I’m getting a bit of a squeaking noise while running but it only
seems to happen when warmed up and it might be random sometimes it does
sometimes it doesn’t happen. So is this the serpentine belt needing replacement soon?

Very possibly, they are cheap, but you can diagnose by spraying water on the pulleys when its squeaking. If the squeak goes away, it is the belt, if not, it is likely a bearing going out. Use a listening device when squeaking to determine which one (alternator, compressor, PS pump), or, after removing serp belt, spin them and test for smoothness, true. A lot of youtubes on this subject...

well the very reputable shop down the street from me where I get my oil changes done at did tell me there is a slight squeak/rattle coming from my alternator which at least for
now I Hope is nothing major as I don’t want the alt bearing to lock up on me causing me to be stuck somewhere due to a battery that won’t charge cause of a frozen alt bearing.

Good luck! I hope you get it resolved and I am looking forward to hearing about your success. It is always fun to learn something new although not so much fun when you are the guenie pig.
