Disconnect the remaining wire connections to the alternator, and lift it from the S-10. Using a small pry bar, pry the alternator upward. Pull out the two front alternator mounting bolts, then remove the rear alternator bracket bolt. Hold the inside nut stable with a wrench, then pull out the outer retaining nut with a ratchet and socket. Locate the black- or red-colored cap cover on the back of the alternator, and pull it off with your fingers to expose the terminal retaining nut.

Remove the heater hose brace, if applicable to your S-10. Allow the tensioner to gently rest back into its applied position, and then remove the serpentine belt tool. Do not remove the belt unless you're replacing it as well. Holding the tool with one hand, use your other hand to remove the belt from the alternator pulley. Then pivot the tensioner to relieve the tension on the belt. Place the 3/8-inch square drive adapter into the serpentine belt tool, and insert it into the square drive on the tensioner pulley.
