The VC-9 is an iron/scale remover often referred to as an industrial class boiler cleaner. I know when I flushed mine the internal metal that I could see looked virgin in appearance. Almost like it had been bead blasted.

New oil cooler at beggining stages of plugging.did the restore flush before changing it to a tee,then ran gallons upon gallons through the system.now I'm getting scale flakes out of my radiator constantly.its gotten better,but unless its perfect ill keep going.got the vc9, that'll be my next step.the scale looks like calcium deposits.bought the truck used so I'm thinking I inherited lack of maintainance.thought about old schooling it and running cascade in it before the vc9.it never ends...

Simple Green won't touch rust/scale. If you want to clean your coolant system really well, it takes more than one step. First you want to remove any sludge in the system with an alkaline cleaner like Fleetguard Restore. After that is flushed out with water, then you want to use an acidic cleaner like Restore Plus or Motorcraft VC-9 to remove any rust and scale and to prep the metal surface for the new coolant to bond to it. After several flushes with distilled water, until clean, add your coolant. I recommend Fleetguard, CAT or another brand ELC coolant rather than Ford Gold. Add 3.5 gallons concentrate, then top off with distilled water to get the correct concentration.

It takes a lot of flushing, took me the better part of a day to flush my dad's '03. If you are just using the radiator drain, it will take a lot longer. I pulled the driver's side block plug and that got a lot more out each time.

I thought the vc-9 was just for rust but if its for scale to Id dump at least 2 quarts in make it strong run it then let it soak for awhile then run it again before you flush the vc-9 out give it plenty of time to break the scale down
Then stuff a hose in and try reverse flush where the thermistate goes with drain plugs out radiator and driver block might even consider pulling the passenger block drain plug out since it sounds like its full of junk
pull the lower radiator hose to junk always seamed to get traped there

when I did mine I ttook out the thermistate and set it to high idel in drivway for an hour with the cleaner in it
plus the high flow with the thermistate out may help break up the scale
It gets hotter just sitting there at high ideel if you take the thermistate out
I dont know how hot it needs to get to make the vc-9 work I heard the restore had to get to operating temp 190 wonder if the vc-9 is the same
on the 2011 whats urea injected
