Reviews of OEM Volkswagen alternator pulley

The pulley on my 2015 Golf failed last week, and I had oil (grease from inside the pulley, actually) all over in exactly the same location as your photo shows. Also, the protective end cap came off the end of the alternator pulley - I found it down below, sitting on the top of the plastic pan under the engine. With that cap missing, it is possible to look inside the center of the pulley and see the splines on the bolt holding the pulley on the end of the alternator. The bad news: VW does not sell the pulley as a replacement part, you have to replace the entire alternator, which is a $1,000+ repair.

So update on this. I got the compressor back on and I still had the squeal. It ended up being the alternator pulley was seized. Try spinning the alternator fans by hand and if you can’t your pulley is seized. Parts cost me 30 bucks and was an easy replace. Bow she’s running great.

Well, the alternator pulley does have a built in one way clutch that does fail. Most people just replace the whole alternator when it fails (the \"clutch\" starts to slip, usually because it has gotten rusty).

Here's the old pulley. You can see the center section just sort of let go and the outer section started to slip around the center piece... It's tough to see; but there are little tiny cracks along the inside of the out piece. You can also see a chip on one part... The nice, shiny new pulley...

i got an alt pulley off an 82 rabbit vert with A/C... it's longer, sticks out more. i put the 82 vert pulley on my 89 alt, it lines up with the pulley on the crank, the water pump pulley and the P/S pulley.
