Hey all! I recently just bought my 2005 Tl grey beauty not too long ago with 131k miles with all service records in hand. But just tonight I noticed a slight squeaking that wasn’t there previously. I don’t know if you can hear it in the video, but it’s very faint. It sounds like part of the pulley noise. I just want to know what all of you think.

link to the video:

 

Spray a small mist of water on the belt with engine at idle. If it stops, belt, if not, remove the drive belt, start the engine and see if noise present. If not, probably tensioner/pulley, but also spin alternator pulley to check for any noise/looseness.

 

do you have pictures of the specific belts? I’m not very experienced with cars. Also is it safe to start a car without the drive belt??

 

Open the hood and you'll see a belt on the left.

 

And which belt might that be?

 

The serpentine belt. You won't be able to see the timing belt because it's under the timing cover
