Flushing cooling System
Who at this dealer told you that?
Pretty obvious to me your dealer staff doesn't read the tsbs or the special service letters.
Read this similar thread from last winter.

I'll be replacing my coolant soon as well. Takeda, please let us know how much coolant you get out of the radiator. Will you be using Motorcraft antifreeze or aftermarket to refill?

Any particular reason you went with that vs Motorcraft? Is it pretty much the same as the new Motorcraft antifreeze? I'd like to use an aftermarket antifreeze, but still need to research what exactly meets Ford's latest spec.
My truck has around 38k miles on it; low for a 2016. First coolant flush is scheduled for 100k miles, I believe. This truck was going to have Dex Cool in it for the next four to five years anyway. I knew about the change to the yellow stuff, but I just didn’t care enough to go out and find the new coolant.
Just curios, I assume that there aren't drain plugs on each of the sides of the block just below the freeze plugs anymore----bummer

I did the flush today! I started by running it to normal operating temp, with the climate control on HI. I did this so the thermostat would be open when draining (thermostat housing goes to the lower radiator hose). I let it drain until it cooled off, then removed the thermostat, putting the old O-ring back in. I've never seen anything mentioned on the orientation of the bleed valve in the thermostat, so I noticed the orientation of the old thermostat bleed valve. It was at 3 o'clock. After flushing with 12 gallons of distilled water, I installed the new thermostat, and O-ring. It initially held 1 gallon of coolant, but after running, getting hot, and bleeding air from the reservoir, I was able to get another 1/2 gallon in. I think after letting it cool down all the way tonight, I might be able to get another quart in. While draining, and refilling with distilled water, it's difficult to refill the system.
A vacuum purge kit is usually required to refill the coolant properly. A must when I installed a supercharger on my mustang. Done in minutes with no air in system. Doesn’t Ford recommend this for the F-150?
