First off I'd leave the filter open and then change it when done. As far as the steps that Bill did, you really need to remove the t-stst when flushing this way. It will never completely open toodling around the block. I also would open the drivers side block plug when draining. You'll get app. a gallon there. If your not replacing the oil cooler delete steps 2 and 3.
1. Draincoolant
2. Add 2 cans of VC-9 and top off with distilled water.
3. Drive 20 to 30 miles, preferably at highway speeds.
4. Drain radiator at petcock first, then pull lower hose. Then remove blockplug on driver side. Not necesary to do passenger side.
5. Remove t-stat. To do this, remove air cleaner. Then 2 nuts on t-stathousing. Pry press. sensor bracket off of studs. Tight fit but it will move.Remove 2 more nuts and pull t-stat and housing from studs.
6. Remove t-stat and put housing back on. Re-assemble everything and fill withdistilled water.
7. Run at 1200 rpm's for 3 to 5 minutes and drain as described in step 4.
8. Repeat 4 to 5 times or until water coming at is as clear as water going in.
9. Install t-stat using new O ring. I used vaseline to hold the O ring inplace.
10. After everything is re-assembled fill with a 50/50 mix of Ford premium goldor Zerex GO-5.
11. Start engine and check for leaks. This is a lot easier and quicker than itsounds. If you don't remove t-stat then you have to run truck between eachflush till t-stat fully opens and then let cool down to work on it.
Highly recommend installing coolant filter kit while cooling system is empty. ffice

well i flushed it as in video, with what you said! i filled 3 5g pails up with spent coolant... it was NARLY!!
I flushed it because i didnt know when the other owner did it last... and im sorry to the rest of US... but it was getting warm today 85 90* and the delta at 65 on free ways over 20* around town 11-16... i was starting to suspect the oil cooler was starting to get clogged...
I did a a major flush like he did in the movie... let it idle with the hose in the truck for over 30 min... finished the flush... added the additive ford sold me... could be a waste of money but well see....
havent driven on free way but now the delta is with in 3-6* city so i have noticed a diffrence!
