What are amps on stock alternator for 2013 Impala?

have seen 170 amp and 220 amp based on your question~ Google it, it's what I did~
The amperage should be stamped on the alternator. You can also take a picture of the RPO sticker, usually on the inside of the glove box door, and take it to your local Chevrolet Dealer. They can decode it and tell you what alternator you have. Hope that helps! Jim
