Review on 🔧 ACDelco Professional 6K930 Serpentine Belt: Standard V-Ribbed Efficiency at its Best by Sidewinders Rains

Perfect for my 2003 Sierra 1500 with 5.3L Vortec (145A alternator). If you don't work on cars much and buy this to replace aging belts, don't forget to also buy a separate AC belt (AC Delco 6K378). If your main belt gets old, your AC belt will probably get old too, and you'll have to remove the main belt to get to the AC belt anyway. save yourself the headache. At least if you have a truck like me.
