Does anyone know the correct part number for a 3.8L serpentine belt with A/C?

I ordered one for a spare but now think I got the wrong one! I received part number 53032857AB which seems to be for a non A/C JK according to some websites.

According to my 2011 JK parts book, that's the part number for the belt with A/C.

The part number for those without A/C is 04593684AA

Are you sure you are routing it correctly?

Ok, great. Thanks!

I haven't installed it yet, was looking up the routing diagram when I came across the conflicting part numbers.

The factory serpentine belt part number is: 53032857AB for the 3.8L with A/C; this is the belt I presently have in my '11.
The Goodyear Gatorback belt part number would be: 6PK2285 or 4060900.

Go with the gatorback belt. I have been using these for years. They are of better quality than the OEMs, and will last a lot longer. Well worth the extra couple bucks.

According to everything Ive read, you have this completely backwards - 4593684AA is WITH AC

Well, it can't be according to everything you've read if you read post 4, above. He has A/C and is using belt #53032857AB, as am I.

According the the 2011 parts book, 53032857AB has sales code HA0, which = with A/C, and 4593684AA has sales code HC0, which = without A/C.

I guess the best way for me to know for sure is to go out to the barn and look at the JK.
It's 6°F out there, so I may not do it 'til spring.

OK. I went out and checked. I have belt #53032857AB, with A/C.
