Does anyone know what this noise is coming from the engine?

It usually happens after startup and when i drive for about 10min it goes away.

The weird winning noise

Thanks
 
OK cool. Quick question if the belts had cracks wouldn't I be able to hear the sound all the time? The sound goes away after I drive for about 10min

Might be after they get warmed up they become more pliable.
it was kinda of hard to tell from audio clip what the issue is I'm just making a guess at something that would be easy to check.
I always start with the easy checks and work up to to more difficult ones.

My g35 made that same noise. It's the belts. On the 2nd gen FX though it uses only 1 belt. I just changed mine on my FX a few months ago.
 
I paid like 50 bucks for the belt and half an hour labor at the dealer to do it.

@MTN FX, that thread refers to changing it on the 1st gen. The 2nd gen is a little different on the HR motor. I changed it on my G35 myself and it was easy but found changing the belt myself to be a little more difficult on the FX so I just brought it to the dealer. They changed the belt removal process on the 2nd gen unfortunately.
