DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: Check the coolant reservoir. If coolant is mysteriously disappearing with no visible puddle, the 1.5L/2.0L engine block has cylinder wall coolant intrusion.
- 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.
