replaced alternotor

Hi and thanks for using 2carpros.com

First, I attached a picture showing how the belt should be routed. Make sure that is correct and make sure it isn't hanging up on a bracket or other component.

See Pic 1

If it is routed correctly, release the pressure from the automatic tensioner which should allow you to get the belt over the last pulley. Here is a link that describes the tensioner and how it works:

Let me know if this helps or if you have other questions.

Take care,
Joe
