1. Turn ignition switch on (without starting engine) and turn wheels fully to the left (as though you are making a left turn). This will provide plenty of clearance to the torx fasteners at the rear of the left front wheel well. Once wheels are turned, shut ignition off and remove key.
  2. Using a T30 torx head wrench, remove the top three fasteners at the rear of the left front wheel well liner. These are located just in front of the left front fender at the outer side of the wheel well liner.
  3. Using a 10mm socket, remove the bolt at the rear and top of the fender. You can now carefully "tilt" the fender panel outward.
  4. To provide additional clearance for the fender, use an open faced 10mm wrench and loosen the bolt at the bottom of the fender. There is a narrow slot through which you can insert the wrench. I small flashlight is helpful in seeing this bolt. Since the bolt is upside down, make sure you turn it in the correct direction to loosen and later re-tighten it. Once you have loosened this bolt a few rotations (without removing it), you can now tilt the fender outward enough to have plenty of clearance to lift out the old battery.
  5. Using a 13mm socket, remove the battery hold down clamp located at the bottom middle at the rearward-facing side of the battery. There is pretty tight clearance on this, and I had the best results using an 8 inch 1/4" socket extension bar, approaching the hold down bolt from the top.
  6. Disconnect the cables from the battery using the correct size metric socket 8mm. Remove the negative cable first, which is the outward cable, followed by the positive terminal cable.
  7. Once the cables are disconnected, carefully lift the outward side of the battery slightly upward to lift it above the retaining nubs in the battery tray (in other words, you can't just slide it straight out). Once you have cleared the battery tray, you can now lift out the old battery.
  8. Remove the battery insulation sleeve from the old battery and transfer it to the new battery (AC Delco 75-7YR).
  9. Lift new battery onto the battery tray and slide it inward into place. There are some wires running down the back which are very tight clearance to the battery, so make sure you hold these rearward while sliding the battery in so that don't catch the battery insulation.
  10. Reinstall the hold-down clamp.
  11. Connect the negative battery cable.
  12. Connect the positive battery cable.
  13. Lift the fender panel back into position and just start to thread the top 10mm bolt.
  14. Reinstall the three T30 torx fasteners in the wheels well splash panel. Make sure the fender panel is aligned correctly so there will be no interference with the driver's side door's range of motion.
  15. Tighten the top 10mm bolt with the fender panel in correct alignment.
  16. Tighten the bottom 10mm bolt.
  17. Start car and be happy again ;-)

A couple of notes. On my car, the battery was definitely dead. The engine fired right up with the new battery. Also, the correct AC Delco replacement battery (75-7YR) has the condition "window" located on the wrong side (near the positive terminal), so it is not visible once the battery is installed.
