I have recently been having some issues with my '09 Optima going dead overnight on me, even when the battery should have been fully charged. I took it into the local parts store and had them run a test on the battery. As I suspected, it appears that the alternator is going on the car. I am looking to change the alternator myself, as I have done it on other cars (not a Kia) without too much trouble. However, I was wondering if anyone had specific pointers for changing the alternator on a 2.4L DOHC Kia or if there were any guides/diagrams anyone could point me to that might be particularly helpful. I'm a patient guy and I have access to all the necessary equipment, but the layout on this engine is a bit different than my previous experience. Any thoughts that you guys could share would be much appreciated.
