Quick question- torque spec

I'm putting new belts on my sister's 1999 Altima gxe with an automatic transmission. Most of the stuff is pretty self-explanatory but I think the AC tensioner pulley nut should probably be torqued to spec. Could one of you with a Haynes or Chilton's look that up for me? It would be much appreciated. :)

Every metric thread should be tightened to the correct torque value. Metric threads are precision engineered and are self locking when they are torqued correctly. There are at least three different idler pulley and belt configurations covered in general by the Haynes manual for 93-01 Altimas with KA24DE engines. Chilton and Haynes manuals contridict regarding drive belt information. 14mm socket = 10mm nut@33ftlbs torque.
