I have checked the internet for instructions on replacing a serpentine belt on my 2014 Tahoe. Unfortunately the newest example I could find is a 2010 5.3 L. The tensioner and routing looks different than mine. On line it looks simple but I'm thinking GM might have changed something that would make this job more difficult. Has anyone replaced one of these belts on a 2014 or later 5.3L? Where can I find instructions on this?
