Alright, I have a 07 tl 3.2 and I have recently been having an annoying chirping noise for a couple days now. it all started when i replaced the alternator. a day after i replaced the alternator i noticed my tensioner pulley was dancing so i ended up just replacing the whole assembly and ended up replacing the serp. belt as well. When i replaced those i tried cooling the area with water( not sure if this is the cause). After replacing those it was fine until i turned on my a/c. it started only when the a/c turned on but now its all the time. not sure what to do now....
