It sounds like your fan already deleted itself, and took the bottom of your radiator with it. This is unfortunately all to common with these older cars. The old fans get brittle, and break off at high rpm's. A new one will probably take another 10 years to break. You will sadly need a new radiator from the sounds of it, and a new fan. You can use this opportunity to do the clutch fan delete mod if you like, either way you need to get a fan in there.
