Removing the Alternator

• 1). Remove the ground battery cable (black), using a wrench.
  
  
• 2). Rotate the belt tensioner pulley away from the belt to release the belt tension, using a wrench, and slip the belt off the alternator pulley.
  
  
• 3). Loosen the lug nuts from the passenger's side front wheel with a lug wrench.
  
  
• 4). Raise the front of your Saturn, using a floor jack, and support it with a jack stand on each side.
  
  
• 5). Take off the passenger's side front wheel.
  
  
• 6). Remove the liner from the passenger's side front-wheel well, using the push-pin pliers.
