Thermocure is fertilizer and salt.
The Diammonium Phosphate is why the coolant is coming out black
Here is the MSDS

So no any other additives, just proper flush, drain (including engine block drain), and fill Mopar 5 year?
Yes but we never drain the block.
I have drained the block like 5 times during my flushes. Is there any problem with doing it?
I work on the cooling systems with a serious eye towards solving the problem and getting done with the job in the least amount of time possible. So, we pull the thermostat and do several flushes with hose water until it runs clear. Then we flush with distilled to dilute the tap water to a tolerable level. After that, we mix the coolant 2/3 to 1/3 distilled which when mixed with the water remaining in the block brings the dilution rate to 50/50. After the drive around flush and Thermocure if needed, takes us about an hour start to finish. That runs into most of a day if you dick with draining the block and waiting on the thermostat to open every time you flush it again.
Yes but we never drain the block.
Was wondering g if pulling the lower hose would drain it all without pulling the block plug?
Don't know or care. It isn't lower than the drain valve in the radiator.

Pulled my drain plug and nothing happened at first. Odd.
Then I see something is blocking the flow, so I push whatever it is in with my 8mm socket.
After the flow stops, I stick a magnetic extender in the hole and I get gobs of ferrous material.
Any idea where this metal could come from?
Is it the water jackets rusting away?

Update on my progress:
Ran exhaust gas in coolant, no issues.
What does this mean?run exhaust in coolant

Probably just many years of rust built up and it finally broke loose. This was from the engine block drain?
Looks like a good time to do a thorough Thermocure flush.
Test he means he performed the test I assume lol, looking for a bad head gasket
