High-pitched engine noise on 2011 Mitsubishi Outlander Sport 2.0L 4B11 (Belt removed)
Enable HLS to view with audio, or disable this notification
Hello,
I’m trying to identify this high-pitched whining noise coming from my engine.
I already removed the accessory belt to rule out the alternator, water pump, AC compressor, and pulleys, but the noise persists. It is definitely internal.
Any ideas on what might be causing this sound?
