Cooling fan out of balance
 

2003 2.0l 5spd Fan motor connector came loose and hit plastic
cooling fan and broke a 4" piece out between two blades. Repaired
with some fine wire and epoxy but added enough weight I'm guessing
to distort balance of blade when running, causes some vibration.
Any suggestions how I can balance fan appreciated. Hate to spend
the bucks to replace motor and blade when runs great. Only 50K on
car. THANKS FOR ANY HELP!
