Disconnect the negative (-) battery cable.
Loosen the alternator V-belt tensioning bolts, pivot the alternator and remove the alternator V-belts.
Remove tensioning bolts.
Disconnect the wires from the rear of the alternator.
Pivot alternator away from block to allow access to alternator bracket mounting bolts.
Remove the alternator bracket mounting bolts and the alternator. Note: The alternator bracket must be removed with the alternator to allow removal of the pivot bolt.
Install the new alternator, leaving the tensioning bolts slightly loose. Install the V-belt and tension it. CAUTION! V-belt tension is critical to the life of alternator and proper alternator operation. A loose belt will cause undercharging (and often a loud screeching sound). A tight belt will quickly destroy the alternator bearings and the bearings of other components driven off the same belt.
Tighten all tensioning bolts. Install the wiring to the alternator. Reconnect the battery terminal and check the operation of the charging system warning lamp. Note: Be sure to reinstall the insulating boots to the wire terminals on the back of the alternator.
