High pitched sound in the cold
Hello everyone. I need some suggestions as to what this could be. I have moved to a small town 4 hours from Sydney and the mechanics here don't seem to know much at all about Alfas, let alone diesels. I have noticed over the past few weeks that on cold mornings I can hear a high pitched whirring sound from the engine, separate to the engine noise. It is connected however, as it gets higher pitched as the engine revs up. I have also noted that it's worse when turning the steering wheel, especially to the extremes. The sound disappears when the engine is warm. Any ideas or suggestions? Edit: It's a 2.4 JTDm 159.
