What I found in my coolant filter...

[rem1981]

Well, I decided to change my coolant filter the other day for the first time. I have around 3 months and 5,000 miles on this filter. I installed the filter the day I got my truck back from my head job. Along with new heads, I installed a new radiator, and all new hoses. I thought some of you may like to see what was inside (and is probably inside of yours as well). I know some people question the benefits of the coolant filter, but I am a believer. This crap should not be in your cooling system.

Looks like the filter is working! I have some questions...

Did you flush or not? Are you running ELC or is this with the Ford Gold?

[rem1981]

I didn't flush. I installed new heads and replaced the radiator and all of the hoses. Replaced the oil cooler. Running Motorcraft gold at the moment, but will be changing to ELC soon.

I did flush with water...not a VC9 flush, which I assume you were talking about.

Yep, that looks like casting sand. It's crazy how it could still be in your coolant, but it is and why we recommend the coolant filters... Glad yours is doing a good job.

Agree, looks like there's some silicate gel in there too. If you've seen the pics of the clogged oil cooler after it's dried some with all the silicate in it, looks just like that gel at the bottom of your filter cartridge.

Yeah, I didn't pay much attention to that last pic and now that you mention it, it does look like there might be some in there. Good catch.

I think there is more silicate drop out than casting sand. A good filter never hurts.

So wait a minute, you mean to tell me that it actually works, and its not a bunch of broo haha witch-craftery? Amazes me still that some still tend to believe these trucks are "perfect" right off the factory line and don't need "tweaks/mods/adjustments" or however you want to term it. I'm a firm believer, and looks like you are too. Great post.

I cut my first open, after 130k, and it was right after a coolant flush! Found maybe a little bit more sand that you did! If i would have known about it, I would have ordered one the day i got my truck. No 6.0 should ever run without one! cheap insurance
