im not sure if they do none power steering b230's, the belt drive's the water pump aswell, now i thin about it i think the alternator pulley is a double pulley so im thinking i can run the belt round that awswell,

what would be the best way to do it? round the crank alternator and water pump? not just round the alternator and water pump?

I would run it round all three, so that if the alternator belt snapped then atleast your water pump wouldnt stop
