I am about to change both belts on my 2007 SL and am trying to decipher Nissan's confusing part naming system. The only belts that seem to be available are an "ac belt" and a "serpentine belt." When I look up both belts in a few different online stores I get the same results: (http://www.partswebsite.com/nissanpa...n=1&type=parts).

My questions is, is this "ac belt" another name for the ac/alternator belt and is the "serpentine belt" another name for the power steering belt? Or better yet, does anybody have the exact part numbers for these two belts?

Thanks

 

Yes

Power steering - 11950-8J100
A/C & alt - 11920-CK000

Or Dayco:
Power steering - 5040305
A/C & alt - 5060418

 

Thanks

 

I see multiple part numbers for the same engine in other Nissan models such as the Altima and FX35. Are these belts different lengths due to different pulley sizes or just an odd way for Nissan to align p/n to car?

I get two part numbers for the main belt. It changes for the CVT cars apparently. I was trying to order from MyNismo.com and they list the 11920-CK000 belt under the Nissan Quest. Confusing...
