Are you sure it's from coolant? Has the bike been in water? Are you low on coolant? I might suggest if you don't know the history of the machine, clean it up and try it out. Change the oil several times and ride it a little bit. Drain the oil and do it again to see if the oil cleans up. Keep an eye on your coolant level.
The previous owner may have gotten water into the oil, so don't panic yet.
