What is the best way to bond a fin that has broken off a car fan?

My car has an inter cooler fan that is made out of very thick plastic, somehow when I was doing some maintenance it fell and a blade cracked off the fan. 

Is it safe to use superglue and baking soda to glue it back on?

      Best option,  but for those  with Euro cars, $$ parts,Devcon Plastic  epoxy works. use only a ;little bit, it Wont get off balance.Mine has held a year.. Many new cars held together w/adhesives instead  of spot welded.

    Replace the whole fan unit, bonding will put the fan out of balance! Plus it most likely will come off again any way!

    No. BECAUSE IT IS BALANCED  Equal weight of each fin make for less bearing wear.  Replace the fan with another.  Costly error on your part.  Maybe visit a junk yard and find a good one for very little money compared to buying a new one which is probably pricey as all get out.

    Mill-Spec epoxy should work DP-190

    Needs to cure to 100% before running the fan.

    Nah, replacement is the best option. Epoxy might work but it has to be balanced when running full tilt or it will wobble excessively. Something like that is a good junkyard item but check online with Car Parts.com to see if they have a cheap option. Some new parts might actually sell for LESS than old junkyard parts. Depends on the junkyard owner.

    Forget it. Even if glue DID hold, which isn't likely, there would be balance issues, causing the motor to fail.

      No. Devcon Plastic epoxy has worked over a  year.

    No. The blade will come apart again while spinning and likely put a hole in the inter cooler or radiator.

    Try that. It might work, but the balance will be off and it will vibrate. I would use acrylic cement.

      No. Use Devcon Plastic Epoxy. Does throw bal off a bit, yes, but it Works.
