How do I replace the alternator on a 2005 Chevy Equinox?

My alternator just bit the dust, but I don’t want to pay for the added cost of taking it to a mechanic. Can you tell me how to replace the alternator on a 2005 Chevy Equinox?

Here’s how to replace the alternator on a 2005
Chevy Equinox
:
  • Open the hood
    and remove the engine cover, air box, air tube, and battery.
  • Disconnect the wires that connect to the EGR valve and tube, the map sensor, and the idle hose. You’ll need to have these unplugged so you can access the alternator.
  • Unbolt the tension harness connected to the alternator
  • Your alternator is held down by three bolts: one on each side and one in the back, unbolt all three of these bolts.
  • Take out the old alternator and replace it with your new one.
  • Re-bolt the three bolts you took out earlier to hold your new alternator in place
  • Reconnect everything you disconnected earlier, and reinstall the battery
When replacing the alternator on your 2005 Chevy Equinox, it’s helpful to have your owner’s manual on hand. It will provide a thorough engine diagram to help pinpoint exactly what each part looks like and where you can find it in your engine.
