Coolant filter change results
I just did my first coolant filter change after about 1000 highway miles after installing it with Fleetrite ELC and found nothing in it. Not a single grain of anything in the paper pleats. I replaced it with a Wix 24070 for $12 from my local parts store. It's hard to comprehend how there can be such a variation from truck to truck in the amount of particulates in the coolant.

Maybe because you have the Fleetrite ELC instead of the Ford Premium Gold brand. There has been discussion on the forums that some of the so called sand maybe actually silicate dropout from the PG brand, caused by extreme heat with the "EGR Cooler".

[quote=Troy Buenger;9315441]Interesting... A couple of questions:
1. Did you notice any sand particles when you drained the radiater?
2. Did you do the VC-9 treatment?[/quot
I didn't notice any sand because I didn't use a bucket and also I didn't use any VC-9. I flushed the system for about 5 hours using my high idle mod for about 5 minutes each time. I used hose water until the end when I flushed with 15 gallons of distilled water.

Sounds like you did a thorough flush and removed any loose/suspended particles. You may have to give it time before you notice any particles in your bypass filter.
I'm going to be doing a radiater flush/change in the near future and will probably opt not to do the VC-9 flush as you did.

Keep in mind that a coolant filter is a "by-pass filter", so with only having it installed for 1000 miles is not really 1,000 miles worth of coolant volume through the filter.... only about 10% flows through the filter... so you only have about 100 miles worth of volume through the filter.
You may have flushed it well, but sand and particles settle to the low points of the cooling system and do not flush out with normal draining and refilling. Only under pressure and filtration will the "particles" move through the system and then get trapped in the coolant filter.... but again... you have to wwait since you only filtering 10% of the capacity as your doing it.
I would let it go for at least 10,000 miles and see... and just keep an eye on the degas bottle for the "out-flow" to ensure you have coolant flow through the filter... if you do... the filter is still working and is not clogged.
Fortunatley, filters are not expensive and changing them is easy... so maybe just change it out in 10,000 - 15,000 miles and see.
God luck,

Good info, just changed my first filter after about 1500 miles, no sand at all. So I guess you could say it was an odd experience, happy my filter was clear but kinda wondered about it. I keep an eye on it, never had reduced flow, just changed it to see what was up. I have one more filter, and think I will keep an eye on it, looking at maybe a longer change interval...but watching degas flow regardless.

I will probably change mine once per year now or 10000 miles or in the unlikely event that it plugs. After 1000 miles the entire 27.5 quarts has been through the filter enough times that if anything was loose it would show up in there. I don't have to worry about the possibility of silicate dropout accumulating since I use elc now.
