How to replace your Alternator - Pictorial

Recommended Posts

Thanks for a great write-up.

I just did this job (although I only replaced the regulator on the back of the alternator).

I'd like to add a couple of points I found when I was doing the job.

1) Removing the "Y" pipe; you can easily slip the little vacuum hose off the other end. It's attached to the pressure solenoid and slips right off. You can then remove the whole "Y" pipe with the little vacuum hose still attached. The solenoid is a known problem and at about $20 worth replacing while you're in there.

2) When you release the tension on the belt don't use the 24mm nut. If you look carefully there's a 15mm nut attached to the mounting arm. It's heaps easier to get the tension on that (It's the correct way to do it as well!).

3) The alternator is a pig to get out but you can make it tons easier to put back in by putting the steel bush end of the alternator main mount in a bench vice and gently pressing the bush outwards a little. I found this great tip in this tutorial (scroll way down) and it works like a treat!http://www.dakingrulez.com/porsche_996_turbo_Gt2/diy/remove_alternator/porsche_996_turbo_gt2_remove_alternator.shtm

4) While you're in there clean your throttle body too, use throttle body cleaner. Also clean your MAF as you've got that out too. Make sure you only use special MAF cleaner on it, NOT the throttle body cleaner.

I also replaced my drive belt too as it was due. It's actually a snap to do, it's much harder to get it out. Putting the new one on took about 2 minutes, it literally "fell" into place. Loren has a tutorial on the belt in the DIY section, but it's fairly straight forward.

Hope this helps.
