Just drained the coolant and the normally green fluid has a brown tinge to it. Corrosion? Oil in the coolant? Is there a test kit for this?

It's probably just rust...
How old is is the radiator, when the was the last time the coolant was changed?
oil + coolant = chocolate milkshake

PO said she changed it 'recently'. The radiator core didn't look all scaled up.

Could be oil, rust, or she could have added something to stop a leak such as Bar's Leak, which will turn it darker in color.
