I have a loose radiator fan, what will I need to fix it?

The car is a 1988 Mercury Cougar V-6. I don't think its an electric fan, but anyway its very loose. I think i'll need to take the radiator out first, because I can't get the fan shroud off, the fan won't allow it. So I'll need to drain the fluid etc. I was just wondering if there was a temporary fix to tighten the fan. This car is my only transportation and I need to get to the nearest parts store. I would walk but I live no where near anything, so I can't. Please help!!!
