My daughter did the same thing to our 91 300E a couple of weeks ago. I took the fan off and the engine starts.

Those cars are only worth $3 - 5K so it is tough to justify to repair them. In my case, I need a hood, left fender, radiator, grill, an clutch, fan, headlight assemblies, radiator support, etc. Unless someone can find another one as a donor for parts, it would cost too much.
