I have spent the past week or so flushing my 6.0, doing the most thorough job I could. The restore only pulled out a tiny bit of goo and the restore plus didn't have much if anything in it, I was pleased with these results.

I followed this http://home.comcast.net/~lyon.family...ush%20v1-0.pdf

I also added a coolant filter and did the blue spring upgrade and new thermostat.

After my final chemical flush I have done about 7 distilled water flushes and I'm still not happy with the clarity of the water coming out. I feel like at this point it should be clearer. I have high idled it and driven it around on every flush getting it to operating temp. I have attached a couple pics....is this the clearest i can expect the water running through a cooling system? I will flush it another week if I need but the past 3 seem to be the exact same color. I have emptied both drain plugs every time and put in a full 5 gallons of water every time.

Does this seem normal? Most write ups say do 3 flushes or so after the chemicals and I've doubled that already. My system never was dirty especially compared to other pictures I've seen of people doing a flush. And my deltas were good previously and have been during and since. It had the ford gold originally.

Thanks for any help as usual!

These are samples from flushes 4-6 from left to right and water on the far right.

 

I don't think what you've done is unreasonable. Are you using the block drains or just emptying the radiator? It'll take more if you don't do both.

Mine took six flushes (draining the block and radiator) just to go from coolant to water, no chemicals:

 

Thank you for the pic and reply texastech. Id say mine are about the color of yours about 4 from the right.

I don't expect them to be perfect I guess but there still is just a touch more color than I thought I would have at that stage. I just flushed again and I'm debating filling it with the new ELC after this one after it cools.

Do you think I'm OK in my thinking?

 

Oh and I have been emptying both drain plugs every time (installed the fumoto valves) and also pulled the lower rad hose everytime.

The inside of the hoses are nice and clean from what I can see and were from the beginning (saw pics of nasty ones) and the degas bottle is clean.

 

Ok just took a sample of the latest (10th 0r 11th now) It looks exactly the same as the previous in my picutre. I can't smell anything in it.

I have to go buy water for the final fill so I think I'm gonna get enough for one final flush and put antifreeze.

I just don't want to take any chances of old stuff in there.

 

I just did mine a few weeks ago. 5 flushes with distilled water. I drained the block, pet **** and lower radiator hose each time. Drove it no less than 20 miles between each flush. Took me 2 whole days to finish.




The one on the left is actually the second drain. I had already disposed of the first before taking the picture. I didn't use any chemicals. Just distilled water each time.
I just took a pic of one gallon from each flush. Each flush yielded a tiny bit of sand (or what looked like sand). When finished, probably enough sand to make something the size of an aspirin. I went ahead and installed a coolant filter as well.

 

Hello TXmav thanks for the pic. With these 2 pics I'm confident mine's as clear as it should be. My pic does make it look a couple shades darker for sure, I took it in the shade in front of red bricks lol. But when i go out and look at the jug it looks like the 2 right ones in TXMAV's pic.

I haven't seen any sand and never had anything as dark as texastech's pic even after the chemical flushes.

It is sitting one last time right now, I'm gonna let it cool and drain and put in the antifreeze!

 

I think you're A-Ok. Last VC-9 flush I did the water came out black the first three flushes, and I don't even remember how much well water we ran through it before doing three distilled flushes for the ELC.

 

Ok great well the ELC is in, I chose Rotella because I have used their synthetic oil and have a good results.

Seems like a lot of TX guys here, Dallas rancher here....and that truck is my life blood lol.
