2002-2014 Volvo XC90 Alternator Replacement

ID: 212325

Description: ​This guide provides step-by-step instructions...

Steps:

  1. In the cargo area, lift the floor panel to access the battery. Use a 10mm wrench to loosen the nut on the negative (black) terminal connector and pull it off the post. Secure the cable away from the terminal to prevent accidental contact while you work.
  2. Remove the two 10mm bolts holding the coolant expansion tank in place. Carefully lift the tank and move it toward the engine, securing it with a bungee cord if needed. Do not disconnect the hoses; you just need enough room to reach the alternator.
  3. Locate the serpentine belt tensioner. Using a long-handled ratchet with a T50 (or T55) Torx bit, rotate the tensioner to release pressure on the belt. Slip the belt off the alternator pulley.
  4. Locate the mounting bolts securing the alternator to the engine block. Use your sockets to remove these bolts. Note that the space is tight, so a ratcheting wrench or a shallow socket may be helpful here.
  5. Carefully pull the alternator forward to access the back. Remove the plastic cap and unscrew the nut holding the main power lead, then depress the clip to remove the wiring harness connector.
