Noisy as hell xud

[Jukie88]

Hey guys right I even out of a 306 for nearly two years now but have bought the missus a xud my first xud and it is sooooo noisy I've narrowed it down to the water pump which is very very loud and the car has only ever been run in just water so immgunna change the pump regardless

Now the AC pulley is also dried up and making a racket rather than replace as the air con doesn't work anyways I was going to remove it BUT what belt don't need if I delete it ?? Is there such a short belt if so does anyone know the code for it ??

Thanks in advance
