Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

My alternator is still charging perfectly but is a bit noisy. I confirmed this today when i replaced the belt and carefully felt all bearings. Alternator was ever so slightly rough. Any reason this couldnt be rebuilt rather than replacing?

POST 2Original post

Rebuilding with an alternator/starter specialist is a great approach and much cheaper than new.

POST 4Original post

Mine was replaced just before I purchased mine a little over 3 years ago. $1,145 plus $217 labor. If there is a way to rebuild it I'd definitely opt for that.

POST 5 / ORIGINAL POSTEROriginal post

Thanks guys! Yeah, I saw the prices of new ones from Porsche, as well as Bosch direct units. I couldn't see why, but figured I'd ask to see if I was missing anything.

POST 6Original post

Look for a post a little while back, it was about a good deal on Amazon and the 997 ( same as 996) alternator. It even includes the pulley. I bought one and I think it was around $200. And it is a new Bosch unit not rebuilt one. Plus a little more power from it too. Might be worth checking out as an option. Jeff

POST 7 / ORIGINAL POSTEROriginal post

That was the 150amp unit right? Yes, I saw that and would be my second option to a rebuild (or if the rebuild didn't work out)

POST 8Original post

Don't buy a Chinese eBay version. Keep your factory alternator and have it rebuilt. I've got an excellent shop nearby that did mine for $110. Those aren't rare, just look for an alternator and starter specialist.

POST 9Original post

I replaced my alternator a couple years ago, Bought a re-manufactured from Advance Auto, was $159 with lifetime replacement. compared the 2 and it was identical to the one I removed.

POST 11Original post

Identical ? Sure the outside case - but what about the bearings , diodes etc. I went with San Jose starter and alternator (I'm sure there are local shops like that in many cities) who rebuilt with German parts for me ... ~$200 .... Perfect

POST 12Original post

When you are removing the alternator - good time to replace the plastic coolant tee and oil filler hose if those are old and brittle ...

POST 13Original post

I actually ordered the Amazon 150A alternator and just received it yesterday. Looks great and I can't wait to install it. I'll let you all know how it turns out once I've done so. Even with taxes it was less than $300 and Amazon got it to me in a couple of days. Brand new and without a core charge.

POST 14Original post

Quotes source post: 13450319

Now go have your old one rebuilt and save it for a rainy day!

POST 15Original post

Replace the alternator-starter y-cable while you're in there. If it has failed yet, it will. Promise.

POST 16Original post

Agree 100% on above post. It's easier to do it too.

POST 17Original post

If you use an aftermarket alternator don't be surprised if your radio starts to cut out. My C2 had an aftermarket alternator when I got it and the radio cut out every time I started to drive the car. It turns out some of the factory radios on the older 996's can cut out when there is too much current. My voltage regulator was intermittently sending out too much juice (it looked just like the factory Bosch one). I ended up putting a resistor in my fuse box to cut the power down. Worked like a champ.
