How do you replace an alternator?
Well first off if you have the shield under your car then you will have to remove that, 2 screws under the car, 2 screws and 1 popout clip in the front passenger side wheel well(you have to remove the wheel to get to it). Once you have that off you will be able to see the alternator from under the car. Start at the top under the hood, remove your plastic piece that covers the front of your engine bay, once that is off unplug the connectors to the alternator(one is visible and the other is under a black cap you have to pop off and unscrew), there is also a clip holding the wire to the alternator on the shield piece of it(pointing toward the engine, you will see it, it pops out with a bit of force). Once all connections have been removed you will have to slip your alternator belt off the alternator(if replacing belt as well, which I do recomment you just loosen the tensioner and pull it off of all the pullies) then there is 1 bolt holding the alternator in at the top (tough to get to but what I did was stick my arm down the side with a 10mm and wrap it around in front of the alternator and take it off. Once that is removed go back under the car and there is 1 bolt holding it in that you have to remove before it comes out freely. After that your home free :)
Absoutely, tho it's probably built into the alternator. Ask your local auto parts supplier if a replacement regulator is available. Of course you have to disassemble the alternator and install the regulator if it in inside your alternator. lol It's inside the alternator. Either replace the alternator or get a diagram of the alternator and rebuild it.
