Just wanted to let some of you know that I bailed on the thermostat rmeoval option. I ended up doing the regular 5 hour flush and dump for 5 times, and you guys werent kidding the last dump looked as clear as it did when it went in. Installed my Dieselsite coolant filter, got everything buttoned up and we are all good now. At least with attempting to remove the thermostat I removed the CAC tube and inlet mount tube and cleaned it up real good, Had a lot oil int he CAC tube so it looks like a CCV mod is in order, I will probably just buy the rifraff kit for 45.00 and call it a day on that one.
Check your coolant filter in 5,000 - 6,000 miles. Whether it is loaded with stuff or not, just know that your cooling system is running as well or better than it was designed by Int'l and Ford.

Here is Ford's brochure and recommendations for coolant in the 6.0: https://www.fleet.ford.com/truckbbas...LANTINFOSS.pdf
Note: They do mention using deionized (distilled) water in the brochure.

Yeah, I noticed when I put exactly 3.5 gallons and started the truck and then opened the ball valves on the coolant filter that the min level went down about another quart. So, I went about half and half with coolant and water, and then completed the min fill with a little more water today after allowing some air to escape.

Just an FYI...
To save money.. instead of buying the 1gal jugs of RODI (reverse osmosis/deinonized) water off the shelf you can go to Wal-Mart and use the refill water station..just bring your own container. I do this frequently because of my saltwater aquarium. It something like $0.30 a gallon.

The water that comes from the refill machines is just filtered and such... which is NOT distilled water (minerals removed).

I would follow the instructions to the letter. As with all caustic cleaners, time is an important variable.

You need to get your system up to temp and pressure and move the cleaner through the entire system. Have your heater on and on high to get 100% coolant flow through the heater core. By driving it, the thermostat will open and give you 100% coolant flow as well. The key is to clean it and do it right (this stuff isn't cheap). No reason to short-cut it.
Good luck,

Make sure your 30 minute drive is on the open road. No stop and go in town driving.

Thermostat Removal
First of all, let me say a huge thank you to guys like you who take the time to help others. You are truly a big part of what still makes this country great!
Secondly, I looked at my 05' F250 and the thermostat housing didn't look all that bad to remove, in fact I could do it with a bit of muscle power without moving or removing anything else. Now comes the hard part. I have the thermostat housing in my hands, and for the life of me I can't figure how to remove the thermostat short of a blowtorch or reciprocating saw.
Searching the web yields nothing except one post that seems to imply it cannot be removed from the housing.
So, now I sit here hoping one of you are online, or I go back to the 10 hour + way. (A way I REALLY DON'T WANT TO DO.)
Thanks again for all you have done and an early thanks for what I hope to be a duh moment in the next few minutes / hours....

Put housing in vice and push down and turn t-stat bar to remove. Reverse procedure for install. Use a new O ring. I used vaseline to hold it in place.

You have him covered Mark. The t-stat will turn either direction to come out.
