Coolant Filter Pics... What is this?

[05P0werStroke]

When I flushed out my truck I found alot of metal particles in the bottom of the drain bucket. Now after running for a few months the same particles are in the coolant filter. It looks like the block is rusting and flaking off but how could that be when it has had coolant in it the whole time? Any help? thanks

It looks like a mixture of casting sand, and gunk from inside your engine.

Also, make sure you aren't using a coolant filter with a Supplement Coolant Additive (SCA) as said filters are designed for much larger trucks and the additive can contribute to the development of this sort of sludge when used on the smaller 6.0L.

I don't know what the rest of the guys will say but I'd want to flush my engine again if I was pulling out that much crap on an engine post-flush/ELC coolant install.

Nasty hope mine doesn't look like that ,at least the filter is helping , I firgue even with the filter for me it will be about every 6 or so years a oil cooler rebuild.
Could be radiator little rust, can't really say for sure

Do you have any insight on the history of the maintenance of the cooling system? Did you buy the truck new? If not, do you know how diligent the previous owners were with regard to checking their coolant/getting it flushed? You could just have a neglected cooling system that's going to take a long time to get clean.

Well, that's a plus then.

What's the coolant in your degas bottle look like? Nice and clean?

Did you do the whole 8-12 hr flush advocated here on the Org? Restore/Restore+ and the whole shabang? Or just a basic flush?

I filled and flushed about 6 times with distilled water, used like 50 gallons of water while pulling the driver block plug and lower radiator hose, I used the vc9 in one of the flushes and the degas bottle looks good and clean

Judging by the pictures, and the explanation of the flush, it looks like you didn't get everything out of the block. VC9 is for rust removal. Restore is for removing the silicate crap left over from the Ford Gold coolant.

I'd flush it again if it were my truck.

There's a ton of threads on this subject here on the Org. Do a search. Also, this is a pretty nice writeup: http://bit.ly/rE6Ghx
