This is not a belt, I bet - It is a vacuum hose. My "new" (recently aquired) 89 900 16v was doing the same thing - "screaming" sound only when not under acceleration - was prominent at idle esp. From initial location, sounded like a pump, belt or alternator - then, upon closer inspection, is a whistling vacuum hose - the one coming out of the back/top of valve covers - local Saab specialist says that this vacuum hose starts to soften with age/exposure to petroluem products - vacuum through it causes screaming whistle remarkably like belt or failing expensive thing - suggests replacement w/ 3/16" fuel line.
I find mine varies with temp - I have yet to do the replacement project.
