Alternator OEM KIA or GENERAL MOTORS

The alternator on my 2019 Forte failed.

I bought a used one with 20k miles on it, an new idler and tensioner pulley for around $350. Installed it all myself.

Here is a stock Mk2 65 amp alternator (top) and the generic one-wire GM alternator (bottom). They're physically the same size, and the posts are almost identical in length. The GM fan is indented in the center though, and the VW one is flat. I used the GM fan, cause my stocker is disgusting, lol. I swapped the VW hardware/pulley over, since the GM pulley was obviously no good (flat, not offset).

I would suggest the genuine Kia one, or a professional grade like NAPA's top line or an AC-Delco. I would avoid anything that says "USA Industries" or "Duralast" on it, based on personal experience. In our shop we have had nearly 100% failure rates with those brands.
