How do you replace the alternator on a 1992 Oldsmobile?
Disconnect the battery. Make a drawing of the belt routing. locate the belt tensioner pully and release enough belt pressure so a cohort can remove the serpentine belt off the closest pully. Remove the bolted on battery cable and electrical plug from the alternator and the mounting bolts or remove the bolts so you can access the electrical connection. Remove the ALT. Reverse the procedure to install your new alt. You will have to move the tensioner again to get the belt back on that last pulley.
