I have a 1991 Volvo 740 Turbo Wagon..
I started it up today (-25C outside) it was a little bit rough but after warming it up for about 15 min I started to drive.. I noticed a faint whistling sound, not a squeal but just a little whining/whistle. The whistling eventually became pretty loud and stopped when the car stopped, but started again upon acceleration. I'm unsure if this is because of extreme cold or possibly something in the turbo??? It almost sounds like if you were to whirl a rope in the air and hear the sound of the air passing by it.
Windows are closed, no roof racks, sound is coming from under the hood.
Thanks for reading !! and STAY WARMM brrrr
