How do you change the alternator on a 1994 Saturn SC 2?

Answer 1

You will need to remove the passenger front tire and take apart the plastic splash guards to get to the alternator. Loosen the serpentine belt tensioner and remove the belt. Disconnect the negative battery terminal or you will get sparks when removing the wires from the alternator. Now crawl under the car and remove the plastic cover from the alternator, I think it is a 10mm bolt, then disconnect the wires from the alternator, one plug-in connector and I believe one wire held on by a 10mm nut. Now for the real fun, you will need a pair of wrenches, or a ratchet and a wrench to remove the nut from the lower mounting bolt on the alternator, remove the bolt. The upper mounting bolt is not so easy to get too, but a lot of swearing and small hands will find it, add a little patience and it will eventually come all the way out. When both mounting bolts are out you will find the alternator will pivot on the lower mount, wiggle it until it comes off the lower mounting bracket. The alternator will only come out of the engine bay via the passenger wheel well, just rotate it until it looks right and pull it out. Installation is the same process in reverse. Good luck
