Why Is My Car Making a Whining Noise?
The source of a whining noise depends on speed, RPM, and when the sound appears. Common causes include:
- Whining Noise When Accelerating: A noise that rises with RPM may come from belts, pulleys, alternators, or drivetrain components.
- Power Steering Whine: A whining sound that changes when turning the steering wheel may be related to low fluid, a worn pump, or steering system components.
- Transmission Whining Noise: A whine that changes with vehicle speed or gear changes may indicate transmission fluid issues or internal wear.
- Alternator Whining Noise: A high-pitched sound from the engine bay can sometimes come from alternator bearings or electrical components.
- Serpentine Belt Noise: A worn belt or pulley can create a continuous whining or squealing sound.
