2022 2500HD Crew Z71 Duramax single alternator. Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

2022 HD 2500 here, just locate the micro switch under the column cover, snip the 2 wires and connect them together (solder if you're skilled or wire nut if you're not) thereafter be SURE to put it in park 'cause you won't ever get a reminder again. no collateral damage afterward on mine. cost $0.0

thanks kylant just found your old post, had this issue after changing filter myself & DIC wouldn't reset, my '22 2500 Duramax reset immediately following your advice.

no luck at cws.gm.com with my 2018 Silverado. at gmmediaarchive.com put vehicle invoice in search box, complete form and pay $50
