Have a 1989 V6 and yesterday the adjustment pulley, located underneath flew off. All that is left is the shaft for the pulley that rides on the adjusting bolt. The bolt is gone and I don't know if there are any washers, spacers, etc. I've been searching like crazy for an aftermarket part with no luck. Does anyone know where I might be able to find one of these? Looked on Auto Zone and can't find anything. Since I can't find any kind of diagram I don't know if I need to get a whole new assembly at the dealer or just a pulley and a bolt. Thank you for any help.

 

I was wrong. The pulley is the tensioner for the A/C belt. One must have tore up the other one so I lost two belts. Found a pulley, Dayco part #89039, so I need that and a nut. Does anyone know if there are any washers needed? Thanks.
