About GM Alternator

A GM alternator holds the primary task of giving electricity to your many electrical accessories, and at the same it charges the 12 volt battery in your vehicle. Alternators are driven by a pulley while your engine is running. This pulley spins the parts inside of the alternator, and this in turn generates electric power for your vehicle. Many alternators are found at the front of the engine, while other vehicles have them on the side of the engine. Wherever you find your power steering pump or A/C compressor, you will see your alternator very close to these accessories.
If your GM has an electrical overload, it may overwork the alternator to the point where it will stop working completely. When you discover you have a down and out alternator, it's time to replace it. The process to do that starts with disconnecting your negative battery cable. After that you will need to loosen and remove the alternator mounting bolts, take of the pulley, then remove and replace with the new alternator. When you buy yourself a brand new GM alternator, you will have peace of mind in knowing that it is the same part used straight off of the GM factory assembly line.
