Restore radiator flush question

Sorry if this has been beat up but I need your advice. My truck has 37700 miles on it and unfortunately, i recently did a radiator flush but used the ford coolant again. I also recently installed a dieselsite coolant filtration system. I have read a lot about going to an ELC coolant and i will be flushing out the ford stuff and going with a cat 1 ELC, but have a question regarding this.

1) considering I have low miles, would you consider using restore? My thinking is this: would there be that much silicate gel on my oil cooler/egr cooler to warrant this and if so, wouldn't this run a risk of clogging my oil/egr cooler with all the loose crap moving around?

I will be using the vc9 from ford as part of my flush but i am having second thoughts about the restore.

Thank you in advance for your advice.

If you are using Ford coolant, you must use RESTORE to clean it out. The EGR in our engines heats that coolant and silicates drop out of solution, eventually plugging your oil cooler and over heating the EGR cooler sending coolant into the engine. Especially if you have used this truck hard. Flush with RESTORE first, then VC9, distilled water, ELC. Do a search, I think 2 Stroker has a nice write up on flushing. I did mine, tons of silicate slime came out with the RESTORE.

I don't know if this is the write up John was thinking of, but it pretty much explains the process.

egr delete, cooler, and coolant flush questions

The only question I have to either 2 stroker or Mitch; Is is necessary to initially use distilled water to flush the system? Can water from the hose be fine for the first couple of flushes, let's say up until after the VC-9, then use distilled water:

There also seems to be some conflicting comments regarding the order of coolant cleaners to use. VC-9 then Restore or visa versa. It would seem to me you would use the Restore first then the VC-9 since the VC-9 has additives which prevent cavatation (sp?).

ELC is the coolant recommended and used by International for this engine. .
Coolant Flush for changing to ELC

Drain coolant by removing lower radiator hose. Drain block from plug on drivers side of the block. Remove the thermostat. Replace plug in block and put lower hose back on. Put thermostat housing back on without thermostat. Fill with distilled water. run for 5 minutes then drain as above..Fill and run 5 more minutes drain. Put in 3/4 to 1 gallon of Restore an top with distilled water. Drive it for an 60-90 minutes then drain. Flush 2 times with distilled water or whatever it takes to come clear. Put 2 qts of VC-9 or 3/4 to 1 gallon of Restore+ cost less and fill with distilled water. Drive it for about 60-90 minutes. Drain and flush after. Flush 3 more times with distilled water untill it come out clean. Replace thermostat or put in a new one. Put hose back, make sure block plug is tight. Add 3.5 gallons of ELC concentrate and top off with distilled water. Make sure to run engine for 5 minutes between flushes to circulate the water good. Have heater on set to hi while doing this to flush the heater core too. new t/stat from Ford it should all come together (housing-t/stat-o-ring) in a box. The part number is RT-1169

Yes i think it would work i think Mitch would say the same thing do the last flush in distilled water then go for it.

I think it would be ok to use, after the Restore+ cheaper than the VC-9 use distilled water the + or VC-9 removes the mineral so it should remove also the minerals in the water from the hose then go back with distilled water until clean the add the ELC coolant.

Yes it matters do the restore first this remove only the silicate slug slim then use the VC-9 this remove the mineral build up--- get the restore+ 1/2 the price of the VC-9
