I have a 2012 grand sport with dry sump. It needs a new ac belt.
P/N is 12636224 which GM has discontinued. Does anyone have
a recommendation on what belt to use? Thanks in advance

Double check compatibility, but I believe this is the replacement from Gates.

I use the Continental belts.They are the replacement belt for the Goodyear Gatorback belt.

Would back it up, and why do you need a new AC belt. Is the A/C tenser pulley going dry and what took the belt out, or is the Ac clutch bearing dry, and what took the belt out? Hence tensioner pulley is easy to pull to re-grease the sealed bearing, as well as the A/C clutch bearing ( and what may be making the noise,with the old belt still fine.

There is an AC Delco equivalent as well, 4K418. I just ordered this one last week, it fits right and doesn't make any noise.

Got this one at Advance Auto a few months back. Fit my 2013 dry sump GS.
