I installed my system about 2 months ago. Looked in the degas bottle the other day while the motor was hot and still running and noticed that the coolant was only dripping into the bottle. Guess the filter filled up quickly, under 2 months of use and not even 1500 miles? So i changed it today. How much coolant should you be able to see flowing into the bottle with a clean filter?
Mine is a small but steady stream. The easiest way to tell when the filter is plugged is that the return hose will be cold in relation to the other hoses including the radiator hoses. When my first filter plugged up, the filter housing was actually cold from no flow.
??? The return line from the filter 'T's into the return from the radiator. You'll see coolant return into the degas bottle even if the filter is plugged. The best way to know if the filter is plugged is if the return line from the filter is not hot.
I'll probably wait til the line is 'cold' because when the filter plugs, it just doesn't filter anymore. Coolant flow is not affected at all.
Thanks for the replies...once all the air was out of the filter and the entire case was hot, it flowed good. Much better than the drips i saw before the change. And i haven't pried open the old filter yet but when i turned it upside down in a bucket i could see a lot of sediment lying in the bottom. Another good investment thanks the guys on this site..

I pour the fluid from the filter into a coffee filter and check what was "loose" and the fluid that I poured out... I just our back in the degas bottle as the coffee filter caught all the bad stuff.
My gallery has photos of a cut open filter and I am sure yours looks the same if it clogged up that fast!!!
For the money.. this should be everyone's first mod!!!

I just went thru your gallery, nice job. there are some great pics.
Can anyone tell me where all the debris is coming from in these coolant filters? you would think that is would be all gone by the 3rd filter change?

Sandcasting. The molds they use to make the blocks. The sand will continue to works it's way out of the block over the life of the engine. I assume it also takes awhile for all the sediment that has collected over time to make it's way through the coolant filter since it's a bypass system and only filters a portion of it why the rest of the coolant passes through.

Thanks.... took awhile, but pictures are worth a 1,000 words when trying to explain or justify what I have learned over the years of owning a 6.0L truck.
The block is casted in sand and the sand is not 100% cleaned out prior to assembly. Over time, it works loose and just floats around. The trouble with flush and refills is that the sand and other "crud" settle to the low points in the cooling system and never flush out. When the motor is running and the system is pressurized, these particles, sand and crud move through the system and it takes several coolant filter changes to catch most or all of it... and over time... sand still works loose.
Heck, I have 99,000 miles on my 2003 6.0L Excursion and I stll get "stuff" out of the filter when I change mine!!!
i just replaced my filter last weekend and poured the coolant from the filter through a coffee filter.
i did not see any sand, but i did see some small metal pieces.
not real sure what could be causing these in the coolant system.
Seems the water pump is the only metal thing moving in the coolant system.
leftovers from the block's machining process?
how does international clean the block, after machining it?
solvent immersion? would that flush all the machining by-product from the nooks and crannies of the block? are there any shavings floating in the solvent immersion?

Who knows... but at least the filter is catching it. These motors are mass-produced... so anything is possible.

you have to cut the filter open to see what is trapped in the element...
