Hey guys, I am not sure if I'm supposed to ask this here but I couldn't find any threads with such questions. If I am not supposed to, please feel free to let me know.

I need to replace my drive belts for 03 G35 Sedan, with in service date of May 2002. My buddy gets parts for me at great prices but he tells me that he's seeing 2 different listings for the one that's connected to the A/C (3rd listing is for the one that's conencted to the alternator).

One 36.5" and another 37.5" for the belt that's connected to the A/C.
Does anyone know which one I'm supposed to get?

Thanks in advance.

 

There was a change on the '03 sedans to electric fans.
That is most likely the reason for 2 belt sizes.
