Changing alternator.
 

My alternator died on me after everything else thats been going wrong. I finally fixed all my other problems and then driving home yesterday my alt went and the car died. bought a new alt and began changing it. can someone tell me why chevy uses those stupid star shaped allen key bolts on there cars? What a pain in the a**. I got all the bolts out but that one, i didnt have the right end piece and now i kind of f***** up the bolt and am having a problem getting it out of the car. just that one lowsey bolt it sucks.

Because chevy, or GM in general, are assholes that didn't make our cars to be worked on by the average joe. :D Working on my car this past week, I realized how retarded the engineers were when they designed the 3.4L engine and components, and also made me think it would be worthwhile to get a hotrod kit car with more engine room and have an engine that's able to be worked on with some room to spare.

At least now I know if I ever change my alt I'm going to need some of those star head sockets.

it's because they had issues with stripped heads (that was a designers idea of a fix) get a battery too yours will be bad (regular car batteries hate being discharged)
