I changed the belt tensioner assembly 1 month ago, everytime i turn the ac on it gets louder when the ac is off the noise is still there but not too loud

UPDATE: Belt and tensioner bolt broke again. That was a 12.9 bolt. The belt has always been incredibly difficult to install and ended up being super tight once installed. Overly tight. I installed a new tensioner and used a longer belt. Part number 6PK2155. This fixed the issue. I first thought maybe one of the accessories(power steering pump, ac compressor or alternator) was possibly locking up under load or maybe even the wrong part for this vehicle. I took alternator off and compared to one from the store and it was correct. I could not get it load tested as no one in town apparently had the correct connector on their load tester for this alternator. However all pulleys spun freely so I don't think any of the parts are necessarily bad. I did not remove ac compressor or power steering pump to compare but either way the longer belt remedied the issue.

Did you have to remove the radiator to take off the mounting bracket?

When we had to revisit this repair a month later we didn’t remove the radiator. When we first filmed this we just went ahead and removed it for more space. Not necessary though!
