Tips & Tricks

  • Access the accessory belt tensioner from the bottom — it's very difficult to see from the top.
  • Apply penetrating oil to the power steering pump bracket to help it slide out.
  • Tap the metal insert on the power steering pump mount rearward to spread the gap and ease reinstallation; apply lubricant to the mating surfaces.
  • Unbolt the sway bar before attempting to remove the alternator — it's nearly impossible to extract from the bottom with it in place, and removal also improves ratchet access to the lower alternator bolts.
  • Remove the 12mm bolt holding the transmission oil cooler lines to the engine oil pan so the lines can be moved out of the way of the lower alternator bolts.
  • Disconnect the oil pressure sensor and nearby harness clips to gain enough clearance to extract the alternator.
  • Check the two alignment dowel sleeves after removal — they can stay stuck in the block or in the alternator; ensure one is seated at each location before reinstalling.
  • The alternator sits on a stud at the top, so the top bolt will come out but the alternator won't drop until pried off the stud.
  • Moving the power steering pump as far forward as possible before unbolting the alternator gives better access to the top nut and bolt.
