Check your alternator mounting bushings. They've probably deteriorated by now.
You'll keep chasing loose belts until you replace them.
If you do it yourself, the polyurethane replacements are far easier to press in,
and work just as well as the rubber.

Re: Noisy in cold weather for short time
The belt tensioners have bearings in them:
I'd advise to take the belt off at night, then spin the tensioners, water
pump, A/C pulley and water pump in the morning when it's cold. That will
isolate the noisy component.
I hope this helps?

How do these automatic belt tensioners know how much tension to apply?
Is there a spring? If so, isn't it possible for it to fatigue?
Thanks in advance.

Yes, spring tension. There are two types. One that has a little
mini-shock absorber looking spring assembly and one that has a torsion
type spring assembly. You'd have to look up your car to see whaich you
have. And yes, either way it is possible for them to go bad.
