Two days ago I noticed that when my AC is turned OFF, something in my engine in making a metallic scraping/shaking noise. It clearly sounds like something metal is scraping against something else that is metal while rotating and shaking. When the AC is turned ON, the noise is not as pronounced.
The sound is present when the car is idling and under about 30 mph. At freeway speed, you can't hear it even though the noise is very loud. When you open the hood, the sound is coming from the drivers side, by the belts. Sounds like maybe a bearing is loose or maybe something has gotten into the grooves of the timing belt. I'm not sure though. Maybe an engine mounting bracket is loose and causing something else to rattle and shake?
I don't know when the belts were last replaced since I recently bought it but they don't look very worn or old.
have the same problem?
