I'm working on loosening the bolts on the alternator. I got the large pivot at the bottom of the alt loose but I am struggling with the adjustment bolt. i dont have ramps but I can fit under the car and I've tried from down there and from the top with the assembly going from the turbo to the air cleaner removed. Is there another way to get to it?
