Restore/restore + in a 7.3??

I am looking to change the coolant in my 7.3. It currently has the Ford Gold coolant in it. I ordered the zerex ELC from NAPA and will be in tomorrow. Plan on a new thermostat, upper and lower rad hose, thermostat housing from dieselsite. The 6.0 guys all use the restore and restore + to remove the silicates left behind from the gold coolant. Should I use the chemicals in the 7.3??

I didn't use any in mine. I flushed it out really good with the water hose though. I would assume for the amount of water you're pushing through the system that it would get most of it out. Then you're going to add several gallons more back into the system which I would think would dilute any silicates?

I don't think you have to be as through because the Gold isn't as incapable as the Green about getting every bit out before you go with an ELC...

I wouldn't use Restore, if you're really concerned you can do this kind of flush -> Gooch's Radiator/Engine Backflush Procedure and Coolant Information - Ford Truck Enthusiasts Forums
