How do you replace the alternator on a 1996 Buick Regal?
Best to get a shop manual for this operation, if you have not replaced it before. Usually there is an "Idler Pulley" on many late model cars that is "spring loaded". You "Bias" this pulley (usually with a socket wrench) so that the serpentine belt has enough slack in it so you can remove it. Then you disconnect the Positive Battery cable, disconnect the "Field Wire" harness and Positive battery lead from the alternator, unbolt and remove the alternator. Reverse procedure to install new alternator. TommyTrouble
