Thanks Glen.... I have been using Thermocure , a chelate product (same as evaporust) and that is what released the Green Snot. Additional information suggests that to best flush out the gel, do it with boiling water as it makes the crap suspends in the fluid.. then flush quickly.. if you wait, it may settle to the low spots.

Currently all flush is out the petcock.. Monday, I will be removing the upper hoses and flush directly down the heads. see what comes out. Then flush flush flush, and repeat with the Thermocure. .. run the engine... let it cool and flush more.

Trying to rig up an attachment to a hose (like a 1/4 plastic flex line) that will give me access directly to the block.. reverse flush there....

Totally forget.. do I have freeze plugs in my 59AB?

I have also found (suggested here in FordBarn) No Rosion and another alternative for crap removal .. and then after a complete cleaning.. addition of an inhibitor which I am researching, .. I am also in Maine, but store in warm garage.. so considering water only or 50/50 for the coolant.
