I have a 1998 Audi A4 6 CL 2.8 Litre. Recently, I got a new battery because my engine would click and appears that there are no charge. Took it in to a local shop and they said I needed a new battery. Got it as said. But then, yesterday, my car would not start. Making clicking noise as if the charge would go through but doesn't. Called my mechanic and he said its an alternator issue.

He's charging 600 bucks to replace the alternator, which, I think is a bit overpriced. I've decided that I'm going to do it myself. So went to Kragen and purchased an alternator. However, the alternator does not come with a pulley. Is it hard to remove the pulley from the old alternator and use it on the new alternator? What tools would I need?

In addition, is it necessary to change the belt as well?

First off, I don't see how your "mechanic" diagnosed the alternator over the phone. There are many reasons your battery may dead and they can only be found by actually testing components on the car.

As for the pulley, it's either a 22 or 24mm nut holding it on. An impact gun is the easiest way to get it on/off.
If you're lucky the shaft will have allen hex in it. If this is the case you put an allen on the shaft and a wrench on the nut to break it loose.

Belt replacement depends on the condition. If there are any cracks on the serpentine belt, replace it with the alternator.
