Red face Would a coolant filter help?

Had a new EGR valve & cooler installed last week of June (expensive!) Kept hearing the fan kick in high gear. Took to another shop (back where I bought the truck), 2nd week of July. This time I paid for a new oil cooler, and yes, another EGR cooler. I did get the old parts, and yes you can clearly see the sludge in the coolant portion of the oil cooler. Oh yeah, the truck is stock and has 114k miles on it.

Technician tells me that Ford has redesigned the oil cooler to reduce oil cooler problems. True or not? I don't know. Just looking at the cooler and how it integrates into the engine, I don't see what will prevent the sludge from collecting again. Nor do I see how flushing the coolant system will remove any coolant sediment that's settled in such a recess.

I've been reading that some are installing a coolant filter off of one of the heater hoses. What do you think? Will it work? Better than nothing?

At this point I've decided that the 100k coolant flush isn't nearly frequent enough.

It sure wouldn't hurt. If the 6L block is like the 7.3L block...the benefits of removing the casting sand from the block are enough to warrant getting a coolant filter.

It can't hurt anything, go for it. It's on my "to do" list.

I say it mite be something worth looking in to. I talked with Loki Wolf last weekend, hes got a coolant filter on his truck. The install was pretty clean and looked fairly easy too. Just "T" into the heater hose, "T" into the overflow hose, and the filter housing mounts to the radiator support.
Im sure he'll be along with some more comments.
After he said something bout the first filter change having a pile of sand in it, Im considering doin the filter myself. As soon as I can get caught up with my other mods I need to install.

I believe the first one should be changed after a few thousand miles, the second a little longer, etc, until you get the initial "gunk" out of the engine. Then just make it a regular change. You'll be able to feel the return hose while the engine is running, if it's cold then the filter's clogged and needs changing. Here's one such system with some pics of what you'll get out.

Installed a Dieselsite coolant filter at 10,000 miles, 35K now. Changed the first filter at 1,000 miles, tore it open and it had about a tablespoon full of sand and some sludge that was like toothpaste. Changed the 2nd filter after 3,000 miles and got about a teaspoonful of sand and more sludge. I've changed it twice since then but didn't tear them open. The Degas bottle doesn't have the 'coating' crud inside anymore either.

After seeing the sand and sludge it filtered out of the cooling system I definitely recommend the coolant filter.

Thanks for all of the feedback! Apologies for the sabatical...issues. I'll be ordering that filter system and doing an install before I run over to Talladega for the October race!
