I’ve been working on a second round of flushing my cooling system for a few weeks now.
I started with Thermocure, ran it for 3 days and then flushed it out and ran Prestone flush for the days.
For the entire time I’ve owned this Jeep (13 months) whatever coolant or water I put in always comes out black after running the engine to get the air out. Right away black.
I have 18 gallons of water I’ve pored in and all of the water comes out some shad of black.
When I discovered I could use the the block drain plug, thick black goop was plugged up behind the plug.
What’s even odder is the black goop is actually made up of metal that I can collect with a magnet from any open hole in the cooling system. This stuff is everywhere and caused me to toss a perfectly good radiator last year due to it being clogged with this stuff.
What is it, and is there and end to this stuff?
Is my engine dissolving from the inside out?
Oil analysis says coolant in the oil, too.
I feel like maybe another 20 gallons will get it all out .
