Cam belt

[BoxsterS]

Can anyone tell me if the cam belts need changing on the V6 and if so at what interval ? (are they chains ?)
I have searched the service schedule and can't see any mention of cam belt changing. There is mention of changing the supercharger and auxillary belt etc, but nothing I can see on Cam belts.
Thanks

Take off the oil filler cap and you can see the cam chains - no belts to change, hence not on the service schedules.

Thanks for confirming that.
