Hello, below are directions. You will see a small square opeing on the front of the tensioner arm. The square end of a socket breaker bar or ratchet if room to fit into that square to allow you to pull up on tensioner.

there is no square hole in the front of the tension pulley.also what is the purpose of removing the airfilter. This is a 2007 chevy impala ls with a 3.5l engine. I haven't gotten any information that is of use yet.

The info sent is for your vehicle per manufacturer. If your tensioner does not have a square hole, then you will need to see what you can use to lift up on the tensioner. In some cases there are special tools for this as well as there is a special tool for the tensioner with square opening. Below is pic of the tensioner and pic of layout. LMk thanks.
