    it started last winter on cold mornings
    and now it does almost every startup especially if it sits for a
    its a very loud squeling noise for several seconds and then it
    abruptly stops, the duration varies.
    Turning off/on the AC and heater does not affect it either.
    turning the wheel does not affect the sound but reving the motor does.

    Have you tried a mink coat? That stopped all the spurious loud
    squealing in my Saturn...

    It could be a belt, or wate rpump or a altenator bearing. Use a 3 or 4
    foot piece of heater hose with one end to ear and other in engine
    compartment when it is cold started to locate source by checking areas
    mention above.

    when my 94 SL did this in wintertime, it turned out to be the serpentine
    belt. When was the last time it was changed or belt dressing applied?
