DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: Inspect the hydraulic serpentine belt tensioner below the alternator. If oil has leaked down the body of the tensioner strut, it is failing.
- Check Fluid Levels: Verify engine oil level, coolant level in the reservoir, and transmission/power steering fluid condition.
- Replicate Under Control: Note whether the sound happens when moving or stationary, and if turning the steering wheel alters the pitch.
