This is after 1500kms of driving with my 2nd coolant filter with the sinister coolant filter system!!is this actual sand?where is it coming from?I flushed with distilled water and restore and restore plus....and added delo cat ec1 elc coolant!!Just no idea where this stuff is coming from!

[smokejoke]

What kind of filter are you using? What's the brand and part number? Make sure that your not using a charged coolant filter!!!

[Tommyboy7777]

Its a fram,non charged forsure!!

[Tommyboy7777]

Oh,part# PR3383!Its the proper filter,just curious as to what that stuff is its catching!

Yes, it's casting sand and a little silicate goo from the old ford gold. Now your glad you have a filter, right.

Seeing those pics only scares me enough to want to get a coolant filtration system for my ride ASAP!!! Tommy, just be glad that THAT is material that is being filtered out of your cooling system. I find that it doesn't matter how well, or how hard you try to flush your cooling system out, you will never be able to clean everything 100%. This is why it's not uncommon to need to replace two or three of those filters out within a short period of time, after an engine has "been into" if I'm reading everything correctly.

Ya I guess its a good thing that its not runnin thru the system!Just surprised to see that sand!I've been changing the filter every 500-750kms!Hopefully a couple more changes and this stuff starts to disappear!
