2000 9-5 Aero Hydraulic sound/noise

I am experiencing two sounds from the engine compartment that I have been unable to identify and would like your help.

When starting out cold (I am located in New England) there is a sound like a squealing v-belt. It only makes this sound when the engine is cold and until the temp needle begins to move off the pin. The second sound which I think is linked to the same source - is one like that of a whining power steering pump. You know, the hydraulic sound.

To date I have replaced the power steering pump (with a used one); the water pump; Steering rack (rebuilt); serpentine belt and tentioner pulley. Oh, I replaced the alternator with a Bosch rebuilt, too.

The sound is strikingly similar to the teering pump on the early 90s 9000 models, but I have already replaced the pump. Am I missing something here?

Thanks in advance for your assistance.

Regards,

Change your oil filter thats no more to it.

f=F6rl=E5t Sid, I didn't intend to poke fun at your English: I thought it was just a typing error. Your command of English is magnificent compared to my Swedish, so congratulations. (My command of Swedish is zero). =20 You: v=E4luppfostrad, me: obildad.
