1. Take out your car battery and have it charging while you work. 2. Loosen up your power steering container. The hoses can stay connected. Just loosen the bolt. 3. Undo all of the electrical clips that are on the fan so that you can remove the entire fan. There are two bolts on the top and one bolt on the bottom. I reached down with a 10mm socket and took it off (If you have trouble try putting the socket on the bolt and then the wrench into the socket for an easier fit. The fan should lift completely out. The hardest electrical clip will be on your lower left. That one is actually just clipped to the fan so unlike the others, you're taking it off the fan and not separating the wire plugs. Raise your fan out. 4. Take out the green plug off the alternator. 5. On the right side of the alternator is wire going in that is covered by a rubber plug. Pull off the rubber plug and use your 10mm socket to remove that bolt. 6. Loosen the pulley for the alternator. The bolt you're looking to loosen is NOT the large bolt of the pulley attached to the alternator but rather the next one back (back as in towards the back of the car). Just loosen the bolt (14mm I believe) in order to take the belt off the pulley of the alternator. 7. My next advice is to loosen the clamp that you'll see on top of the alternator (your green plug wire runs through this. Loosening this up will make taking the alternator out a breeze and is a cinch to loosen up. 8. Take out your two primary bolts holding the alternator in. 12mm socket should do this for you. 9. You should be able to pull the alternator out with ease especially if you followed step 7.When checking the price of your replacement alternator be sure to know what the cost of your alternator will actually be. You'll see the price plus the core cost. By this they usually mean $145.99 Core $50. This means you'll pay $195.99 if you don't bring your old alternator (IE your Core) in first. If you do, you'd pay $145.99 plus sales tax.
Tools: Have a set of wrenches, sockets (14, 12, and 10mm), and a pointer magnet is highly recommended.
The whole process is rather easy if you know what you are doing. I didn't but now I do. I've tried to include the basic information I didn't know. Good luck! You can do it.

Changed alternator still is not charging 1996 sunfire gt


The alternator output is regulated by the ECM. If you have a known good alternator you have either a wiring problem or a bad ECM (electronic control module).

I'm changing the altanator on a 1999 Pontiac Sunfire. How do I release the belt tension?


Loosen the tensioner for the accessory belt for the alternator and remove the belt. Remove the two long bolts that are holding the alternator in the bracket.
(Sometimes you have to remove the tensioner arm completely or just loosen it and it will slide over to relieve tension on belt)
