This is a Bosch 105 amp alternator. It can be found on many GM cars from 1999-2004 with 3.4 or 3.1 engines. The 4 pin voltage regulator plugs in the back of the alt. This style Bosch has an internal cooling fan. These alternators are known for bearing failure after 150k so if you hear a grinding noise, this may be the culprit.
Kit includes : Front and rear bearing, rear bearing tolerance ring, voltage regulator/ brush ass’y.
