I have come on here to help people solve a issue we encountered on our 2020 1500 work truck with 5.3. As many of you have encountered stretch to fit belts can be a pain to find the right tool to work with their pulley set up. I have pictured the belt configuration for a 5.3 with a stretch to fit belt. I also have pictured a belt configuration for a 6.6 with a tensioner. Took us awhile to find the lay out but we have converted to a 6.6 tensioner part #12654271 and 6.6 idler pulley part # 12695659. Then measured for a belt and has held up great. Way cheaper to convert to a tensioner and serpentine belt then the cost of most stretch to fit belt installer and removal tools.
