I have a 2001 Ford Escape V6 Engine.
I recently noticed my engine is really loud when I drive it. I ran codes and the only codes I received were about cylinders misfiring, which is a whole other issue.
The engine is making a screeching noise. I removed the serpentine belt and noise goes away, but the belt is in good condition. I spun the alternator, A/C compressor, tensioner and that middle pulley by hand and they’re all smooth.
