltas between ECT and EOT were around 8 degrees. I'm happy....and I hope my truck is happy! Since it has a new OEM EGR and Oil cooler on it, I suspect it should last many, many, many years worry free.

Now...onto getting my Firestone Air shocks installed!

Two things I noticed:
1st, I hope you just wrote #2 & #3 backwords. Restore should have been used before Restore Plus.
2nd, You should have only used 3-1/2 gallons of ELC. I do not know if having the ratio off will affect anything. Hopefully someon else can say.

I asked previously to this....and:
1) It seemed as though there was no right or wrong way of which goes first and which second (Restore and then + or + and then Restore)
2) In previous thread from Mitch, he noted 3.5 to 4 gallons ELC. 4 Gallons would put the mix at 57/43 percent....so I don't think (or hope) it's that big

Here is the link I referenced that talks about the sequence and the amount of ELC. Restore radiator flush question

A higher concentration of the ELC will just lower the freezing temp of the mix. A 50/50 mix gives -37Deg C protection and 60/40 mix gives -52 Deg C with the chevron ELC.

Maybe the mix wont be bad. Normally you buy 4 gallons, use 3-1/2, then mix the extra 1/2 with distilled water to use as make-up when needed.

I believe the order of Restore use is important because the Restore Plus (or VC-9) remove heavy metal deposits, but do not affect the silicate/gel/crud that is covering everything. You flush with Restore first to remove that crap, then VC-9 or Restore Plus cleans out any heavy metal deposits or scale if present.

You can go up to a 60/40 mix and it will just raise the boiling point and lower the freeze point a bit more. 50/50 is adequate for most of us but anything up to a 60/40 mix isn't going to do any harm.

The order of Restore/Restore Plus is not really important. Getting all the soap residue from the Restore out can take a while and if you get most of it and then do the Restore Plus it seems to help get rid of the rest of the suds from the Restore. Anyway it is nothing that a few more flushes won't cure.

My flush procedure is not meant to be the definitive flush procedure. It is just one way to get it done for the folks that aren't sure what to do. The bottom line is as long as you get the old stuff out, flush it good with Restore and Restore Plus, then get it filled with ELC and distilled water any way that works for you is as good as any other. The major point is to get it done.

I got some questions if anyone can help me out with them.

I went and picked up some of the CAT ELC, its the 50/50 mix, will I be fine running it instead of the concentrate? Or should I go back, return it and order the concentrate?

Also, the local tractor store only had Restore Plus, and no Restore. Am I fine with just flushing with Restore Plus? Or should I wait until I can find a bottle of Restore?

Thanks

Due to not being able to get all of the water out of the system after the final flush, you want to start with concentrate, not 50/50. How much water is left in there is not known, but it's a 7 gallon system, so filling with 3-1/2 gallons of concentrate and then topping off with distilled water is what you want to do.
