Awesome Coolant Flush Procedure!
This is how I am going to do mine. I'm glad I found this vid. Because I WAS going to do powerstrokehelps procedure which is no where near as thorough. I love the way he finishes the flush with the block plugs out and revs the engine to blow all that gunk out
. I like this guys videos and have subscribed to his channel. Not that you guys are not a TON of help also. With that said what bit do I need for the block plugs. Is it a Torx?

. I just don't see how you can do a good flush without removing the tstat and block plugs. Yeah its a little involved for sure, but with a new to me truck I think this is a must. Or maybe at least the procedure one should do before installing a coolant filter maybe. Sorry for the repost of old news, I just like beating dead horses.

110% Agree with Josh Here
I didnt watch the Video BUT
Tried it Both way Thermo in and Thermo Out
Thermostat in was Just a Waist of Money on cleaners and such
Thermostst out with truck set to high idel (1100rpm) for an Hour Cleaned it Sweet
I also stuff Garden hose in at every spot I could and let it flush a few that way as well

Drained the coolant.
Remove the t-stat, reinstall t-stat housing.
Filled the degas full with garden hose and then dumped that.
Filled again and then let the truck idle until about 120 degrees or so.
Repeat.
I also had all the drains open and just let the garden hose run thru the system, also started engine and revved it a few times.
Then switched to distilled water and repeated the fill 'n' dump sequence.

Yes Sir^^^
I think I spent almost as much time Flushing as it took to change the Oil Cooler.
its one of those things that if you do it right the First time you May Never have to do it Again.
Unclejessie just keep in mind a Coolant flush may plug the Oil Cooler you wouldnt be the first Guy this happened to
When I did it I was Hoping the Oil Cooler would catch all the Trash as I was changing it at that time anyway

I'll add my FICM was rock steady 48.5-49 volts before the flush and after has been on a steady decline. Some 47.5's for a while after cold start, then some 46.5's, then 45's followed. The other week it flickered 44.5 volts a couple different times after a cold start.
Now, the FICM still held 48.5-49 all other times, but about 3 minutes after a cold start the voltage would creep down to 45 and then screep back up and stay.
Needless to say I should have a rebuilt unit from Ed tomorrow or Monday.
Soooo... use some caution possibly starting and stopping the engine during the flush. I may have been a little too ambitious draining and restarting.
