How to Change the Battery in a Oldsmobile Aurora


Many owners of the Oldsmobile Aurora have a hard time finding the vehicle's battery. Unlike in most other vehicles, the Aurora's battery is located beneath the rear-seat cushion. Other than removing the rear-seat cushion, replacing the battery in your Aurora is not much different than in any other vehicle. The process is the same for all models (1995 to 2003).

Things You'll Need

  • Pliers
  • Socket wrench
  • AC Delco replacement battery (preferred)
  • Park the Aurora on level ground and turn the engine off. Make sure your replacement battery is suitable for the year and model of your Aurora.

  • Lift up on the rear-seat cushion bottom to release the clips, and then pull the seat towards the front of the vehicle to remove.

  • Remove the battery access cover. Remove the bolts securing the battery mounting bracket.

  • Loosen the locking nut for the positive (+) and negative (-) battery terminals. Lift the cables from the terminals and remove the battery.

  • Install the new battery. Connect the red cable to the positive (+) terminal and connect the black cable to the negative (-) terminal.

  • Replace the mounting bracket and tighten the screws. Replace the battery access cover and the rear-seat cushion.

Tips & Warnings

  • General Motors recommends AC Delco replacement batteries for best results.
  • Do not cross-connect the battery cables. Use the cable colors as a guide when connecting the battery cables.
