Alternator Belt Tension Sensor Noise / Squeal
I have a high pitch squealing noise that is coming from the belt area on the engine. I had the belts replaced recently at the 30,000 mile inspection and within two weeks, the squealing started upon start-up and after long periods of driving after the engine was warm. I had the belts retensioned and the noise is still there. I started to probe a little more and it seems to be coming from the belt tension sensor / roller. I know that this was not the safest approach but when I placed a little pressure on the sensor roller that is positioned on the belt, the noise changed or disappeared completely. If I can assume that the belts are tightened appropriately after two adjustments,
Am I way off base to assume that the noise could be coming from this sensor and replace it for $70 or should I take this into a dealership and let them charge a $100 just to diagnose? Has anyone else experienced this. I have searched the archives for other belt noises and no one mentioned the issue coming from the sensor.
Thanks and look forward to any help.

I had that too a while ago.
Stop your engine, put some tape on the sensor to be sure the roller doesn't touch the belt anymore and start up you engine. If the noise doesn't come back : that's it! Easy to change by yourself.
Good luck!

It was in fact the Alternator Belt Tension Sensor. Taped it back and no noise. Any quick tips on replacing? Not a lot of room to manuever around the compartment in this area. Thanks again for your help.
