    Got a 91 that came from the factory as a mulit-fuel (gas and CNG) set-up. It's never had an air pump installed. Was getting ready to replace the serpentine belt and not sure if it a stock size since it doesn't have the pump.

    Does the airpump use the flat side of the belt or the grooved. Mine has an idler wheel (mounted on the area where the pump should be) that runs on the flat side of the belt. That may allow a standard belt, but not sure. Has anyone seen this type of setup before?

    Any chance you can take a good picture of the sticker on the core support explaining emissions?

    This would be an interesting one to see.

    No help on the pulley issue though, sorry.

    I can take a picture, but it will be a couple days before I'm home again.

    If possible Id take the belt off and take it in to Napa or wherever and have them compare it or just take a number off it for your new one.

    Yeah, do a length check or sometimes they will have numbers on them that the Napa guy can cross reference to.
