March k11 1.0L, 2000. Water pump and A/C belt

[Noodles]

Hi guys, i have a year 2000, Nissan March with A/C, power steering and all that jazz. Im having trouble finding the correct belt size for the waterpump / power steering. The one on it current looks like a 3pk, took the belt off and there are no marking on it, would anyone know the correct belt? Cheers all
