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? :confused:
 
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

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.
