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,

BM

I read on a Swedish site, there someone described the noise as you did, and
the solotion was simple
in hes case it was the engine oil filter bypass walve that make the sound.

Change your oil filter thats no more to it.

förlåt 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).
You: väluppfostrad, me: obildad.
