Strange rattling - could be the fan

[John Gottstein <gottstein@erols.com>]

Is the plastic cooling fan supposed to have a little bit of wobble, or should 
it be
really tight?  My fan is attached tightly to the fan clutch, but the whole 
assembly
seems to wobble two or three milimeters when I give the fan a push.

I couldn't get my hand in far enough to see if the fan clutch can be tightened. 
 Can it
be, and does anyone think that this could merely  be the source of my strange 
rattling
sound.  I've now ruled out the alternator?

Thanks a lot,
     John
