Ive had really poor luck out of most tensioner and idler pullies available.
Seems they are adequate, however use chinese bearings. Most bearings used there are sealed and non lubed.
Autozone, advance -niether has adequate parts if you are looking for quality.
Go with Gates brand, to my knowledge as of a few yrs back all bearings were federal mogul. Gates brand is in oreillys, napa, and carquest. Belts too.
I spent a long time in parts and many more years bolting them on.
Just what i would look for/ hope it helps.

Squeals but goes away when ADD-weak tensioner.

Fwiw gm used k060947, k060956, k060960, and k060966 belts. Which belt u have? Last three # on belt are length in cm. last number is a decimal. If u have k060956 for example, swap to k060950(think it fits volvo if I remember right) the aftermarket stuff (usually) performs better with shorter belt due to varying tensioner pre-load. Just one of countless useless data i hope proves useful.
That adequately checks the idler-tensioner systemand allows moving on. Next stop is the alternator/ it is stressed the most in off-idle situations and such
The cam in that engine should be a roller, lobe could be swedged/brinneled, you would likely have noticed click from it ticking after full lift on the closing side. 9 out of ten times, if you check the spring it will be weak if the lobe was the problem, unless for some reason you have a flat tappet cam(lets not mention oil and additives nless this is the case). Hope i helped.

Thanks for the info! The tensioner actually came from O'reilly, because that's who the shop partnered with. But I'm not sure what brand it is since I didn't get a receipt. I'll do your suggested test though. The new Dayco belt is part #5060960, but I'm not sure if the old (but good) Gatorback belt corresponds to that exact same number. It squeaks/chirps with either belt though. The cam is still factory roller.
Btw, I'm originally from Corinth, MS, just down the road from you.
