I installed a Vortech S-trim kit on my '93 5.0 a couple of years ago, and everything went pretty smoothly. The car hasn't been driven a whole lot in the last couple of years. I recently noticed a bunch of black dust on all the pulleys which is from the belt slipping. If the car is idling, and I crank the A/C, the belt squeals for about 30 secs. The smog pump, and alternator seems aligned as for as I can tell. They must be misaligned in order for the belt to slip that badly (with belt tensioner in proper range). Where do I even begin to fix this? I am assuming I will need to shim the bracket holding the smog pump, and alternator. Thanks or any help!
