How do you replace the alternator on a Buick Riviera?
In order to remove the alternator you must first remove the belt. The alternator is held in place by two bolts and one will require a 13 mm socket to remove it and the other one requires a 13 mm wrench to remove the nuts while holding the long bolt with either another 13 mm wrench or socket. The alternator takes some force to remove it and pry bar might help. PRECAUTION: When using a pry bar do not use a pulley as a pivot for the pry bar, you will ruin that pulley!!!
