My Fan Came Off

Das right! My main fan (not the one for the a/c) came off the motor. Whoops. This is why the temp would rise at stoplights as I found out. So it’s just sittin there, causing a soft whirring noise of the spindle rubbing agenst the plastic.

I did a quick search, but I can’t find anything. What kind of bolt/nut or whatever would have to fly off for my fan to just come off like that? Whatever it is, I need to get a new one and screw my fan right back on there. Of course, I have no tools of my own (coz I’m a poor little bastard) so I’ll get my freind to help me. This obviously prevented me from LOOKING at my fan in close detail to see if anything was cracked/broken in there. =( So hoping it isn’t, you guys have any idea?
