Today while driving to the gas station I noticed my battery light on. When I pulled up to the pump and turned the car off I heard a loud thud noise. So I popped the hood and the noise happened to be my alternator belt pulley falling off and hanging there by the belt.

Luckily the bolt and locking washer were still there. I got the pulley back on and bolt tightened down. So my question is is there anymore hardware other then just the bolt and washer that I might have not seen laying on the ground? I'm extremely skeptical about driving my car now.

Oh and I have a b16a engine if that helps.

 

All your hardware is there. Aside from the pulley bolt there are there are two bolts (top and bottom) that hold the alternator in place. Bottom bolt which the alternator pivots off of and the top bolt to tension the belt.

Re-tighten everything back to spec and you should be good.
