Strong sharpening knives noise about 3 minutes after I start my Toyota Corrola 1997. Noticed it lately when the weather is below 20 F. Colder it is the longer it lasts. I noticed that the timing belt moves slowly until the noise is gone. (I don't have an RPM meter). Also notce the same noise when I turn the car in the cold when performing slow sharp turn. Also noticed that if turn my radio lower or heater lower when the noise suddenly hits me on the road - the noise stops. Could it be the alternator? Is it a problem?
