When I turn the key and she starts up, after about 3 seconds I get a whining/squeeling noise.

 

After about 5 mins it goes, but on reving up it still whines a bit.

 

Checked alternator and its not that.

 

If you look at the engine, on the left theres something driven by an auxilery belt. Think it may be that but what is it?????

 

Its deffinately linked to engine revs.

 

Its just really embarrassing when I start her up, lol.

 

Once shes warm it doesnt do it on start up.

the left (as your looking at the engine) is the power steering belt

Are you getting it all the time? it pretty much stopped doing it for me once the weather warmed up. I'll get the alternater and power steering belts off to you ASAP (and the coolant adapter thingy). Hopefully they will sort it out once and for all.

Im not sure is its the belt or not. I've sprayed belt dressing spray on it, so they are gripping good. Sounds more bearing like.

The loud noise goes after 5 mins, but its still there when you rev it quietly.

 

So that the actual power steeing pump?

yes, thats the power steering pump. Have a look here:

Is there any known faults that power steering pumps whine?

 

If not then it could jsut be the belt.

Not that I've ever heard of although may be wrong? I have heard the noise on other cars so maybe someone will pipe up. I think slick petes car had a similar noise when we were at Brunters?? (sorry if it isn't you Pete, just remember hearing it and thinking it was like mine)
