mildly concentrated sodium hydroxide solutions would corrode the living fuck out of aluminum pretty quickly (https://www.calpaclab.com/aluminum-chemical-compatibility-chart/), especially when hot and circulating, so no

could have been a kind of additive maybe? but then it won't be a lot of it. borax forms a gel or at least high viscosity solution when mixed with glycols so both can't be used at the same time as a coolant

Dye might be fluorescein, it fluoresces under UV (duh) could be useful in checking what's this thing

i have no idea what they were cooking but it's not coolant, unless temperature there never drops below 0C

I think @ChicoSuave above figured it out. It was used to flush the coolant.
