If its in the same location as the 92 Buick lesabre it takes about 5 min to replace.
First disconnect the battery.
i forget what socket size you need but loosen the serpentine belt at the tensioner pulley. i believe you need a 14mm socket or maybe a 12mm. but there are only 2 bolts holding it in place. take them out. disconnect the wires. (i think thats a 10mm socket.)
connect the wires to the new one. set it in place, put the 2 bolts back in. put the serpentine belt back on connect the battery and jump it if its dead.
Remove the positive cable from your 1997 Buick LeSabre battery. Remove the alternator belt. Remove the alternator wiring harness. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
