If you take serpentine belt off, you should spin the Idler pulley first. If it continues to spin for a bit, then the bearing is bad. If it stops fairly quickly, then it is okay. As for the belt tensioner pulley, they feel gritty when spun tested. You will not be able to feel any difference in your alternator pulley if the internal bearings are starting to go bad. Let me know how you make out and good luck.
hello my friend^_^
I just checked everything and it all sounded great except my tension pulley. Holy moly it was super wiggly and noisy so I just ordered one $247 later🥺. It’s weird because the sound wasn’t even on that side so I’m not sure if the sound was just traveling to the side of the idler and alternator side. I tightened the idler pulley after putting it back on, put the belt back on and for some reason the whining sound is gone now. I’m still going to put my new tension pulley on since I’ve already ordered it and it’s really bad too. Thank you for teaching me how to check the pullies☺️ I also watched some videos and read some articles and they said everything you said so thank you again! I really appreciate you and how fast you responded. Hopefully when I get my new part I can finally play with my car again wahoo! Have a fun day!
