Yea that is good stuff also the Shell Ultra has very good reviews so I would go with one of those two myself.
When you do the flush don't use acid. I have read countless posts of horror stories about it knocking everything loose in the block cooling system mostly my sand and some cast iron only to plug the oil cooler. Talked with a guy last week who used the Fleetgaurd cooling system cleaner which is like VC-9 Restore and his oil cooler is toast.
Anyways this is what I did to my truck and a friends when we switched the Gold out for the ELC.
Remove thermostat and completely drain the cooling system pull the block plugs too. A ball socket Allen wrench will fit into the passenger side plug do you don't have to pull the starter. Anyways drain it and run water trough the hoses to get as much Ford Gold out as you can. Then fill with water and 2/3 cup of liquid Cascade dishwasher soap.
Take the truck for a 30 minute drive to heat it up as much as you can. I got up to around 180 degrees and that was as high as it would go without the thermostat.
Pull all the hoses and block plugs including the heater core hoses along with all the hoses to the coolant tank. Run water in both directions to everything all hoses and into the thermostat housing etc. refill and run truck 10-15 at idle then dump it again and flush everything again same way. This time refill with distilled water and run 10-15 minutes at idle. Drain everything again block plugs too of coarse. Refill one last time run for another 10-15 minutes drain again for the last time.
Pour in 3-1/2 gallons of your EC-1 of choice and top off with distilled water.
The Cascade will break down the silicates from the Ford Gold plus it will clean the engine and radiator etc without etching the iron or hurt the rubber plastic in the system.
I forgot to mention reinstalling the thermostat get a new Motorcraft one ONLY they are $30.00 at the dealer. I did my buddies truck and mine almost 2 years ago now and both of our Delta Temps are 3-4 degrees still today.
One thing I did notice with my truck is how much better the heater works. I can light feet on fire now and couldn't do that before. So yea it cleaned out my system for sure.
There are plenty of diesel shops that do it this exact way and I am glad I listened to a mechanic when I was ready to do the switch in my truck because it works and works without over cleaning and creating a problem.
My Cat EC1 is clear as glass today but being I am coming up on 2 years I will change it out soon with some new stuff for safety sake.
It is the Red Coolant. Looks like Kool Aid to me and it is quite thick. My friend bought something from ORiellys and it was really thin like water. Not sure of the difference but I went with Cat because that is what International runs.
Good Luck on the flush.
