Alternator pulley and fan

[69L89396]

What is the correct finish for the alternator pulley and fan?

[Keith Tedford]

I just bought a replacement fan from GM to see what the differences were. They are different in minor but obvious ways and are galvanized. Can't recall the original finish but old photos show the fan to be silver coloured, possibly galvanized.

[Mr Yenko]

That is correct, they were galvanized. But have yet to find someone that can do it correct. I guess with the chemicals used in this process it is impossable for them to duplicate.

So what is considered or accepted to be correct?
Also what about the pulley?

Silver or clear zinc.
