Question about 1997 Buick LeSabre
Tell somebody to rev the motor and check where the problem is from, otherwise remove serpentine belt, if it's a supercharged model remove supercharged belt before, and remove the accessories belt ! tell him to start the motor a short time to see it the knock sound is there or not, if not check each pulley if there's any loose or strange noise while turning them !
