can somoen tell me how to install a alternator belt in my 91 ef hatch with a 92 ls motor , thnaks

 

Drop alternator down and remove belt. Install new belt and re-install alternator.

 

Drop alternator down? All that's needed is to loosen the bolt that locks the alternator in position and possibly the one it pivots on. That should allow more than enough movement to remove and replace the belt. Retension belt to spec and tighten the lockdown bolt.
