How to replace the drive belt on 2003 GMC Envoy?

First you should begin by installing a 3/8 inch breaker bar on the drive belt tensioner arm before turning it clockwise to reduce drive belt tension and then extract the drive belt followed by releasing tension from the tensioner arm. The first step for installation includes guiding the new drive belt through all pulleys except the tensioner pulley before using the 3/8 inch breaker bar to rotate the tensioner arm clockwise for drive belt installation on the tensioner pulley. After letting go of tension on the tensioner arm check that the drive belt correctly fits the pulleys.
